How do I write a unit test in PDK?
PDK runs your unit tests to ensure that your code works as you expect it to, but it cannot test changes to the managed system or services. When you generate a class, PDK creates a unit test file. This test file, located in your module’s /spec/classes folder, includes a basic template for writing your unit tests.
