Software Testing

The choice of test approach is one of the most necessary factors in the success of the test efforts and the correctness of the test strategy. This factor totally depends on the tester and test leaders. The main focal point of this testing is to evaluate functional and end-user requirements.

There are various levels in testing which are given below:

• UNIT TESTING- The unit testing is the level of testing where every module of the component is tested to verify if they are fit for use.
• INTEGRATION TESTING- The integration testing is the level of testing in which interface between the two or more than two modules is tested.
• SYSTEM TESTING- System testing is the testing of the software application module as a whole to determine whether the software is compliant with the user requirement or not. It is an end to end user perspective testing to find flaws in the software.
• USER ACCEPTANCE TESTING- It is the software testing process where the whole software is tested for acceptability and validates the end-user requirements. This level of testing is executed by the client in a separate environment and checks that the software fulfilled the requirements or not.

In software testing, there are many kinds of testing methods which are described below:

•  BLACK-BOX TESTING- Black box testing is the method of testing in which software is tested without knowing the internal structure of the program/code.
• WHITE-BOX TESTING- White box testing is the method of testing in which internal structure is completely known to software tester.

Test approach 

A test approach is the test plan operation of a project that defines how testing would be done. Test approach can be of two types:

• PROACTIVE- An approach in which the test plan is create as to find the flaws and fix them before the application is created.
• REACTIVE- An approach in which testing is not started until after the coding is completed.
• GRAY-BOX TESTNG- This method of testing is basically the effective combination of the both white box and black-box testing. This method of testing provides a great way to test the software application.
• AGILE TESTING- This method of testing involves testing from the end-user requirement and performed as early as possible.
• ADHOC TESTING- This method of testing begins with learning applications first and then work with the actual testing. This testing is all about the perfection of the testing.

Some essential software testing steps that every software engineer should perform before showing to someone else:

1. Basic functionality testing- The basic focus here is this you do not let the second party touch your work if it’s going to crash soon as they enter their username into the username field. If your basic functionality testing detects something is not working then it’s totally fine.

2. Code review- If your coding methodology requires review so perform this first before you hand the code for the testing process.

3. Static code analysis- There are some tools that can be used to perform analysis on source code without executing it.

4. Unit testing- Tester should also work with individual components and virtualized services to make sure that their individual component unit can work properly.
