PR Summary

On Linux and macOS, PowerShell expands wildcards in unquoted arguments of native commands, matching file names in the current directory without regard to case. The test verify `dsc resource list * adapter_filter` in dsc/tests/config/dsc_args.tests.ps1 runs

dsc resource list '*' -a Test* -o json

When the tests run from the repository root, Test* matches the tests folder, so dsc gets -a tests and fails:

error: invalid value 'tests' for '--adapter <ADAPTER_NAME>': invalid literal type name filter: invalid fully qualified type name 'tests': missing required name segment following forward slash (`/`) character

The test still passes. It only checks the resources that come back, and none do.

This PR:

• quotes the wildcard filters in dsc_args.tests.ps1, as the test above it already does with '*'
• checks the exit code in the adapter filter test, and that it finds at least one resource. With the quoted filter, it finds the four resources of Test/Adapter and Test/TestGroup.

The test on line 169 only runs on Windows, where PowerShell doesn't expand the arguments. I quoted it as well so that the file is consistent.

PR Context

With the filter unquoted, the new checks fail on Linux (Expected 0, but got 2). With it quoted, both adapter filter tests pass.

What changed in this PR

This PR makes DSC argument tests more reliable by preventing PowerShell wildcard expansion on Linux and macOS and detecting adapter-listing failures.

Changes:

• Quotes wildcard resource and adapter filters, including the Windows-only tracing test.
• Adds exit-code and nonempty-result assertions so the adapter filter test cannot pass without returning resources.
