White Box Testing minutely verifies whether the program can be successfully executed with other parts of the application.

White Box Testing

What is White Box Testing?

The White Box Testing is a category of testing strategy that mainly evaluates program structure and derives test data based on program logic or code. It moreover cited names like clear box testing, open box testing, logic-driven testing or path-driven testing, or structural testing.

White box testing, likewise known as structural testing or code-based testing, is a process that ensures and validates a software application’s tools, internal framework, and objects and elements. This method of testing not just ascertains a code as per the design specifications but moreover uncovers an application’s weaknesses.

During the white box testing stage, a code is run with preselected input values to assess the preselected output values. If a mismatch is found, it suggests that the software application is damaged by a bug. This procedure moreover involves writing software code stubs and drivers.

Synopsis of the White Box Software Testing Method

Applicable at the unit, integration, and system phases of a software testing phase, the procedure of white-box software testing an app on the source code phase. The test cases developed as a result of this testing strategy are based on design methods like control flow testing, branch testing, path testing, statement coverage, and decision coverage.
This technique of testing is one of the best procedures to discover errors in the early stages of software development. By following this procedure, one can test paths within and between units, and between sub-systems when the system-level test is being maintained.

How Does White Box Testing Work?

The steps to execute this Testing in a specific order –

Firstly all characteristics, elements, and programs to be tested, specified first.
Develop a flow graph and identify /plot all possible paths in the flow graph.
Identification of all reasonable paths from the flow graph.
Write test cases for every sole path of the flow path.
Implement, rinse and repeat test cases.

Benefits of White Box Testing

The benefits of this testing elucidated in the following manner –

Required understanding of the internals of the software under test to be tested.
It enables a finding of unknown errors, to discover internal errors because it tests and works by internal functionality.
It assists to discover problems and optimize code to adopt various strategies of White Box Testing to test a developed application or website.
It needs internal knowledge to do testing that’s why it boosts in maximum coverage of the code.

Why White Box Testing Matters?

White Box Testing is crucial because it helps to test the following –

It is implemented at various levels such as system, integration, and unit level of software development.
One major objective of White Box Testing is to ascertain the working of an application.
It involves the identification of the functional flow of an application.
The functionality of conditional loops.
Testing each statement.
Testing of each object.
Testing of the process individually.
Detection of Internal Security holes.
Irregular or incorrectly structured paths in a coding procedure.
The flow of particular inputs through a code.
It is implemented at early stages and does not wait for GUI(Graphical User Interface) availability.
Testing is done in such a manner that it covers most of the paths.

What is Assessed in White Box Testing?

Security holes, broken or vague paths, and conditional loops in a code
The progression of structure spoken of in the specification document
Scheduled outputs
Line by line or section by section in a code
Each statement, object, and function is assessed separately

Conclusion -

White Box or clear box testing is the one where the inner structure and elements of the application are disclosed to the tester. In this blog, I have talked over White Box testing and its procedures in detail, you can refer to them before we get to the advantages and drawbacks of white box testing.

The software developer does a bit of glass testing at his end too while executing unit testing. A software tester, who needs to execute this testing, needs to have good proficiency in the coding language and logic to be productive.
