This tutorial shows how to add an Assert class to the test project. The logic for asserting that the code works as expected in refactored from the individual test methods into the new Assert class.
- [Voiceover] Most unit-testing frameworks…have a helper class that handles the assertions,…and it's usually named, Assert.…I'll create an Assert class and put it in TestingLib.…I'll mark it as a public static class,…and then we'll talk about where I created this class.…I created in in TestingLib, is that the best place…for me to put this Assert class?…Probably not.…It really should go in a separate unit-test project.…That way I can reuse it across other applications.…So the way I see it, BrokerageLib is my system under test.…
TestingLib contains all of the tests…that I use to test the BrokerageLib.…Assert belongs in a fourth project…that contains all of my helper methods,…and I would use that across multiple projects.…But for simplicity's sake,…I'll keep the Assert class in TestingLib.…Typically in an Assert class, you have multiple methods…that you call to verify that your code meets your criteria.…That is, meets your expectations.…I've seen methods in a certain class called IsTrue.…
You would call this to verify that a boolean variable…
