Doing TDD without a Test Runner

What can be done in VBA/VB6 and other environments is the following:

  • Create a code module that will serve as your test fixture.
  • Write individual methods to do your tests in this code module.
  • Have a "master" method that calls all of the individual tests.
  • The individual tests give you feed back ala debug.print with test name and"PASS" or "FAIL" also return a boolean to the master method.
  • The master method can return FAIL if it picked up a false from any of the test methods that were called.

Now you can use the immediate/debug window to call your individual test methods or your master test method. I found this approach very helpful when working with a legacy Access 97 application.
