	// Enabling synchronous mode (via the wdio-sync package), means specs don't have to
	// use Promise#then() or await for browser commands, such as like `brower.element()`.
	// Instead, it will automatically pause JavaScript execution until th command finishes.
	//
	// For non-browser commands (such as MWBot and other promises), this means you
	// have to use `browser.call()` to make sure WDIO waits for it before the next
	// browser command.

	deprecationWarnings: true,

	// Stop the tests once a certain number of failed tests have been recorded.
