title: How can I locate resources for testing with Cargo?
body: <p>I'm on a project interacting with files, and I would like to use text files to test my work. However tests aren't run from the <code>tests/</code> directory, and thus I cannot reliably find them when running <code>cargo run</code>.  </p>
  
  <p>Does Cargo handle this by always running test from the root directory (which seems to be the case but I didn't find anything attesting it)?</p>
