title: How to make Cargo run tests for local dependencies?
body: <p>I'm working on a project split across multiple crates. The top-level crate (the app) requires the two other crates (libraries) as dependencies. Running <code>cargo test</code> in the top-level crate builds the dependencies and runs tests for the top-level crate, but it doesn't run tests for the two other crates. Is there a way to configure <code>cargo test</code> so that it will run tests in all three crates?</p>
  
  <p>Thanks!</p>
