This can help to ensure that all execution paths are functional, efficient, and necessary.īlack Box vs White Box vs Gray Box Testingīlack box, white box, and gray boxes are three approaches to testing. Path coverage testing ensures that every execution path through an application is covered by use cases.

This ensures that even little-used code paths are properly validated. Branch coverage testing ensures that every branch within an application is covered by unit testing. Branch Coverage: Conditional statements create branches within an application’s execution code as different inputs can follow different execution paths.Identifying this dead code enables developers to fix incorrect conditional statements or remove redundant code to improve application performance and security. Statement coverage testing can help to identify if portions of the code are unused or unreachable, which can be caused by programming errors, updates, etc. Statement Coverage: Statement coverage testing ensures that every line of code within an application is tested by at least one test case.

To achieve full code coverage, white box testing can use the following techniques: One of the main advantages of white box testing is that it makes it possible to ensure that every aspect of an application is tested.

Data Flow Testing: Tracks variables throughout the execution paths of a program to ensure that variables are declared, initialized, used, and properly manipulated.Loop Testing: Tests the loops within an application to ensure that they are correct, efficient, and properly manage the variables within their scope.Security Testing: Static code analysis and other white box testing techniques are used to identify potential vulnerabilities within an application and validate that it follows secure development best practices.Output Validation: This enumerates the various potential inputs to a function and ensures that each produces the expected result.Path Checking: White box testing can be used to explore the various execution paths within an application to ensure that all conditional statements are correct, necessary, and efficient.Examples of tests that might be performed during white box testing include: White box testing takes advantage of extensive knowledge of an application’s internals to develop highly-targeted test cases.
