Unit Testing

  • In the software development life cycle, unit testing plays a key role in delivering a bug-free application. During the coding phase, an application is built step-by-step and each step is considered a unit.
  • The developer tests each unit/component to make sure it's working as expected - this process is referred to as unit testing.
  • Unit testing is the very first type of testing performed on the code as it is developed.
  • It allows the developer to identify and fix the majority of bugs in the early phase of SDLC where it is easy to identify and fix bugs.
