Unit Testing refers to part of SDLC cycle which involves thorough testing of an individual and smallest part of a software program.

• The basic objective of Unit level testing is to evaluate how individual units would contribute to achievement of overall objective of the software.

• This level of testing is carried out by isolating the unit to be tested meaning the code is tested independent of the whole software.

• Unit Testing is usually performed by one or more developers either manually or by using an automated software solution.

• Unit Testing is a very significant step in early determination and fixing of errors and bugs in the code. Comprehensive Unit Testing eventually leads to favorable results, at the end of the SDLC cycle ensuring a zero defect software.
