Test failure: ProcessStart_UseShellExecute_OnUnix_SuccessWhenProgramInstalled(isFolder: False)

[wtgodbe]

The test is failing on Linux with:

Assert.Equal() Failure
↓ (pos 0)
Expected: xdg-open
Actual: sh
↑ (pos 0)

There are a few related failures, such as ProcessStart_OpenFileOnLinux_UsesSpecifiedProgramUsingArgumentList(programToOpenWith: \"vi\"). These appear to have been introduced by dotnet/corefx@8b515ad#diff-c2151a182d9032ef4525c69b3569d024 & dotnet/corefx@4214b09#diff-c2151a182d9032ef4525c69b3569d024. The first change is in release/3.0, so we're seeing the failures in preview5 as well.

This should be fixed by dotnet/corefx#37144.

@danmosemsft that PR actually reintroduced these test failures. The timeline goes:

dotnet/corefx#36913 - caused the intial set of failures (this is the current state in release/3.0)
dotnet/corefx#37113 - reverted the previous change, fixed the test failures
dotnet/corefx#37144 - reintroduced the test failures

Oh... @tmds

[wtgodbe]

These are outerloop tests, which is why we missed them in CI. You can see the failures from this PR: dotnet/corefx#37197

I need to investigate further, but on first sight, these may be things we need to update in the tests:

• LongProcessNamesAreSupported is failing on Alpine. The test itself may be incompatible with Alpine. busybox figures out what the process should do based on the name, and the test is renaming to something busybox doesn't know.
• ProcessStart_UseShellExecute_OnUnix_SuccessWhenProgramInstalled is failing on a number of distros but not on all. It may have to do with the way xdg-open works.

[stephentoub]

I'm disabling this test temporarily, as it's causing all outerloop linux runs to fail.

[stephentoub]

I'm also disabling ProcessTests.LongProcessNamesAreSupported against this issue.

[stephentoub]

And ProcessTests.ProcessStart_OpenFileOnLinux_UsesSpecifiedProgramUsingArgumentList

@stephentoub we need some input here: dotnet/corefx#37294 (comment)
