Unit Testing for Hash Code

Unit testing is a key for C# code since it can help in maintaining code in the development process. It lets you know about the problems in the development cycle.

With Unit Testing, you can make the code reliable and reusable.

One of the fundamental principles of adopting unit testing is to follow a TDD (Test Driven Development) approach where we have to write tests case first, and then write the simple code that will make the test pass

For Unit testing, you need to work with Microsoft Testing tools, which is what we call MS Unit Test.

Now select "Unit Test Project" −

Set a name for the Test and click Ok.
