Extensions are no longer loading as is currently documented

[mmalandra-kb4]

NUnit Engine/API versions 3.19.1.

How should extensions be loaded now? With the latest nunit-console (3.19.1) and engines/api, our extensions are no longer loading.

From the source code, you can see a major change here where the code is only looking at specific folders that match hardcoded patterns:

public void FindExtensionAssemblies(Assembly hostAssembly)
{
    log.Info($"FindExtensionAssemblies called for host {hostAssembly.FullName}");

    bool isChocolateyPackage = System.IO.File.Exists(Path.Combine(hostAssembly.Location, "VERIFICATION.txt"));
    string[] extensionPatterns = isChocolateyPackage
        ? new[] { "nunit-extension-*/**/tools/", "nunit-extension-*/**/tools/*/" }
        : new[] { "NUnit.Extension.*/**/tools/", "NUnit.Extension.*/**/tools/*/" };


    IDirectory startDir = _fileSystem.GetDirectory(AssemblyHelper.GetDirectoryName(hostAssembly));

    while (startDir != null)
    {
        foreach (var pattern in extensionPatterns)
            foreach (var dir in _directoryFinder.GetDirectories(startDir, pattern))
                ProcessDirectory(dir, true);

        startDir = startDir.Parent;
    }
}

Does the documentation around loading extensions need to be updated, or is there a way to get engine to allow for other folders to contain extensions?

Is Chocolatey involved in your case? Then have a look at #1614

Addins files must still be supported #1504

We are not using chocolately.
