Description

I see #604 was already filed, but it's a few years old and the suggested option to try (nyc-arg) gets rejected by tap.

My situation: I work on a project that has some codegen as part of its build step (protobuf JavaScript interface) and I don't want that file to be tracked as part of code coverage. I tried using exclude but that didn't work.

Example

{
  "exclude-coverage": ["src/pubsub/events.pb.js"]
}

Perhaps something that exactly follows the same rules for exclude for excluding files from being run as part of test execution, but instead applies to tracking code coverage.
