No test assemblies found matching the pattern: **\*Test*.dll,!**\*TestAdapter.dll,!**\obj\**

Question

I am trying to implement a Gated Check-In process in Azure DevOps (VSTS) based on the success of the unit tests. However, I am consistently getting this warning/error that assemblies are not found.

##[warning]No test assemblies found matching the pattern: **\*Test*.dll,!**\*TestAdapter.dll,!**\obj\**.
##[debug]Processed: ##vso[task.issue type=warning;]No test assemblies found matching the pattern: **\*Test*.dll,!**\*TestAdapter.dll,!**\obj\**.
======================================================

All my unit tests run successfully in Visual Studio 2017 in Test Explorer locally.

The Azure DevOps documentation seems straightforward but it does not work when I follow it.

I am using a Hosted VS2017 Agent. The CI Build itself succeeds upon check in to TFS source control.

The "old" .NET had the files located in the Release folder (which is described by the BuildConfiguration variable).

.NET Core builds contain an extra folder:

YourNamespaceHere.UnitTests > bin > Release > netcoreapp2.1 > dll's

When you add an extra wildcard, the build will find the unittest dll's.

**\$(BuildConfiguration)\*\*unittests.dll

I have renamed the *Tests* part to *unittests.dll as my project also contains integrationtests.
