End-to-end testing and synthetic monitoring of interactive apps and sites is challenging. It's especially tough when non-deterministic flows such as cookie banners or promotion popups interrupt your test automation. This video teaches how to write Playwright tests that handle optional and surprising UI interactions. Note: Stefan decreased the default action timeout in this video to avoid spending time waiting for `click()` to timeout.

Learn in this video how you can monitor complex API endpoints using Checkly's gloabl API monitoring. Checkly's API checks are highly customizable with setup and teardown scripts. Pre-fetch auth tokens, sign requests, or create custom response assertions. It's up to you!

Learn in this video how Playwright's user-first locators like getByRole help to write more stable tests and improve your product user experience. Use nth() or filter() to select elements by their semantic surrounding elements, and avoid relying on implementation details to test your sites.

Learn in this video how to use environment variables with the Checkly CLI and your Monitoring as Code workflow.

Learn in this video how you can leverage Playwright's fixture to track Frontend JavaScript exceptions and fail your tests when there are errors in a page.

Learn how you can implement heartbeat monitoring of your scheduled server actions with Checkly.

Synthetic monitoring enables developers to simulate real user interactions to validate an application's performance and correctness. Checkly's Monitoring as Code offers a unique synthetic monitoring solution that enables you to control and automate your entire monitoring infrastructure in a single workflow.

Learn how to use Playwright's "toPass" method to create auto-repeating and asynchronous assertions.

Learn how the new Checkly features (code exporter and activity log) enable you to integrate Monitoring as Code into your Software Development Lifecycle. Define and debug your monitoring resources during development, test your preview deployments and start monitoring productions with ease.

Learn in this video how to use Playwright Test's test timeout feature to notice web performance regressions and how synthetic monitoring helps to avoid performance regressions over time.
