Test Blazor topic

[guardrex]

From @guardrex at Test and debug Blazor apps topic ...

• Blazor development-time testing (as of 0.2.0, live reloading is still in design)
• Blazor unit testing

A debug topic exists. Because testing isn't the same thing as debugging, the test aspects probably go into a new topic. The dev-time testing/live reloading perhaps go into the existing debugging topic.

It's going to be a bit before we have our testing story for Razor Components worked out.

I think this is on hold for dotnet/aspnetcore#5458 and on the roadmap backlog (without an issue) on dotnet/aspnetcore#8177.

I'm going to move this to our HOLD column on the Blazor project for the time being.

@guardrex Instead of building our own Blazor unit test framework, we've decided to point folks to community based frameworks instead, like bUnit.

@egil do you want to propose an outline of of what this topic should look like?
