title: Change current working directory in Azure Pipelines
body: <p>I'm developing a CI for Python package in Azure Pipelines (<a href="https://github.com/scikit-image/scikit-image/blob/azure-pipelines/azure-pipelines.yml" rel="noreferrer">https://github.com/scikit-image/scikit-image/blob/azure-pipelines/azure-pipelines.yml</a>). At some point, I need to step out of the source code directory to allow <code>pytest</code> to discover an installation of this package, and run the corresponding tests.</p>
  
  <p>The issue I'm facing is related to the fact that <code>cd</code>, <code>cd C:</code>, etc commands do not seem to cause any effect, so that the current working directory remains unchanged (in this specific case, <code>D:\a\1\s</code>).</p>
  
  <p>Is there a way to overcome the described limitation?</p>
