It uses the Assert.AreEqual method to verify that the ending balance is as expected.

The method throws an ArgumentOutOfRangeException if the debit amount is less than zero. The method throws an ArgumentOutOfRangeException if the debit amount is greater than the balance. There are at least three behaviors that need to be checked: In this procedure, you'll write unit test methods to verify the behavior of the Debit method of the BankAccount class. You can call these other classes and methods from your test methods. You can have other classes in a unit test project that do not have the attribute, and you can have other methods in test classes that do not have the attribute. The attribute is required on any class that contains unit test methods that you want to run in Test Explorer.Įach test method that you want Test Explorer to recognize must have the attribute. The minimum requirements for a test class are: At the top of the class file, add: using BankAccountNS The BankAccountTests.cs file now contains the following code: using Īdd a using statement to the test class to be able to call into the project under test without using fully qualified names.
