title: Executing multiple tests paths using craftcms and codeception
body: <p>For a Craft CMS/Yii2 project using Codeception I'd like to execute testing on multiple plugins, meaning from multiple sources within the <em>vendor</em> directory.</p>
  <p><a href="https://codeception.com/docs/reference/Configuration" rel="nofollow noreferrer">https://codeception.com/docs/reference/Configuration</a></p>
  <p>Sadly the above documentation only seems to mention a single option for the 'tests' file path. Would it be possible and advisable to somehow implement this, for example by using symbolic links?</p>
  <p>Current situation:</p>
  <pre><code>paths:
      tests: tests,
      output: tests/_output
      data: tests/_data
      support: tests/_support
      envs: tests/_envs
  </code></pre>
  <p>Example of desired situation:</p>
  <pre><code>paths:
      tests: vendor/foo/bar/tests, vendor/foofoo/barbar/tests
      [...]
  </code></pre>
