1. ( ) Unit Testing with MXUnit
2. ( ) (A really gentle introduction)
3. ) (
4. ) (
5. ) ( Prove to me that it works
6. ( ) Unit vs. Integration Testing ⊛ Small units vs. sequences ⊛ MXUnit vs. Selenium
7. ) (
8. ( ) ⊛ Write test code that fails ⊛ Make the test work ⊛ Refactor/refine
9. ( ) MXUnit http://www.mxunit.org/
10. ( ) MXUnit Test Runner for Eclipse
11. ( ) The Basics ⊛ Write a test shell ⊛ Write the code to make it work ⊛ Verify that it works ⊛ Repeat
12. ( ) The Reality ⊛ Write the code ⊛ Write the test ⊛ Make sure it works ⊛ This is not TDD!
13. ( ) Assertions ⊛ assertEquals(expected,result) ⊛ assertNotSame(expected,result) ⊛ assertSame(expected,result) ⊛ assertFalse(someVariable or function result) ⊛ assertTrue(someVariable or function result) ⊛ assertXPath(String xpath, any data, [String text], [String message]) ⊛ assertIsTypeOf(component obj, String type) ⊛ assertIsXMLDoc(any xml) ⊛ assertIsArray(any obj1) ⊛ assertIsDefined(any obj1)
14. ( ) Example ⊛ You’ve written a function. Now test it.
15. ( ) How to Test ⊛ Test one thing per test ⊛ Write tests for every possible scenario ⊛ Test for success and failure
16. ( ) How to Test ⊛ Test in isolation ⊛ setup()/teardown() ⊛ Mocking dependencies ⊛ injectMethod ⊛ injectProperty
17. ( ) How to Test Databases ⊛ <cftransaction action=”rollback” />
18. ( ) Debugging ⊛ <cfdump>/<cfoutput> ⊛ request.debug( ) method in tests ⊛ “Open test case results in browser”
19. ( ) Great Tutorial on TDD with MXUnit http://www.adobe.com/devnet/coldfusion/ articles/testdriven_coldfusion_pt1.html
