https://github.com/avajs/ava/blob/master/docs/recipes/debugging-with-vscode.md recommends passing the `debug` option to Ava.  However, in my experience Ava waits indefinitely when this option is used, without actually running any tests.

The increased timeout setting is so that tests won't fail prematurely because you're slowly stepping through code.
