Hi @lonitra, It seems that a unit test failed, but I couldn't find which specific unit test case it was from the concise log. Would you please let me know how to get more detailed unit test logs or locate the failed unit test case? Thanks.

I noticed that we dont have any tests for this either. It might be good to add some basic unit tests for getting the renderer in ToolStripItemTests

A unit test of ToolStripItemRenderer_GetReturnsExpected added.
