Now if you run the code coverage tool again, you should get 100% covered blocks for all your code you have written. In this case of test method the if statement of actual code block will execute. To cover that part of code using your unit test, you can just add another test method that pass two negative values. As per our actual logic, which is nothing but testing the code with both negative parameters. Now, from this color highlighting you can see what part is missing from your unit test case.

Code Coverage let us determine which portion / section of the code has been tested. Understanding and maintaining the code coverage is one of the most important aspect of writing unit tests and ensures the code quality with respect to functional points.
