[Error Handling] Test section improvements

[xoscar]

This ticket is part of the epic #2040 to improve the UX/UI when running a test

AC1
As a user looking at the test mode
And some of the test specs failed to process/execute
I should be able to see error marks around them with the description of what happened

AC2
As a user looking at the test mode
And some of the outputs failed to be created
I should be able to see error marks around them with the description of what happened

AC3
As a user looking at the test mode
And there are some failed test specs
I should see a more prominent error status

• Add possible error and warning messages for outputs/test specs
