Group the test with test categories

- [Voiceover] In MS test,…we've seen that you use the test class attribute…to indicate that a class contains one or more tests.…And you use the test method attribute…to indicate what methods contain the test.…There are additional attributes that…you can apply at the method level.…I'd like to look at the test category attribute.…This attribute enables you to group your tests…into meaningful categories.…This takes a single string argument,…that's the name of your category.…Since this is my constructor test,…I'll call this test category Constructor.…

And I'll copy this and paste it in here…because I have two constructor tests.…Then I'll compile my app.…Next, we'll look at what happens in the test explorer.…Currently, I'm grouping by class name.…So I see there are seven tests in my category example class.…I'm going to go up to this drop down,…there's another choice here.…There's one called Traits.…Test category is considered a trait.…So when I choose this, you'll see that it…reorganizes my tests and groups them by their trait names.…
