Getting "Warning: You should set `SILENT_OBSERVATORY`" on 2020.2 build

[dpbadiola]

Hello team, just upgrade my IntelliJ to 2020.2 and am now getting this error on my test packages

Warning: You should set `SILENT_OBSERVATORY` to true when debugging the VM as it will output the observatory URL by default.
This breaks the various reporter contracts.
To set the value define `DART_VM_OPTIONS=-DSILENT_OBSERVATORY=true`.

All test files are working prior to the upgrade.
Here are some details am running on

• IntelliJ IDEA 2020.2 (Ultimate Edition), Build #IU-202.6397.94, built on July 27, 2020
• Flutter (plugin) - 48.0.4
• Dart (plugin) - 202.6397.47

Adding more info after running flutter doctor on a new project

[!] IntelliJ IDEA Ultimate Edition: is partially installed; more components are available. (version 2020.2)

Thanks for the report! I assume this is when running a flutter test?

The same issue, cannot run test after update flutter plugin (IntelliJ - 48.0.4/Android Studio - 48.0.2)

This appears when running any test with the lasted plugin.

Please solve this problem since it heavily strands TDD...

@grouma - we're seeing this when we run flutter test from IDEs. I think we should figure out why we're seeing this and if we should remove the error message from package:test. I can append the full command line that we're starting flutter test up with.

[devoncarew]

It looks like it's just flutter test --machine --start-paused

@Peng-Qian - you might be seeing a separate issue. If so, can you file a separate issue? And, in that issue you might mention what test/target you're running. I see flutter test --machine --start-paused test as your command like - note the trailing test at the end.

Hi @devoncarew , thanks for the support

I think that the issue with @Peng-Qian and @dpbadiola are the same as my:

Android Studio 4.0.1 - Build #AI-193.6911.18.40.6626763, built on June 24, 2020
Windows 10 10.0
Flutter Intellij Plugin 48.0.2
Dart Intellij Plugin 193.7361

Basically, after configuring a test run configuration, the tests don't run. It keeps stocked.

I think that this issue is related with #4622

Thanks,

Marco

My problem is exactly what @marcoprado17 shows...
I was trying to upload the same process screenshots...

[dpbadiola]

I can live with the bug by running flutter test on the terminal hope we can get a fixed update soon.

That warning shouldn't be preventing the tests from running. Note the warning was added due to this issue: dart-lang/sdk#31308

I suspect that the issue is related to the start-paused behavior as called out above in #4732 (comment)

[helin24]

I've made a temporary fix for directory scope tests hanging; there's some more information in #4737.

I am not sure yet what action we want to take on the silent observatory warning.

I raised an issue in the Flutter repo about this:

flutter/flutter#63075

For VS Code, I haven't seen it preventing the tests from running (we also use --start-paused), but it is confusing. I've been unable to suppress it by following the instructions it prints so I figured it was something that would need handling inside flutter test.

After updating the plugins, everything works now. Thanks team.
