How to create a unit test and start debugging in VS2015, and create a unit test in vs2015

1: Add Unit Test

2: Open unit test class

Key points:

Class: [TestClass], method: [TestMethod], method output: Assert. IsNotNull (s, "test failed ");

Here, Assert. IsNotNull () is the method for determining whether the unit test is successful. There are other methods. s is the judgment object, and "test failed" is the output content if the unit test fails.

During debugging, there is a small icon on the unit test method, and you can click to choose run or debug. (if there is no small icon, You need to compile the entire solution to pass)
