* `:screenshot_dir` - The directory to store screenshots.
* `:screenshot_on_failure` - if Wallaby should take screenshots on test failures (defaults to `false`).
* `:max_wait_time` - The amount of time that Wallaby should wait to find an element on the page. (defaults to `3_000`)
* `:js_errors` - if Wallaby should re-throw javascript errors in elixir (defaults to true).
* `:js_logger` - IO device where javascript console logs are written to. Defaults to :stdio. This option can also be set to a file or any other io device. You can disable javascript console logging by setting this to `nil`.
