test-driven-development

Star

Test-driven development (TDD) is a software development process relying on software requirements being converted to test cases before software is fully developed, and tracking all software development by repeatedly testing the software against all test cases. This is as opposed to software being developed first and test cases created later. Programmers also apply the concept to improving and debugging legacy code developed with older techniques.

Process

Add a test

Run all tests. The new test should fail for expected reasons

Write the simplest code that passes the new test

All tests should now pass

Refactor as needed, using tests after each refactor to ensure that functionality is preserved

Repeat.
