Black Box Testing

Black Box Testing

1. Advantages

   • Can help identify where the user requirements are not being met.
   • Testers do not need to know about the code and so the tester can be independent of the developer.
   • Test cases can be designed as soon as the specification for the unit is completed.

2. Disadvantages

   • Not all program pathways are tested as only a small number of input cases are used.
   • Repetition of tests already carried out by the programmer may occur.
   • The reason for a test failure cannot be determined.
