Description

If you use a class for the TestCase the Visual Runner will just collapse those into a single test.

Tests using primitives for data all get split into different test cases

If you check the TheoryDiscoverer you'll see that it only generates the one test case. We'll need to look into the xUnit source code to see what logic it uses to split up test cases and why it doesn't do it for class based TestData.

Currently in our test runner if you have a test case that falls into this category we will just display the last failed result otherwise you only see the result of the last test executed. If the last test is green then it hides the failures from the UI.
