v0.21.2

Bugfixes

• maximum_coverage_drop won't fail any more if .last_run.json is still in the old format. Thanks @petertellgren
• maximum_coverage_drop won't fail if an expectation is specified for a previous unrecorded criterion, it will just pass (there's nothing, so nothing to drop)
• fixed bug in maximum_coverage_drop calculation that could falsely report it had dropped for minimal differences

v0.21.1

Bugfixes

• minimum_coverage_by_file works again as expected (errored out before 😱)

v0.21.0

The "Collate++" release making it more viable for big CI setups by limiting memory consumption. Also includes some nice new additions for branch coverage settings.

Enhancements

• Performance of SimpleCov.collate improved - it should both run faster and consume much less memory esp. when run with many files (memory consumption should not increase with number of files any more)
• Can now define the minimum_coverage_by_file, maximum_coverage_drop and refuse_coverage_drop by branch as well as line coverage. Thanks to @jemmaissroff
• Can set primary coverage to something other than line by setting primary_coverage :branch in SimpleCov Configuration. Thanks to @jemmaissroff

Misc

• reduce gem size by splitting Changelog into Changelog.md and a pre 0.18 Changelog.old.md, the latter of which is not included in the gem
• The interface of ResultMeger.merge_and_store is changed to support the collate performance improvements mentioned above. It's not considered an official API, hence this is not in the breaking section. For people using it to merge results from different machines, it's recommended to migrate to collate.

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

v0.19.1

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

v0.19.0

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.

v0.18.5

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.

v0.18.4

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

Bugfixes

• SimpleCov will run again correctly when used with rspec-rails. The excellent bug report #873 by @odlp perfectly details what went wrong. Thanks to @adam12 for the fix #874.

v0.18.3

Small bugfix release. It's especially recommended to upgrade simplecov-html as well because of bugs in the 0.12.0 release.

Bugfixes

• Fix a regression related to file encodings as special characters were missing. Furthermore we now respect the magic # encoding: ... comment and read files in the right encoding. Thanks (@Tietew) - see #866
• Use Minitest.after_run hook to trigger post-run hooks if Minitest is present. See #756 and #855 thanks (@adam12)

v0.18.2

Small release just to allow you to use the new simplecov-html.

Enhancements

• Relax simplecov-html requirement so that you're able to use 0.12.0
