Using this test class as an example:
public class HighlightReSharperIssue
[TestCase(2, Result = 4)]
[TestCase(3, Result = 9)]
public int Square(int a)
When you "Run All", every test case is run. When you attempt to run an individual case, the test is ignored so long as the Explicit attribute exists on the class.
Here's the version I'm using:
