In an ideal situation, the code supporting application tests is written prior to, or at least at the same time as, when the code implementing the target application function is written.

Advantages of test-driven development include the following:

  • Designing testing processes in conjunction with functional design
  • Finding bugs early
  • Preventing bugs reaching production
  • Enabling regression testing, which prevents changes from introducing new bugs into previously validated routines

The AL Testability feature provides test-specific types of codeunits: test codeunits and test running codeunits. Test codeunits contain test methods, UI handlers, and AL code to support Test methods, including...
