Sprint 2 Retrospective

 Links to evidence of activity on GitLab.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/generatewcfbreportfrontend

I created a new generate WCFB report frontend which I used the sample frontend example from the professor. I have already had a basic model for the Frontend. I need to do more to connect the backend API, which can let customers download the report for the inventory.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/23

I designed the API for backend endpoints.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/34

I met with Marcos and Matt and talked about the difference between each group’s FrontEnd design. For the next sprint, we will be having more meetings to help each other out on the API.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/35

I looked for WSU visual standards to use for the frontends.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/61

As a team, we created a Docker_compose file for the Integration of all systems.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/67

I implemented FrontEnd for Reporting with the most recent version

I am researching Kubernetes with Migena.

We are reviewing Scrum issue boards

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/12

We are reviewing LibreFoodPantry Architecture and technologies used.

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/community/-/issues/58

I am creating a simple frontend to test keycloack with Migena.

Reflection on what worked well?

In terms of what worked well, team members are working together more efficiently to complete the project plan through the first phase of working together than ever before. After a teamwork period, we have a deeper understanding of our mission goals and become more accustomed to each other’s habits. There will be a relaxed working atmosphere, and the chemistry between the groups will encourage each other to move the project forward.

Reflection on what didn’t work well?

As for why it didn’t work out, there was some confusion about the final product as to the project’s future goals. When faced with unknown challenges, we are still a little confused. As we communicated with the professor, we had some clear goals. Because the front end and the back end are related, taking charge of every task affects productivity. So we have overlapping project leaders working together to get the job done, which improves efficiency. The mission was complex and challenging, but we encouraged each other through the ZOOM meetings after class.

Reflection on what changes could be made to improve as a team?

As a team with cooperation, smooth communication, and tacit understanding among team members are the basis and key to improving our team’s cooperation level. We would discuss the project after class and give some constructive suggestions about each other’s tasks. Good communication makes our team have chemistry. Through communication and cooperation, we have a thorough understanding of the team members’ tasks. Each knew the other’s project progress would be conducive to the overall advancement of the project. When a team member encounters a bottleneck in a task, we will appropriately slow down the overall progress and communicate with him to buffer his time to complete and push forward the overall task progress.

Reflection on what changes could be made to improve as an individual?

As an individual, I need to improve my understanding of the Frontend more quickly to help my team better connect Frontend and backend. I need to arrange my group tasks more reasonably to help promote the whole group project’s completion. Besides, I also need to make clear my work objectives, continue to follow up on the team’s project, and make my part and the whole develop simultaneously.

Breakable Toys

 We can all benefit from writing random “toy” programs to push ourselves to the limit by setting artificial limits. — Donald Knuth, The Art of Computer Programming

If you can learn as much from failure as you can from success, you need a relatively private space to look for the loss. In balling acrobatics, a performer who tosses three balls will never progress if he has never tossed five. Those who spend hours picking dropped balls until their back hurts eventually get good at it. The same lesson applies to software, where software workers often need to step out of their comfort zone to try something they’re not good at it. It is by taking bold chances again and again that you improve your skills, that you learn and grow from failure after failure. Just as a three-ball-tossing performer does not throw five balls in a formal performance, software developers often make mistakes in new areas. Software developers also need a safe place to make mistakes. It’s terrible not to have such a safe place to make mistakes. The fear and unwillingness of software developers to make mistakes make them stuck in a rut, unable to learn from failure, and thus makes the entire software development industry staid and stagnant.

Other examples of the “crunchy toy” pattern include games like Tetris and Tic-Tac-Toe. One senior I know has a habit of using every new language he learns to create a game, blog software, and IRC client. The nature of the problem is to build a toy that contains learning something new and provides an opportunity to let you in a special environment to deepen the understanding of hand tools. The environment is not only safe because you are the only or most influential users, and, even to the most powerful commercial products, you still have room to serve you as a user’s needs better.

You still have to remember that they’re just toys, and that’s why they’re supposed to be fun. If they’re not interesting, then when the initial excitement is over, they’ll just become a dusty relic, and you’ll be able to focus your energy on what you enjoy building.

DD path graphs

Structural testing is based on the source code of the program under test, rather than the definition. This is known as white box testing, while functional testing is known as black-box testing.

Program diagram: For a program written in an imperative programming language, the program diagram is a directed graph with nodes representing statement fragments and edges representing control flow.

DD – path

DD path: Decision-to-decision path (Miller). Begin with the “exit” of the decision statement and end with the “path” of the next decision statement.

DD chain: A path of starting and ending nodes at different points in a directed graph.

Consisting of a node, the internality =0;

Consisting of a node, externality =0;

Consisting of a node, the inner degree > =2 or the outer degree > =2;

Consisting of a node, the degree inside =1 and the degree outside =1;

Length > =1 for maximum drill

DD – path graph

A DD-path graph is a labeled directed graph in which nodes represent the DD Path of a program graph and edges represent the control flow of the Path.

For a given program, many different program diagrams can be constructed, all of which can be reduced to a unique DD-path diagram.

It is possible to generate DD paths for programs up to 100 lines, and above that size, analysis tools are generally required.

The simplest control flow diagram is the DD path. DD can be thought of as belonging to the control flow diagram.

DD path definition:

Given a program written in an imperative language, its DD path graph is a directed graph, where nodes represent the DD paths of its program graph and edges represent the control flow between successive DD paths.

In fact, the DD path graph is a compressed graph in which 2-connected components are compressed into a single node corresponding to the 5DD path.

Be the Worst

There is a saying in China: Better be the tail of a lion than a fox’s head! There is another saying: Better be the head of a chicken than the tail of a phoenix.

 

Surround yourself with developers who are better than you. Find a more robust team where you can be the weakest member and have room to grow. In the beginning, you may not feel confident in your life, but the process of developing and learning in the workplace that makes you stronger is lovely. In this society, no one will care how beautiful and challenging your strategy is. The most important thing is the result. Have you grown and become stronger during this period of enduring learning?

Remember, the probability of being rejected or thought strange by a potential mentor is not high, and the potential payoff is enormous. Even if the person isn’t interested in taking you on as a full-time apprentice, asking her out to lunch can be a valuable investment of time and money, like why dinner with Warren Buffett was auctioned off at such a high price. An early-stage businessman, or an established businessman who has achieved success in a particular field, is all vying for this opportunity. Do they care about the meal? No, they need to learn something from talking to Buffett. Such as looking at the market, investment vision, and the future development trend of business. In computer learning, the principle is the same. By talking with the people above us or the successful people, we can get the information and direction beneficial to our future development. Opportunities are for those prepared, and the accumulation of experience and insight in life will make you soar when opportunities come.

Ask lots of questions.

Tasks such as maintaining build systems, product support, responding to maintenance requirements, bug fixes, code reviews, eliminating technical debt, creating project wikis, updating documentation, acting as a sounding board for other people’s ideas, and so on. Typically, you focus on the less risky edges of the system rather than the core, which often has many dependencies and a lot of complexity. Jean Lave and Etienne Wenger look at apprenticeships in different industries and find that “in the workflow, the tasks of a novitiate are often placed at the end of a branch, rather than in the middle of a series of clips of work” (Situational Learning, p. 110). These fringe tasks benefit the team and you as an apprentice, as they are often skipped in school classes and fill in the gaps. The experience still helps when you become a skilled worker because many of your mentors understand how important it is to do the tedious work. After all, if no one cleans the floor, the team can’t do the glamorous work because it is Mired in a mess.

What’s the most grubby task your team has been putting off for months? It should be the one that everyone complains about, and nobody wants to fix. You solve it. Don’t hold your nose and force yourself to do it; See if you can solve the problem creatively in a way that exceeds people’s expectations and is fun for you. Many people feel that this is a job that is not worth their time. If you don’t do well, you will help the team take the blame. If you do well, the team will take the credit. But you grow as you solve what the team can’t do.

The difference between Stubs and Mocks

A mock is an object that can set an expected value, which will verify that the desired action has occurred. The stub is the object that you pass to the code under test. You can set expectations on it to work in specific ways, but those expectations are never verified. The stub’s properties will automatically behave as standard properties, and you cannot set expectations on them.

If you want to verify the code’s behavior under test, a simulation with appropriate expectations is used and validated. If you’re going to pass only values that might need to work somehow but are not the focus of the test, you can use stubs.

Important note: Stubs will never cause a test to fail. 

I believe the most significant difference is that you have written the stub with predetermined behavior. Thus, you will have a class that implements the dependencies that you have disguised for testing purposes (most likely an abstract class or interface), and a class will handle the method only through the response that is set. They don’t do anything fancy, and you’ve already written stub code for them outside of testing.

Simulations are expectations that stubs must set during testing. The simulation is not set up in a predetermined way, so you have the code to perform the simulation in your tests. The mockery is determined at run time because the code that sets expectations must be run before they do anything.

The difference between stubs and stubs

Tests written with simulation usually follow a test pattern of initialize-> set expectations -> exercise -> verify. The pre-written stub will be followed by an initialize-> exercise-> verify.

Similarities between stubs and stubs

The purpose of both is to remove all dependencies from testing a class or function so that your tests are more focused and straightforward when trying to prove it.

The most crucial difference between Stubs and Mocks is their intention. Explain this in the WHY stub and WHY simulation below

Suppose I’m writing test code for the Mac Twitter client’s public timeline controller

Here is the sample code for the test:

twitter_api.stub(:public_timeline).and_return(public_timeline_array)

client_ui.should_receive(:insert_timeline_above).with(public_timeline_array)

controller.refresh_public_timeline

Stub: The network connection to the Twitter API is very slow, which makes my tests slow. We knew it would return the timeline, so we made a stub that simulated the HTTP Twitter API so that our test could sprint, even if I were offline.


Mock: We haven’t written any UI methods yet, and I’m not sure what we need to register for UI objects. We wanted to write test code to see how my controller would work with UI objects.

In short, there is a difference between Mock and Stub objects, and RhinoMocks recognize that they allow us to write tests that better illustrate their purpose. The mock object is used to define the expectation that, in this case, I want to call the method A () with such an argument. Record and verify this expectation with ridicule. On the other hand, Stubs have a different purpose: they do not record or validate expectations but rather allow us to “replace” the behavior and state of “fake” objects to take advantage of test scenarios.
