how to handle AR model classes with no methods

[danmayer]

They have no methods, as a pure pass through to the DB... so they have 100% coverage based on being loaded... how can we tell if they are in use or not?

Example from @kbaum

I think we need a strategy for finding unused classes that get 100% coverage because of eager loading.

[danmayer]

The best idea I have for this is looking for callers via grep or static analysis... which gets a bit outside of Coverband's primary expertise.

[danmayer]

Still probably beyond what we want to do in Coverband, but we could subscript to this notification event.

Then we could record last time instantiated, similar to how the view tracker works and records when views are used.

We now display things differently for files that have no runtime coverage and wouldn't expect to... It think this is good to close out
