Summary

The first nightly run after cat-github-actions#188 merged (setting SIMPLECOV=yes on the Codecov lane) hung on "Run tests" for 20+ minutes instead of the usual ~10 seconds: https://github.com/puppetlabs/provision/actions/runs/38230880363/job/114749911485 (cancelled).

puppetlabs_spec_helper's module_spec_helper.rb does this whenever SIMPLECOV=yes:

begin
  require 'codecov'
  SimpleCov.formatters << SimpleCov::Formatter::Codecov
rescue LoadError
  # continue without codecov
end

This repo's Gemfile has gem "codecov", require: false (leftover from an old Travis/.sync.yml simplecov: true setup), so the require succeeds and that formatter gets registered. Its format method makes a real synchronous Net::HTTP call straight to https://codecov.io/upload/v4 (falling back to /upload/v2), with retries on timeout/socket errors, and explicitly disables WebMock first so the call isn't stubbed. That legacy direct-upload API was replaced years ago by the codecov CLI that codecov-action@v4 already uses — hitting it now appears to hang rather than fail fast, which is what stalled the job.

Removing the gem makes that require raise LoadError, which is caught and ignored — SimpleCov just skips that formatter. The HTML + Console formatters still write coverage/.resultset.json, which is all codecov-action needs.

Test plan

• Re-run nightly and confirm "Run tests" completes in roughly the same time as before SIMPLECOV was introduced, with the Codecov upload step still succeeding.
