Advantages and Disadvantages of Black box Testing :

Disadvantages of Black box Testing

Advantages :
  • Tests are done from a user’s point of view and will help in exposing discrepancies in the specifications
  • Tester need not know programming languages or how the software has been implemented
  • Tests can be conducted by a body independent from the developers, allowing for an objective perspective and the avoidance of developer-bias
  • Test cases can be designed as soon as the specifications are complete

Disadvantages :
  • Only a small number of possible inputs can be tested and many program paths will be left untested
  • Without clear specifications, which is the situation in many projects, test cases will be difficult to design
  • Tests can be redundant if the software designer/ developer has already run a test case.
  • Ever wondered why a soothsayer closes the eyes when foretelling events? So is almost the case in Black Box Testing.
