Run test suites in azure ci

[jneira]

• This is the more promising option for running tests in macos and windows (thanks god and @alanz at least we have the circle ci for linux)

• [X] Linux jobs: all test suites are green

• [ ] Windows jobs

  • [ ] unit-test suite:
    • Failing tests for CabalHelper using stack-8.6.4.yaml: openend https://github.com/DanielG/cabal-helper/issues/91
  • [ ] dispatcher-test: flaky, it fails sometimes for all ghcs always with same errors (see below)
  • [X] plugin-dispatcher: green
  • [ ] wrapper-test: failing
  • [ ] functional-test: one failing test for ghc-8.6.4 (Hover.hover works)

• [ ] macos jobs

  • [X] ghc-8.6.*: all test suites green
  • ghc-8.4.*:
  • [ ] test hangs after error in dispatcher test (see below)
  • [ ] functional test cant be run (func-test: fd:28: hPutBuf: resource vanished (Broken pipe))

Some of these issues should be fixed by #1126, so maybe we can try again to enable azure-ci testing, once that pr has landed.

I am just running the pr in azure with tests enabled: https://dev.azure.com/jneira/haskell-ide-engine/_build/results?buildId=212

Hi, after applying the workaround to avoid the errors compiling cabal-helper at runtime the number of failed tests has decreased sensibly:

• master: https://dev.azure.com/jneira/haskell-ide-engine/_build/results?buildId=219
  • Quite builds have only errors related with liquid haskell and even a linux build succeded: https://dev.azure.com/jneira/haskell-ide-engine/_build/results?buildId=219&jobId=86dfe75d-acf3-5a7d-391c-10fa0ecb27bb

The functional tests suite with the hie-bios branch hasmore fails: https://dev.azure.com/jneira/haskell-ide-engine/_build/results?buildId=221. Most of them are like:

haskell-ide-engine>   1) Completion.completions works
haskell-ide-engine>        uncaught exception: ConduitParserException
haskell-ide-engine>        NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "Logging notification" (BothFailed (Unexpected "ConduitParser.empty") (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "Logging notification" (BothFailed (Unexpected "ConduitParser.empty") (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "NotificationMessage ServerMethod PublishDiagnosticsParams" (NamedParserException "Logging notification" (BothFailed (Unexpected "ConduitParser.empty") (Unexpected "ConduitParser.empty")))))))))))))))

I've reran tests in azure with actual master: https://dev.azure.com/jneira/haskell-ide-engine/_build/results?buildId=334&view=results

• The unit-test suite passes
• The dispatcher and plugin-dispatcher suites pass
• The functional-test fails due to different behaviour of received diagnostics (logs: https://gist.github.com/jneira/ae1968cc67b28d3f222ed3001cbbc052)
• The wrapper-test fails due to different output of the stack command

[fendor]

This would be great! maybe we should start poking members of the haskell organizations to enable azure for this project?

[jneira]

Absolutely, do we know who has the permissions to do it, @alanz, @bubba?

[alanz]

I think the haskell committee has control of this. Not sure who specifically.

[jneira]

Ok, maybe we can wait to have the azure setup complete, including green test suites and deploy.

EDIT: i get linux and macos to run the entire test suite succesfully: https://dev.azure.com/jneira/0fa2df97-1d6d-4a00-935a-03a77e7170b8/_build/results?buildId=344&view=logs&j=d2c7b64e-54d7-53d5-7f80-77915c458472

Commenting the previous test triggers another functional errors, so i've deactivated func-test for win+cabal+ghc-8.4.4
