Test a login flow without writing Playwright: test account, cookie banner, captcha
Login is the door to everything else. When it breaks, your uptime stays green. Here is how to monitor sign-in in a real Chrome without writing a script.
Why login breaks without uptime noticing
The /login page returns 200 even when the button no longer does anything. A third-party script that fails to load, an identity provider that changes its redirect, a field renamed after a release: the page renders, sign-in fails.
The only test that proves it is a visitor’s: open the page, type an email and a password, click, then check you really land in the signed-in area.
Record the journey instead of coding it
In Pathly, you open your site in the recorder and sign in as usual. Each click and each keystroke becomes a step. Finish with a text check on something only visible once signed in, such as the account name or “Log out”.
- Open the sign-in page and wait for the form.
- Fill in the test account’s email and password.
- Click “Sign in”, then check a text from the signed-in area.
If a selector changes later, you fix it in the step list without recording again. When it fails, the run keeps a screenshot of the failing step.
A dedicated test account, never a real one
The typed password is part of the scenario. So create an account reserved for monitoring, with no admin rights, no customer data, and a password used nowhere else. If that account leaks, it opens nothing that matters.
Cookie banner, captcha and two-factor authentication
The cookie banner is handled with a conditional step: if the “Accept” button is visible, click it, otherwise move on. The journey no longer breaks on days the banner does not show.
A captcha or a one-time code exist to stop robots, and Pathly is one. Do not try to beat them: exempt the test account on your side, or recognise monitoring traffic with an HTTP header you define and Pathly adds to every request.
What if login goes through an API?
For an app whose front end calls an auth API, Chain tests the same thing without opening Chrome: a first call gets the token, the next one uses it on a protected route. It is faster and cheaper, but it does not see a broken button. The two complement each other.
