title: Use GitLab CI to run tests locally?
body: <p>If a GitLab project is configured on GitLab CI, is there a way to run the build locally?</p>
  
  <p>I don't want to turn my laptop into a build "runner", I just want to take advantage of Docker and <code>.gitlab-ci.yml</code> to run tests locally (i.e. it's all pre-configured). Another advantage of that is that I'm sure that I'm using the same environment locally and on CI.</p>
  
  <p>Here is an example of <a href="https://github.com/jolicode/JoliCi">how to run Travis builds locally using Docker</a>, I'm looking for something similar with GitLab.</p>
