Presentation Transcript

  1. Advanced Testing Techniques on Force.com Paul Battisson

  2. Introduction • Paul Battisson (@pbattisson) • Xactium • What? • Mocking • Stubbing • Patterns • Next steps • Why? • Improve testability • Improve flexibility • Work faster

  3. 3 Types of Test acceptance integration unit

  4. What's Wrong With Force.com Testing? • "Slow" to write • "Slow" to run • Brittle • High data dependence • Written badly • Coded badly - highly coupled • Lots of testing of DML

  5. More Interfaces • Code against interfaces • Plug sockets (@simongoodyear) • Immediate improvement in flexibility and testability

  6. Mock Objects • Implement the same interface • Used in place for a test • Assertions on how we expect the object to be called • Can contain stubs for flow • Allow us to test our object's interaction with its neighbours

  7. Stubbing • Simulate real behaviour to get a test to pass • Implement in a mock object or using isRunningTest()*

  8. Okay, so what?

  9. Test Isolation

  10. Less Test Data Setup Insert a Record Required Fields? Instantiate a Mock Validation Rules? Before Trigger After Trigger

  11. The Future Dependency Injection Metaprogramming Frameworks & Patterns

  12. Thanks • Matthew Botos (@BotosCloud) • Simon Goodyear (@simongoodyear)
