Trying to record typing into a date field doesn't work for me, it just types on the yyyy section of the date and ends up completely invalid.

What I've had work really well was replacing await page.type(selector, '2020-08-07'); with:

await page.focus(selector);
await page.keyboard.type('20200807');

Would it be within scope of the extension to recognize date inputs

After the introduction of Public workers API, run-workers can be refracted with the help of this API. This will help us to make enhancements and fixes on workers seamlessly.

The current mock mechanism is "strict" regarding trailing slashes:

mockiavelli.mockGET('/example', {status: 200})
// GET /example/ => 404

This behaviour should be at least configurable to allow ignoring trailing slashes:

const mockiavelli = await Mockiavelli.setup(page, {ignoreTrailingSlashes: true});
mockiavelli.mockGET('/example', {status: 200})
// GET /example/ => 200
