Testing with FIRST principles

Link: here

The FIRST principles of testing stand for:

  • FAST - tests should run fast, slow tests are a deterrent to developers running them.
  • Isolated/Independent - tests should have no external dependencies
  • Repeatable - you should be able to run a test over and over again, no state outside the test is affected
  • Self-validating - the outcome of the test is asserted inside the test
  • Thorough - assertions are appropriate and complete
