  <h1 class="post-title">Passing Specs per Ruby Implementation</h1>
  <p>
    This page shows the number of passing <a href="https://github.com/ruby/spec">ruby/spec</a> specs per Ruby implementation.
    This page is updated daily and automatically with GitHub Actions on <a href="https://github.com/eregon/rubyspec-stats">this repository</a>.
  </p>
  <p>
    Specs excluded by a Ruby implementation (via tags) are not run, as those may cause a fatal error and abort the process, and also they are not run in that implementation's CI.
    Specs are run on a Ruby implementation with no extra options, i.e., with the default behavior a user would see.
    The only exception is using <code>--dev</code> on JRuby so it runs specs slightly faster.
    More details are available in this related <a href="https://eregon.me/blog/2020/06/27/ruby-spec-compatibility-report.html">blog post</a>.
  </p>
  <p>
    More Ruby implementations are welcome via PRs.
    See <a href="https://github.com/eregon/rubyspec-stats/blob/master/.github/workflows/ci.yml">this workflow</a> for how it works.
