Now that the projects are setup, it time to write the first unit test in the TestingLib. This tutorial details the steps necessary to make the test method. There is also a section devoted to creating a UnitTestInfo structure, which is used to transfer the information back to the Test Runner app.
- [Voiceover] I'll put my test code in testing library.…The first step is to verify that I have a reference to…Brokerage lib.…I do.…Next I'll delete the default class and add my own.…I'll be calling this class from my test runner…so I should make it public.…And then every scenario that I test I'll have a method…inside this test class.…I need to make those public too because I'll be…calling those from the test runner.…
I've called my class TestThePaymentDate and the name…of my method is DateIs30DaysInFuture.…We can do a better job at naming these,…but I'll talk about that later in the course.…The reason why I picked 30 is our business rule…is that we want a payment date that is at least…30 days in the future.…It can't be less than that.…Now I'm ready to write my test code.…The first thing I need to do is instantiate the…payment date class.…Before I write this code.…Delete that.…
I should add a using statement up here.…I usually do this.…This is the alias for brokerage lib.…I usually do this because it helps me differentiate…
