test: Native Render

[paulhazen]

The following PR adds unit tests that confirm the equivalency of config values as read from the native and managed components of the plugin.

[!IMPORTANT]
This PR has been moved to draft pending an internal discussion regarding the best testing framework to utilize.

Note

Discussion was had internally, and it was agreed that having tests in some framework was preferable to having no tests - and that changing testing frameworks would be something trivial to do at a later date if it was deemed necessary.

Not so comfortable that the solution requires the test to compile.

The solution only requires the tests to compile if in Debug mode - otherwise the Test project is not required.

I feel like a test like this is better in a separate solution.

It's standard practice to put test projects in the same solution as the projects that they are designed to test.

Also there is an extra .net 4.8 dependency introduced somewhere that I'm not quite sure why.

That dependency is only for ManagedPluginCode, which is an existing dependency not introduced by this PR.

I believe we need to discuss testing frameworks.

I believe we need to discuss testing frameworks.

We've now had the discussion internally - and I believe that the consensus was to include these tests as it would be easy to change unit testing frameworks later, and would be good to have tests in some framework rather than no tests at all.
