Levels of testing (Week 8)

There are
different levels in a testing  process. Levels of testing include different methodologies which can be used during
the process of software testing. There are two main levels of testing :
functional testing and non-functional testing. One of my
previews posts talks about black-box testing, functional testing
is a type of black-box testing which is based on the specifications of the
software that has to be tested. The software can be tested by providing input
and then the results are examined in order to conform to the functionality
which it was meant for. Functional testing of a software is conducted on a
complete, integrated system to evaluate the system’s compliance with its
specified requirements. 
Functional testing includes five steps : 
Step 1 The
determination of the functionality that the intended application is intended to perform.
Step 2 The
creation of test data based on the specifications of the application.
Step 3 The
output based on the test data and the specifications of the application.
Step 4 The
writing of test scenarios and the execution of test cases.
Step 5 The
comparison of actual and expected results based on the executed test cases.
In order to have an effective testing process
all the above steps have to be followed and applied to the testing
policies of every organization for this reason it will make sure that the
organization maintains the strictest of standards when it comes to software
quality. This part is about testing an application from its non-functional
attributes. Non-functional testing includes testing a software from the
requirements which are nonfunctional.  Performance, Security, User
interface are some requirements examples of non-functional testing. Performance
testing is one important and mandatory testing type in terms of the following: Speed, Capacity, Stability and Scalability. Performance
testing can be either qualitative or quantitative. Security testing includes
testing a software in order to identify any gaps from security.


Security testing should ensure the below list of features: 

Confidentiality, Integrity, Authentication, Availability, Authorization, Non-repudiation, Software
data is secure, Software is according to all security
regulations, Input checking and validation, SQL insertion
attacks, Injection flaws, Session management issues, Cross-site
scripting attacks, Buffer overflows vulnerabilities and Directory
traversal attacks.
The levels of testing are important because in order to meet the functional and technical specifications  we have to follow all the steps and features that I listed above.

Hack More!

I read an article this week about which programming language hackers use (http://www.softwaretestingclub.com/profiles/blogs/which-programming-language-do-hackers-use) and while at first, I didn’t see the relationship between hacking and software testing, I came to realize that they have a good amount of similarities. Thinking more in depth about it, the act of hacking is just finding vulnerabilities in a software or program which is the same objective as QA testers (although the intents may be different).

Something interesting about the article was that when asked, “what programming language do hackers use”, the answer given by an expert hacker Adrian Lamo was totally not what I was expecting. He responded that he does not use a programming language which caught me off-guard because I didn’t think it was even possible to hack / test without the use of a programming language. The most memorable and significant piece of information I got out of this article was when Adrian Lamo further explains his answer by saying that its more important to learn how to read code rather than learning how to code. By learning how to efficiently read code, you can dissect how programmers think, what their tendencies are, and what common mistakes they make which can give you a better idea of what to test.

Mocking

The purpose of a unit test is to verify an assumption about the behavior of a software system. And unit tests must be automated so that any assumptions can be verified quickly.

A unit test should also exhibit the following characteristics:

  1. It should have fast test execution.
  2. A test should not depend on database access or any long running tasks. A test should isolate external dependencies.

 

A Mock Object is an object that substitutes for a real object. Mock objects are simulated objects that mimic the behavior of real objects. Mock objects allow you to set up test scenarios without using large resources like databases. Instead of calling a database for testing, you can simulate your database using a mock object in your unit tests. This makes tests run faster.

Can test automation replace human testers (Week 7)

This article lists the pros and cons for test automation  and human testers.  This days the IT managers and directors are in dilemma because they have to decide what is better for their department to use for software testing the automated testing or the manual testing. Do they have to hire a team of software testers or would they be better using automated testing? These strategies have big difference. Both these strategies have pros and cons here are some:

Automated Testing

Pros: The main advantage of using automated testing is the speed, IT managers can use this strategy to test the code faster then manual testing and also they can re-use the automated testing tool many times that they need. Automated testing can be used ion different operating systems. It is very effective for build verification and testing.

Cons: A down side of automation testing is not helpful with UI testing, it can not be trusted all the time also it has high initial cost of tools.

Manual Testing

Pros: Manual Testing is the testing of software for bugs in the software system. Testers execute test cases without using any automation tools. Lets talk about some of the pros, companies that can’t afford automated test tools can use testers to write and execute test cases, this strategy is flexible compared to automation testing.

Cons: Manual testing can be very slow compared to automation testing. The tester have to be engaged 100% with the software and has to know the structure of it. If the tester don’t know the structure of the software can be a high chance of missing out on some bugs.
