Ubuntu Linux: Exception calling "AddTestResult" with "8" argument(s)

[nvarscar]

T## 1. General summary of the issue
It block throws an error after successful completion on Linux Ubuntu environment in Appveyor:

Exception calling "AddTestResult" with "8" argument(s): "The attribute cannot be added because variable Result with value  would no longer be valid."

It runs perfectly fine on Windows.

2. Describe Your Environment

Operating System, Pester version, and PowerShell version:
Ubuntu 18.04 LTS
PowerShell Core 6.1.1

The error occurs during Appveyor CI build, that's the best I can get.

Erroneous build:
https://ci.appveyor.com/project/nvarscar/dbops/build/job/qavfvq159x6tmt1e
Errors exported via Export-CliXml

Trying to run tests in both Windows and Linux to confirm full Xplat compatibility.

Thanks for reporting this seems to affect only Ubuntu on AppVeyor, all my builds in docker and on Travis run just fine. We are already trying to figure out the error in #1101

[nvarscar]

Okay, got it. I'm digging through the logs now, there are actually proper test results in the $error array after all. Tests are indeed failing, but the error thrown is not the one that is expected.
Thanks for looking into it.

This is due to bug PowerShell 6.1 that makes Hashtables case sensitive on Linux, see #1101, and fixed by PR and released as 4.4.4 .

Thanks a ton for a quick fix Jakub!
