Chapter 2: Testing Throughout the Software Development Lifecycle

Which of the following accurately describes a test-first approach?

  • A Tests are derived from acceptance criteria and run to check that the code passes these tests
  • B Application behaviour is written in Given/When/Then format and tests are then written and run
  • C First the tests fail then the code is written to pass the tests and this is iterated
  • D Code is refactored first then tests are written and run
Explanation

A test-first approach begins by creating a failing test, then implementing code that makes the test pass, and repeating this cycle. Refactoring may follow once the tests pass.
