White box testing is software testing in which the pieces of software’s internal structure are tested, including its design and codes. It improves design and security while also checking the input-output flow. The alternative term for white box testing is clear box testing, as it is characterized by code that is readily accessible and readily discernible, in contrast to black box testing
White box testing is also called open box testing, transparent box testing, glass testing, and code-based testing. Using white box testing, the tester can check if there are any security problems, if the code is well-organized, how the code works, checking loops, and checking each part individually.
How to perform White Box Testing?
During white box testing, the steps are as follows.
Identify the program, feature, or component that requires testing
The smaller your target system part, the better it is for white box testing. Testing each feature on its own lets you focus on a small chunk of code, which is what we’re trying to accomplish: test all possible scenarios and scenarios for a particular feature. You should start with the smallest logical part of the system and then move on to the next one.
Draw all potential routes in a flowchart
This stage is the most important stage of your test planning and execution of the White box strategy. It’s important to know the scope of any project, whether it’s development or testing. Moreover, path coverage provides a comprehensive solution to test coverage.
In this section, you are attempting to understand each testable path for a specific feature, component, or module. The process of creating test cases that encompass all of the various pathways can be facilitated by identifying them. You can create a flow diagram to illustrate the desired pathways.
Create test cases that address each step in the flowchart
You can write test cases to look at each alternative path on the flowgraph after you’ve shown them all. The testing phase can commence when you have a large number of test scenarios that you’re confident will cover every possible route.
Implementations of components
Testers will use the projects they made and do regular tests for producers. They will mix and combine different ideas from other people and let users talk to each other.
Implement, then repeat
After identifying the system, component, or module, it is possible to commence the White box testing process. Furthermore, you possess the necessary flowchart and test cases to conclude the testing process. That’s how you can handle White box testing.
Advantages and Disadvantages of White Box Testing
Advantages of White Box Testing
- Test cases are easily automated.
- The tests can be carried out without the use of a user interface.
- Testing is more efficient than other methods.
- The code can be optimized as the undetected errors are revealed.
Disadvantages of White Box Testing
- It is, however, a more complex process.
- It can be quite expensive.
- The tests are typically lacking in detail, which may result in errors.
- Testing requires technical knowledge and an experienced resource person is required.
