title: Ignoring a specific flake8 rule for a folder
body: <p>I am using <code>flake8</code>, <code>flake8-docstrings</code> and many other <code>flake8</code> plugins in our project</p>
  
  <p>I want to disable <code>flake8-docstrings</code> only for our <code>test</code> folder.</p>
  
  <p>I want to avoid running flake8 twice because it would mean that running flake8 wouldn't be the straight forward <code>flake8 .</code> anymore. Not only that would mess with my ide settings, that would also be another excuse for the other developers in my project to not run <code>flake8</code>.</p>
  
  <p>Is there a way to configure flake8 to exclude specific rules just for a specific folder?</p>
