My Third Sprint: A Lesson in Legacy

                With the ending of my last sprint in my capstone class I have completed my first of many cycles of development. Throughout this series of three sprints I have gained a better understanding of what I can expect of myself and how I can begin to improve my performance in an actual working environment. This last sprint, like the previous two before, taught me new concepts that I had not previously considered when going into the sprint. Throughout this sprint, especially in the last two weeks, the mains idea that stuck out to me was that of legacy, and what our group leaves behind for those who are coming next.

                When beginning this sprint, I had first focused on what was laid out during the planning session, involving the implementation of docker and containerization in general on to our identity access management system. The system worked when running on the operating system without any overhead so the next step was to get it working with docker to later be adapted to the Kubernetes clusters being used to host the Libre Food Pantry system. On the second of three weeks into this sprint, it had occurred just how close we were to the end of our journey and I began looking at the other spring backlog items. The one that struck me as most important was working on refining existing tutorials within the GitLab repository for the next group of developers to be easily able to get up to speed on what has been done and what needs to be done.

                As in previous sprints, time estimation, while once again improved, was a problem for us. This was especially noticeable as the end of our journey loomed closer.  While we had not gotten as much done as we would have liked to, we had made a concerted effort to condense our findings into the important information and save it to the GitLab repository for future groups to pick up on.

                Our group was tasked with creating a presentation for the end of the semester and this helped us to filter unnecessary information and include only the most important parts that applied to the project at hand. To go along with this I myself had even created a tutorial video that exemplified all of my own findings which would allow new groups to create a secured application with key cloak. Despite being a basic webpage, it is better to start with this than with nothing like our group had.

                As a group we can still improve not just on our time allocation but also our recording of information. Being able to properly record our finding as we make them is important in allowing both the group and future developers to have easy access to pertinent information regarding this project. I myself could have made this a focus as I performed research from the very beginning and would have had a library of information for it.
                Aside from this however, I still have a long was to go in making an effort to communicate with my peers. I often find myself “suffering in silence” whenever I run into a roadblock and, just as before, I tend to withdraw and become distant which benefits no one at the end of the day.

                Overall however I can say with certainty that there is a foundation here for future developers to work on. Our legacy will have an impact on future progress and provides a point for future groups to jump off of in order to finish what we started. The updated ReadMe created in the repository will hopefully hold useful information to users that takes away from the research that would have been spent on getting key cloak working in the first place.

Sprint Retrospective 3

The third sprint for my software development capstone class was on an honest note a bumpy road. The purpose of the sprint was to start the next level implementation of creating test files using mocha and chai and also making sure the API is validated and can be bundled properly. Through the first part of the sprint, the team has been very productive in keeping up with the issues we made for ourselves. After Spring break, our productivity started to plummet since we did not accomplish issues the following, we did not have our class meetings.

As for my team members and I, we have faced great issues that we started to come across that stumbled all of us. Due to facts of, lack of knowledge, merge requests, and was not able to accomplish all our issues for the sprint. First, when it came to merging requests, I admit we have gotten better at how Git operates. But when it came to approving the request assigned to us. We had a pile of request that was not merged and had to spend our class meetings squashing all of the time to keep the main repository up to date as soon as possible. Secondly, our productivity has plummeted since our spring break, we did not have to work on anything which was completely optional. However, the following week there was no class reunion and I made no effort and treated it like another extension of spring break. Third, as I gained a deeper understanding of the problem, I didn’t know how to deal with some of the issues. The other issues couldn’t be resolved and were interrelated, so we had to address them in the next final sprint.

Our team decided not to undermine our productivity. Especially if the third sprint is the last race in the podium category. We decided and wanted to be more active and help each other in the workspaces when there are things we don’t know or understand. Talk about gathering information on all the advice our professors can give us to put us on the same page.

As for me, I have done good things, but of course, I could have made better improvements and made a better contribution to our team. I wanted to know more about how the Mocha and Chai tests were implemented. However, I have decided to do more key pieces to solve the problem. However, in the next problem, we will use one or more of the problems we created to create a more robust test file that will pass all tests. Talk to team members who have done an extensive research to see if they can help you with modifying and implementing test files that have already been created. At least the experience provided.

Sprint retrospective 3

Here in sprint 3, things seemed to have progressed smoothly with the project in that we have finished most of what we have added in the product log although there were some areas of difficulty. The cohesion of the group has improved with better communication on what is to be done and the planning together seems to have gotten better. There are still improvements to be made but overall, the project is in a good state right now. The presentation also seems to be going well and should be alright. The quality of the sprint overall seems to be up and is providing good results.

On what has worked well, we have managed to get to the end of the semester and be able to finish a good amount of work on the project. We added more calls to the backend and continuously updated the API with new changes. The backend is set up with the proper semantic versioning. The android nest tester is functional and everything that we have built looks to be solid. The communication in the group looks to have improved as people communicated on what they did and were working on more than in previous sprints. The team also seemed to have gotten together more often to work on issues. The group stuck to what was planned pretty well and followed the timeline agreed upon. The issue board moved along more than the last sprint, issues were moved across the board compared to last sprint where nothing was moved until the last day.

On what has not worked well, there was unfinished work at the end of the sprint that now has to be sent over to next semester. This means that we have made mistakes during our planning on the difficulty of the work on the issues. The planning of getting the presentation done also could have been better. There probably should have been more dedicated time to get together and figure out the presentation as it felt a bit odd at the end figuring out what topics to do.

We could improve as a team by firstly, we could have worked together more regarding the issues regarding key authentication that we were unable to implement. There could have been chances to get together and try to figure out what was wrong and get it done by the end of the sprint. We could also improve as a team in our planning and plan more effectively on what can be done this sprint. We also could have been more planning with the presentation and knowing what exactly what portion each member was contributing with.

I could improve personally by putting in more of my input and getting my ideas out there. I also could have contributed more on different issues within the project. I also could have done better with working together with the group members such as when we were working on implementing the range call where it felt like backseat coding and I could have contributed more.

Sprint Retrospective 3

Everything under source (src) in backend was written except for the final test files and API was also complete. We were waiting for more information about access tokens and Gitlab access keys from the IAM team. We were also waiting to hear from AWS team on templates for Kubernetes system but did not get any response. We were at the same time researching on how to import API bundle into backend so we could start building the backend server and to at least test if everything from our side was working properly.

We needed to bundle our API before we could export the file to backend and ‘npm run bundle outfile.yaml` was not working. After fixing minor issues in the API, we got our bundle file. Even after a lot of research, readings and experimentation, we were not able to connect API bundle to backend, something would not work and kept getting different errors. At this point we decided to copy the bundle file and paste it into backend lib folder manually. Since we were not able to import the bundle file, we decided to not work in main and created a separate branch called ‘issue10’.

We made a lot of mistakes from this point on. We were all working on this branch instead of making our own branch based on the issue10 branch. We also worked only on one team member – Christian’s system. We added and modified a lot files like entrypoint.sh, package.json, package-lock.json, docker-compose.yaml, Dockerfile, etc. We should have created branches based on issue10 branch, then created specific issues with proper weight assigned to them. After making all the modifications we could think so, we still were not able to build our backend server.

At this point, Dr. Wurst pointed out that we do not have frontend, which means that our docker file will not be copying yarn file and running yarn install but instead copying the package-lock file and running npm install. After making changes in the Dockerfile, our backend server was finally able to build but still could not stay up. After going over docker container logs we finally came to the conclusion that the problem for this was in the port. We had not specified proper port in many files. Once those modifications were made the backend server was up. Till this point, we were all still working on Christian’s system, without any proper issues, comments and documentation for modifications that were being made.

I created my own branch based on issue10 and then wrote calls for cooking method. However, when I tried to build the server, I got the error that docker-compose is not installed even though I have used it many times before. Using the solution, I found on stackoverflow I was now able to build the server but the process would hang up on the attaching stage. I tried running docker-compose up command after opening the branch in container. This led to an error saying ‘docker not found’. Another team member Jeffery had the same problem as mine but was able to find a solution for it and then was able to make calls. However, the same solution did not work for me. After trying everything I could find on the web till 4 am, I finally gave up.

In the next meeting I shared the calls I had written for cooking methods with the team so they could be added to the project. Noticing that I was the only person who was working on a windows PC I decided to run the project on a friends MacBook and surprisingly it worked. I did not research further into why it would not work on my system since I had limited time with the Mac.

I worked on cookingMethod.js and cookingTip.js test file. I set three constant variables: getAll, getOne with valid ID and an invalid ID. getAll would check for ‘200’ response and data in form of array. getOne with valid input would check for ‘200’ response, ID, object and value. getOne with Invalid input would check for ‘404’ response.

Sprint 3 Personal Retrospective

This final sprint was much more of a struggle than the other two prior sprints. Since we got a lot of progress done in achieving our goals throughout the past two sprints, we figured that this sprint would let us bring everything together and finalize everything we have worked on up until this point. Unfortunately due to unforeseen issues, we were unable to reach all of our goals, an we were instead stuck on one task for a vast majority of the sprint. Our goal this sprint was to test the backend and the endpoints to ensure that they can all work with each other in the way that we planned. We initially thought that we had solved many of the issues with the backend that have been plaguing us in the past sprints, but unfortunately that was not the case. In order to test the endpoints we needed to be able to run the backend, and when we attempted to do that we realized that what the previous group had left us was not configured correctly and was also missing a lot of important code. Upon realizing this, Kurt and I went to work trying to figure out what exactly was missing and preventing the backend from running correctly. This debugging took up a vast majority of the time, and in the end Kurt was able to figure out what the main issues were and managed to get the backend partially running. This was still not enough for us to get our endpoints tested however.

Given that this sprint was more of a challenge than initially expected, there are definitely things that we could have done better as a group in hindsight. One of the bigger mistakes I believe we made was that we didnt have everyone working on the backend problem. Since this was the priority, it should have been a team effort to try to solve it and get it running as fast as possible so that we can test the rest of our code. Unfortunately since in the beginning we didnt realize the scope of the issue we never organized the work in that way. Many of the team members were forced to wait until the backend was complete before they could try to do the tasks that they were assigned. However since the backend never ended up getting fully completed these team members did not have as many opportunities to contribute.

Given hindsight about my performance in this sprint, and knowing what the issues we faced were I can look back and see that there were definitely things I could have done better. One of the main things that comes to mind is my initial approach to trying to solve the backend issue. At first I simply attempted to brute force the problem, moving code and files I thought might be affecting the issue around in the project to see if that changed affected anything. This proved to be a useless exercise in the end and resulted in me wasting more time than I should have. If I could do it again I would approach the issue more slowly, reading through all the relevant code and researching what issues may cause the kinds of problems that we were experiencing.

I do not have any gitlab links to share, since I was unable to get the backend working and therefore had nothing to push. As I mentioned a majority of my work was brute force trial an error where I attempted to figure out the issue.

Sprint 3- Retrospective Blog

For this sprint, my team, team 1, managed to complete all the epics that we had, which were .gitlab-ci.yml, fixing API, modifying backend, finishing frontend, and completing documentation project. I believe my team is done with the API, backend, and frontend. A small portion of the gitlab-ci.yml and the documentation project are still in progress.

In this sprint, I have worked with backend and frontend projects. For the backend, first of all, I modified the API to reduce the number of endpoints from 5 to 2 which getReport and getVesion. Then, to send fake data without using any endpoints, I created a folder named send_Fakedata_RMQ. This folder contains two files, one is used to contain dummy data and the other one is used to create rabbitmq connection and send those dummy data to a rabbitmq channel. So, whenever we use the command of node ./src/send_Fakedata_RMQ/sendData.js, we are sending dummy data to rabbitmq. These data are used to test how the entire backend works. To automatically retrieve those data from rabbitmq and store them into mongodb, in the index file, I added a new method called RabbitMQ_service(). In this method, I used setInterval() function to repeatedly retrieving data from rabbitmq every day. The fixed time used to delay between each call should be converted from day to ms, 86400000.

For the getReport endpoint, I’ve added two new properties called new_household and new_people, which represent the two columns of the Newsince field in the example report. Furthermore, I also edited the csv.js file to make the getReport endpoint return the report in text form instead of downloading it directly to the computer.

For testing, I created two tests for this backend. One is used to test the response status, the other one is used to test the response data. To test the response data, I added a new file called expectedResult.js in the testing/test/lib folder. This file contains a string where each value in this string is manually counted based on dummy data I sent to Rabbitmq. This string is supposed to be my expected result which I am using to compare with the actual result recieved from the system.

One of the problems of the backend is about what should be stored in the guestInfo collection. Since I misunderstood the properties of the guest variable in json, I stored each guest as a unique guest in the collection without the “date” property. The requirement of this collection is that every record of each guest must be stored with a date and time, so this issue must be fixed in order to produce an accurate report in the near future.

For frontend, I added the same folder named send_Fakedata_RMQ from the backend to send dummy data to check whether the frontend is working or not. In getReport.vue, I added a method called downloadCSVfile(data) to download a file named WCFB_report.csv, when the “Submit” button is clicked. I also added a simple instruction of how to run the frontend in README.md. I believed we are done with the frontend and it works fine as expected.

For this sprint, we all focused and worked on different topics to perfect the reporting system as much as possible. Most of the time we worked well as a team, but there were still some points that I think we should improve in the future. Like what I just said, each team member worked on a different topic, so it is hard for us to keep track of all topics at the same time. Team members should actively share the problems they are facing so that the whole team can look at it and help them as soon as possible. Don’t stay silent and wait until the last minute without giving any reason to the team. I mean each team member should be aware of his/her responsibilities to the whole team. On the other hand, for myself, I think I should learn more about teamwork skills to ensure that every team plan is completed by every member before the deadline; or at least I can come up with some solutions to deal with similar situations.

Sprint 3 Retrospective

In our final sprint, our team focused primarily on finishing our demo, communicating with other teams about their projects and how they will fit into the cluster, and creating a schematic of the final cluster. I think our final sprint went really well. While we did not finish everything we set out to, we were able to get a significant amount of work done, and I think we have left the project in a good place for whoever will be picking it up next.

I think a lot of things went well in this sprint. Similar to our second sprint, we had a much clearer understanding of what we wanted to accomplish in this sprint, and that made it much easier to divide work into manageable tasks. Unlike the last sprint, much of this work could happen concurrently, so team members were blocked less often by the issues other team members were working on. Additionally, I think we were all much more comfortable communicating with each other, and this allowed our work to go much more smoothly.

The only thing that didn’t go well was how much work we wound up getting done by the end of the sprint. We initially planned for thirty points of work, and by the time the sprint had officially ended we only got through about half of that. I think we underestimated how long some of our issues would take to complete and wound up falling behind. Regardless, I feel that we got a substantial amount of work done.

Our team worked very well during this sprint, but there is always room for improvement. I think we could improve on our time management a little bit. We spent a lot of time discussing how we would like the sprint to go, and this left less time to actually work on our issues. Still, I don’t think this impacted us too heavily; I am happy with the work we did get done.

Personally, I think I could improve on the way I write documentation, especially summaries of research I’ve done. I tend to get overwhelmed by whatever information I’m reading and will forgo some details in my retelling. I want to be able to write more detailed documentation since that would be more beneficial for my team members.

Contributions:

Research Helm – I spent time looking into Helm, which is a package manager for Kubernetes. I researched what it is, how it works, and whether it would be worth using in the final cluster for Thea’s Food Pantry.

Communicate with Team 1: Inventory System – I informed the Inventory System team about our work, and I made sure we understood how their project is structured.

Communicate with Team 3: Food Keeper – This is similar to the previous issue. I informed the Food Keeper team about our work, and I made sure we understood how their project is structured.

Communicate with Team 4: nest Guest Info – This is similar to the previous two issues. I informed the Nest Guest Info System team about our work, and I made sure we understood how their project is structured.

Sprint 3 Retrospective

(I’m sorry if some sentences are hard to understand. I am pretty sick at the moment, and it’s hard to make sense sometimes)

Our third sprint had two end goals, deploying a demo locally using minikube then hosting it using AWS EKS, and discussing with the other teams on what they’re working on so we can make a schematic from their work in a hosted Kubernetes Cluster. We ended up discussing it with the other teams and were able to create the final schematic. We were also able to deploy a local demo of the Kubernetes Cluster, but we had issues deploying a demo on AWS EKS.

What worked well was discussing with the other teams to get information on how the final schematic would look like, and how our team worked together in organizing the information from talking with the other teams (1). There were also many regards while working on the final project where we came together as a group to set up a schedule, how we’re going to do the presentation, and when we should do it. Afterwards, we were able to use this information to create a schematic illustrating each of the different team’s works inside of a deployed Kubernetes Cluster (2).

I think part of the reason the third sprint was the most difficult was that it was the last sprint in the semester. For example, I and some of my other teammates had a lot of projects we had to get done while due dates were getting close. This made it harder to focus a lot of time on working on the project. Maybe if we focused more time on this project, we would’ve been able to get a demo out, but it isn’t a guarantee that it would’ve happened.

As a team, I think we could’ve been more communicative and dedicated more time to working together on the project. There was a lot of not knowing towards the end on whether or not someone was working on something because communication on some level broke down, especially when some people in the team were busy with other things. This led to troubles with communication, especially when working on the final project. There were times where we agreed to finish work by a certain deadline, but not everyone finished by it.

As an individual, I was constantly trying to push myself to be more active in communication with my team members about updates. However, this does not mean that I was good at it, or I did it without flaws. From my role as a scrum master during this semester, I think that I need a lot more experience in communicating with my team members and being more assertive in initiating conversations and keeping planned dates we agree on in check.

Sprint 3 Retrospective

Our third sprint was definitely the toughest, and we ran into some issues throughout the sprint that really slowed us down. We started out at fixing problems for the project from the end of the previous sprint, then moved on to the last issues we put in the backlog. One issue in particular would take a lot of time to solve and prevented some of the other issues from being completed.

Starting with what worked well, we were doing better at communicating with each other and finished with enough weight for the review. When we were having problems with the issues, we were keeping in touch with each other, and most of us were working together on the main issue that was holding us back. Some of us were having more success than others, but it was eventually completed and the other issues that were relying on it were being finished too. We were also able to finish the presentation on time, and had a plan for putting the presentation together with slides and an outline that we put together.

Our main problem for this sprint wasn’t a problem with the team, but with one of the issues we were working on, which had to do with building the backend server and getting it working for everyone. Along with getting the server working, some of us had different issues that others weren’t getting. We spent a lot of time working on this issue, and had to rush through the last issues in the last week. Aside from that, we were still trying to improving on keeping up the merge requests up to date. We managed to get all the merge requests done in time, the requests would just build up over a few days. Aside from that we had some days where team members would not be there in person, but they would join online and were able to join in the in-person discussions through the discord chat.

I think I did well at continuing with the improvements I was making as a team member by communicating with the team when working on the project and the presentation, but there were a couple times when working on the presentation that I missed out on some discussion. I would later join in the discussions, catch up on what I missed, and do my part in recording for the presentation. When waiting on the backend server issue being completed, I had the idea of setting the api tests up with a template for the test files, so that they would be mostly done by the time we are able to use the api. That way, the issues could still be completed while dealing with the backend server. I got this idea from a template file that we had made in the previous sprint for the data files, and a template file for api testing that was created during this sprint, and figured we could have something similar for the api testing methods while waiting. In the endpoint api templates, the testing methods were set up for the api to accept sample valid and invalid calls that worked for samples we had, so when we would be able to use the api for the testing, we could just make new calls to put in those positions and then adjust based on testing results.

Sprint 3 Retrospective

Our third and final sprint for the semester was our strongest sprint to date. Everyone in the team could feel that we were really hitting our stride and solving issues as they were being created. We were able to look at what went wrong in our prior sprints and not get trapped in the same pitfalls that we encountered early in the project.

The Good

We were laser focused on what we needed to do. Our productivity and communication levels were at an all-time high which really helped in the amount of work we were able to produce. We were also able to realize when an issue was more than a bite-sized problem and successfully broke them up into smaller issues as needed. We had a clearer vision of the direction we wanted to take the application in and for the most part we met the expectation we set for ourselves this sprint: A demo application that highlights its main functionality.

The Bad

I mean… There wasn’t too much that really went wrong with our workflow during this sprint. I think the feeling that we performed very well was very tangible to anyone watching us operate as a team or looking at our team’s activity on the project repository. The only bad thing that would come as a result of this sprint is that we are concluding our work on our application that we witnessed grow from inception.

What could we have done better?

I feel like the only thing we could’ve done better was perhaps having a longer discussion on how we envision the app to look in the future. Leaving better instructions for the next team of students who will work on this project is the only thing that comes to mind when I think about anything we might have lacked in.

Contributions that I added to the application include

Writing Portion:

Create a writing page for an examinee to record the prompt they heard from the proctor. They will type out what they heard instead of using their finger or a stylus to write it out. The current version of this feature is a temporary solution until a way to implement the correct functionality is discovered.

Create a page that holds all the prompts the test proctor will ask the examinee to write(type) in English. A .csv file named “sentences” was added into the projects assets folder. The Prompts.js file reads from and parses the sentences from the file into a list which is then displayed in a ScrollView on the page.

Adding React Native Paper styling to Writing and Prompt pages. We decided to use React Native Paper styles throughout our application. In order to remain consistent with the application design, I added card features for the elements on each page.

Merging of Writing page and Prompt pages. After the pages were created a teammate suggested that we merge the pages instead of having to navigate too much. This was a great idea because it was much easier to implement than having to move from page to page as well as improving the UI.

Reading portion:

While working on my own issues, I aided my teammates in working with our app’s counterpart to the writing portion. The bug we encountered involved displaying a question from a list of questions on a separate page. While we couldn’t resolve the bug itself, we were able to verify that it is possible to display another question successfully on a “new page” but do not have the means to display the correct one at the moment.
