Questions and Answers

What is the main difference between Black Box Testing and White Box Testing?

  • Implementation of code is necessary for Black Box Testing, but not for White Box Testing. (correct)
  • White Box Testing is an external software testing, while Black Box Testing is an internal software testing.
  • Black Box Testing is done by software developers, while White Box Testing is done by software testers.
  • Knowledge of implementation is required for Black Box Testing, but not for White Box Testing.
