In software development industry the most crucial stage or phase is software testing. After coding phase or stage testing phase starts. Testing uncover the faults in coding phase. There are broadly two types of testing techniques under which all testing concern they are white box and black box testing. In white box tester has full knowledge of codes and their functionality while in black box testing testers have only knowledge of input and corresponding output. Testers carefully design test cases so that they can analyze all functionality. Black box testing analyze functional requirement in the software.
