Writing a batch of unit test for testing a range of values can get tedious. This video looks at the concept of unit test parameters and how they can simplify testing ranges of values in a unit test. It also explains why the MsTest framework is not the best framework for working the test parameters.
- [Voiceover] Here's another situation…that appears when writing unit tests…that need to test a wide range of values.…In some cases you'll find yourself…creating dozens of tests to exercise…the code with the values.…I'll show you an example in this…NumberAnalyzer class.…On line 10, I have a constructor…that takes a CandidateNumber.…On line 13, I have a method…that returns a bool that's called…ContainsOddDigit.…The idea is, we'll look at the CandidateNumber.…If any of the digits are odd,…I'll return true.…
So if I pass the number 100, I'll get true.…If I pass the number 24, I'll get false.…To test this, I created a separate class,…CheckingForOddDigit_Should.…I compiled the project so…I could see my unit test.…I have seven tests.…As you noticed, the more tests you get,…the harder it is to find the test in here.…I do have good names for my tests…but it's getting harder to find them.…One thing you can do is go to your Test Explorer…and choose to group by the class name.…Now I see all the unit tests that are in.…
