Visual Studio Test Explorer Icons

Question

I've searched around and can't seem to find any reference to the light icon with the green check.

This FAQ only shows the solid green with white check version.

The test output seems to be the same as the green icon with the white check - just passing tests. All of the tests in the groups have run successfully, so it isn't like a partial run or something.

Does anybody know the difference in the icons?

Answer 1

They indicate passing/failing tests which weren't included in the last run.
