Is there an existing issue for this?

• I have searched the existing issues.

Version

Description

Some tests are flaky when they run for Linux in the the CI, example run:
https://github.com/invertase/melos/actions/runs/8373797082/job/22927655150

Steps to reproduce

Run the CI and ~50% of the time some linux tests will fail.

Expected behavior

Non-flaky tests.

Apparently also sometimes happens for windows:

Here's another one: https://github.com/invertase/melos/actions/runs/8420212367/job/23054448154

@jessicatarra maybe you could have a look at this test if you have time: "multiple scripts verifies that a melos script can call another script containing steps, and ensures all commands in those steps are executed successfully"? :)
It seems to be the one that is the most flaky.

[jessicatarra]

Sure, I'll take a look

https://github.com/invertase/melos/actions/runs/8434508600/job/23098706712?pr=679 this seems to be the same problem as the one you solved right @jessicatarra, but on another test?

[jessicatarra]

I'm uncertain if this is a flaky test, it seems like a real issue because it's failing across all environments, possibly a missing dependency. I'll take a look at this too

@spydon it's actually a flaky one so disregard my previous comment, it's actually a very similar issue as you mentioned, see the most recent log:

 test/workspace_test.dart: Workspace can be accessed from anywhere within a workspace (failed)
  Expected: 'a\n'
              ''
    Actual: 'Resolving dependencies...\n'
              'Got dependencies!\n'
              'a\n'
              ''
     Which: is different.
            Expected: a\n
              Actual: Resolving  ...
