t.debug Method

Pauses the test and allows you to use the browser’s developer tools. Chainable.

t.debug() → this | Promise<any>

When test execution reaches t.debug, it pauses so that you can open the browser’s developer tools and check the web page state, DOM element location, their CSS styles, etc.

You can also use the --debug-mode command line option to pause the test before the first action or assertion.
