Transcript

  • 1. Test-Driven Development
    • What is Test-Driven Development?
    • Origins of TDD
    • Clean code with no defects
    • TDD in conjunction with Agile
  • 2. Why TDD ?
    • Much less time needed to debug
    • Code proven to meet requirements
    • Quick feedback at each step
    • Rhythm of Success
  • 3. Mechanics of TDD
    • Start with a failing test
    • Write the simplest code needed to pass the test
    • Remove duplication ( Refactor )
    • Repeat as needed to meet requirements
    RED GREEN REFACTOR
  • 4. What should be tested?
    • Valid inputs
    • Invalid inputs
    • Errors, exceptions, and events
    • Boundary conditions
    • Everything that could possibly break!
  • 5. TDD as a Design Technique
    • Design only what you need to make the test pass
    • Requirements drive the design of code
    • Design evolves with time
  • 6. Fixing Bugs – TDD Style
    • Go after the most painful defect
    • Write a test to expose it
    • Write code needed to fix it
    • Refactor
    • Measure the results
  • 7. TDD Benefits for Business
    • Shorter development cycles
    • Near zero defects
    • Tests become an asset
    • Tests are documentation
    • Competitive advantage!
  • 8.
    • Get some training
    • Start with a small visible project
    • Shoot for 100% test coverage
    • Don’t expect to be perfect
    • Expect to improve dramatically in time
    • Measure the results
    Getting started with TDD
  • 9. Test-Driven Development TDD Demonstration
