Unexpected error detected. Check the Tests Output Pane for details.
Where is the \'Tests Output Pane\'? I can\'t find it anywhere in Visual
In the output window there is combobox "show output from". Choose Tests as shown here
For me killing vstest.console.exe and vstest.discoveryengine.exe processes did the trick. No need to restart visual studio.
The message really should be this
Unexpected error detected. Check the
Output Window
for details which can be found in theShow output from:
section. Then select theTests
drop down to read the actual error.
For it is in the output window which is the same window which also primarily shows the textual Build
information ... and the test result info.
If you're looking for the actual issue, for me it was:
vstest.discoveryengine.exe and vstest.executionengine.exe
Open up Task Manager, go to Processes tab, right-click and End Process. Restart Visual Studio.
Go to the view tab at the top of your screen, and select output.
