A Complete Guide to White Box Testing

White Box Testing – Definition:

White box testing means the software testing in which the internal structure of the software is tested including the Design and codes is known as white box testing. It improves the architecture and security of the system while also ensuring that the input-output flow is correct. White box testing is also known as clear box testing because it unlike black box testing the code is available and visible.

There are many name of the white box testing like open box testing, transparent box testing, glass testing, and code-based testing. With the help of white box testing the tester can find or not but there are any security loopholes, if the codes are perfectly structured then the input flow in the code and checking conditional loops and testing every elements individually.

How to do White Box Testing?

Steps of white box testing:

– Identifying what has to be tested
– Plotting on the flow graph
– Creating test cases for every path
– Execute

1. Identifying What has to be tested

If the elements of the identified are smaller in the numerical then it is better as a white box testing endorses testing every components of the selected cases. When these are put to the test, all of the flaws become apparent. The features and components are tested on a regular basis to guarantee that they function as planned. Small partials are tested and when the goal is achieved then the next component is taken. It’s also critical that the tests are energy efficient, meaning that the quantity of energy expended is proportional to the amount of output produced.

2. Plotting on the flow graph

All the possible and thinkable ways are plotted into the flow graph. These paths can be used for any feature, component, or module. It’s useful for the scope of the testing.

3. Creating test cases for every paths

After the plotting the possible paths can be create and do test case for each path. After the test cases are done then they will be executed.

4. Execute

Execute is the step of exestuation testing where the test cases are executed. Execution phases can be repeated for the confirmation of the test results.

Types of White Box Testing

– Unit Testing
– Static Analysis
– Dynamic Analysis
– Statement Coverage
– Branch Testing Coverage

1. Unit Testing

This function is used to do conformation whether a particular code is running or not and to check its functionality too. Unit testing is done in the early steps of the process. Unit testing is one of the fundamental elements in the performance process because it helps to eliminate trivial errors.

2. Static Analysis

It is used for calculating the static parts of the code. If there are any defects of error occurs then the static analysis will help to figure out. That’s why the errors will be removed into the first step of the process only.

3. Dynamic Analysis

Dynamic analysis comes after static analysis. After so many testing the conclusion comes that static and dynamic analysis should be performed together. The source code is evaluated and then executed with the help of dynamic analysis. The output is evaluated, but the process is unaffected.

4. Statement Coverage

The most important step of testing process is known as statement coverage. The advantages are obtained into the step of execution. The statement coverage will help to analyze whether the functionalities are in working order or not. Every function will be executed even if it is for once.

5. Branch Testing Coverage

The software and online applications aren’t all programmed in the same way. They are divided into various groups in order to facilitate the sorting procedure. Branch testing coverage helps to find out the fast result. The branches are verified through codes. If there is any unnatural elements found into the application then it can captured easily with the help of this code.

6. Security testing

Security is the element which needs to be perfect all the times. So security testing is done by most of the testers. The application must be automatically protected, which necessitates the creation of a process. There are many sub steps of security testing. If there is any unauthorized access, testing aids in the correction of the problem. If a breach is possible, the method blocks it.

7. Mutation Testing

Mutation testing is the last step of the process. Basically it is a rechecking technique to find out the errors and defects that will help in obtaining more information about the strategy to make the system stronger at regular intervals of time.

White Box Testing Tools

• HTML Unit
• CPP Unit
• PY Unit
• Ecl Emma

Advantages of White Box Testing

• The tests can be carried out without the use of a graphical user interface.
• The test scenarios are simple to automate.
• It is more efficient to test.
• Code optimization can be done as the hidden errors are visible.

Disadvantages of White Box Testing

• It is so expensive.
• Comparatively it is more complex process.
• The testes are not in detailed; hence they can have errors.
• As an experienced resource person is required for testing because it requires technical knowledge.
