Test Driven Development (TDD)

Test Driven Development (TDD)

1. Is a software development practice that focuses on creating unit test cases before developing the actual code,the primary intention of this technique is to modify or write new code only if the tests fail.This has three phases of Test Driven Development

   • First:Create precise tests
     • It must be ensured ensure that the test compiles so that it can execute.
   • Second:Correcting the Code
     • if there are errors developers need to make the minimal changes required to correct the code
   • Third:Refactor the Code
     • Check for redundancy or any possible code optimizations to enhance general performance. Ensure that refactoring does not affect the external behavior of the program.
