What Are the Differences Between Unit Testing and White Box Testing?

Unit Testing

  • In the software development life cycle, unit testing plays a key role in delivering a bug-free application. During the coding phase, an application is built step-by-step and each step is considered a unit.
  • The developer tests each unit/component to make sure it's working as expected - this process is referred to as unit testing.
  • Unit testing is the very first type of testing performed on the code as it is developed.
  • It allows the developer to identify and fix the majority of bugs in the early phase of SDLC where it is easy to identify and fix bugs.
Unit Testing Techniques:
  • Black Box Testing
  • White Box Testing
  • Gray Box Testing

White Box Testing

  • In White Box Testing, a QA engineer tests the structure of the application to enhance its design, inner working, and security.
  • The tester must have knowledge of the programming language used to build the application.
  • The source code is visible to the tester, which is why it's also known as Clear box testing or transparent box testing.
  • It is more complex as compare to Unit testing.
White Box Testing Techniques:
  • Unit Testing
  • Static Analysis
  • Dynamic Analysis
  • Statement Coverage
  • Branch Testing Coverage
  • Mutation Testing
