Update simplecov requirement from < 0.18 to < 0.21

[dependabot-preview]

Updates the requirements on simplecov to permit the latest version.

Release notes

Sourced from simplecov's releases.

v0.20.0

The "JSON formatter" release. Starting now a JSON formatter is included by default in the release. This is mostly done for Code Climate reasons, you can find more details in this issue. Shipping with so much by default is sub-optimal, we know. It's the long term plan to also provide simplecov-core without the HTML or JSON formatters for those who don't need them/for other formatters to rely on.

Enhancements

• simplecov_json_formatter included by default (docs), this should enable the Code Climate test reporter to work again once it's updated
• invalidate internal cache after switching SimpleCov.root, should help with some bugs

0.19.1 (2020-10-25)

Bugfixes

• No more warnings triggered by enable_for_subprocesses. Thanks to @mame
• Avoid trying to patch Process.fork when it isn't available. Thanks to @MSP-Greg

0.19.0 (2020-08-16)

Breaking Changes

• Dropped support for Ruby 2.4, it reached EOL

Enhancements

• observe forked processes (enable with SimpleCov.enable_for_subprocesses). See #881, thanks to @robotdana
• SimpleCov distinguishes better that it stopped processing because of a previous error vs. SimpleCov is the originator of said error due to coverage requirements.

Bugfixes

• Changing the SimpleCov.root combined with the root filtering didn't work. Now they do! Thanks to @deivid-rodriguez and see #894
• in parallel test execution it could happen that the last coverage result was written to disk when it didn't complete yet, changed to only write it once it's the final result
• if you run parallel tests only the final process will report violations of the configured test coverage, not all previous processes
• changed the parallel_tests merging mechanisms to do the waiting always in the last process, should reduce race conditions

Noteworthy

• The repo has moved to https://github.com/simplecov-ruby/simplecov - everything stays the same, redirects should work but you might wanna update anyhow
• The primary development branch is now main, not master anymore. If you get simplecov directly from github change your reference. For a while master will still be occasionally updated but that's no long term solion.

0.18.5 (2020-02-25)

Can you guess? Another bugfix release!

Bugfixes

• minitest won't crash if SimpleCov isn't loaded - aka don't execute SimpleCov code in the minitest plugin if SimpleCov isn't loaded. Thanks to @edariedl for the report of the peculiar problem in #877.

0.18.4 (2020-02-24)

Another small bugfix release 🙈 Fixes SimpleCov running with rspec-rails, which was broken due to our fixed minitest integration.
