title: How to initialize the logger for integration tests?
body: <p>I have a crate with production code in the <code>src</code> directory and integration tests in the <code>tests</code> directory. The production code uses <code>log</code> macros.</p>
  
  <p>I would like to init a global logger when running the integration tests (e.g. <code>env_logger::init().unwrap();</code>)
  There are several tests and the test order is not defined, so I don't know in which test I should put the initialize command.</p>
  
  <p>Is there any way I can do this nicely? Perhaps by overriding the tests <code>main</code> function?</p>
