Navigation to test output from Test Explorer #4279

Clicking on a test function in the code explorer should open the Output pane to show the output that test emitted. Open the Output :: Python Test window only, not navigate to the specific output for a specific test.

User clicks with right-mouse click and then chooses 'Show Unit Test Output' to get this functionality.
