Istanbul default excludes not working

[jaydenseric]

According to the istanbul docs:

The default exclude list is defined in the test-exclude module.

The defaults contain test{,-*}.{js,cjs,mjs,ts} and **/*{.,-}test.{js,cjs,mjs,ts}, so I don't know why such files are being coverage checked in my projects:

The workaround is to add a .nycrc.json file to your project like this:

{
  "exclude": ["**/*.test.*"]
}

The docs on github show master, unfortunately right now this is different from the currently released version. The default excludes for the current version of nyc can be viewed at https://github.com/istanbuljs/istanbuljs/blob/test-exclude%405.2.3/packages/test-exclude/index.js#L176-L184 (test-exclude@5.2.3).

The additional default excludes will be provided as part of test-exclude@6.0.0 and nyc@15.0.0. No ETA on the full release of these new versions, progress can be followed at istanbuljs/nyc#1104.

As of tap 14.7.2, it'll also explicitly exclude any test files it runs. Should fix this issue for you.
