title: Breakpoints don't work in VS2019 when running Pytest tests in debug mode
body: <p>When running tests in debug mode, writes &quot;The breakpoint will not currently be hit. No symbols loaded for this document.&quot; at breakpoints. At the same time, everything was fine even yesterday, i.e. all breakpoints worked. This error usually occurs if you start debugging without saving the changes to the project, but I saved all changes and restart VS2019. Tried many solutions from the net but nothing helps. Example:</p>
  <ul>
  <li>Enable and disable &quot;Just my code&quot; in settings debbuging;</li>
  <li>Remove all cache folder in project;</li>
  </ul>
  <p>Perhaps someone had similar problems?</p>
