Standard output appended to test results disappears when selecting test run

[timheuer]

Type: Bug

After a test run, the Test Results window shows the standard output. When I select a test/test run, the output disappears and there is no way to make it re-appear.

This standard output is being appended to the test result model per the C# Dev Kit (@peterwald)

You can make it reappear by clicking the little "console" icon next to the test run. This isn't shown automatically since the test run is (or should be, fixed in #214271) expandable, so it would be confusing when interacting with the twistie.

[timheuer]

Wow, okay, that feels invisible. FWIW in VS these are together.

[connor4312]

Yea, it's the most obvious thing in the world, but is kind of how trees work. Note that you can also click the terminal icon on the test to view output correlated with the test, you highlighted in your screenshot from VS.

At some point we will add stacktrace support in test messages at which point we'll probably have some richer "test detail summary" with information similar to your screenshot in VS.

[timheuer]

I know I'm n=1, but I would have never discovered the 'only visible in hover state' console button. It's weird to me that output associated with the test isn't all in the same place. To me, as a user, I don't know what trees are, I just want to see ALL my output when I select the test. Please consider a change.

[timheuer]

@connor4312 Can you update documentation for Test area? I don't see anything in the TOC for user guide.

It would be good to have a Testing entry in the TOC here, explaining the test explorer, test results output, trees, this console thing, etc. Thank you!

[connor4312]

There is already a WIP on that here :) microsoft/vscode-docs#7310

This issue has been closed automatically because it needs more information and has not had recent activity. See also our issue reporting guidelines.

Happy Coding!

[connor4312]

@timheuer fyi the next release of VS Code will ship support for call stacks, by setting the TestMessage.stackTrace property.
