Learn in this video how to monitor network HTTP calls in your end-to-end tests and use Playwright's "waitForResponse" method to capture specific network responses. This approach allows you to wait for specific API calls to validate if you website or app shows the correct data.

We need to monitor our service's performance, but large closed SaaS options are expensive and complex. OpenTelemetry is the 'wave of the future' for observability, but is it ready for your team? Yes! Join Nočnica to see a demonstration of instrumenting a demo application and learn what OpenTelemetry can do. We'll also add external site monitors with Checkly synthetics checks.

In this video, you will learn how to leverage Checkly's parallel scheduling feature to simultaneously monitor and test all your essential production targets. This knowledge will help you reduce your mean time to detect outages, assess whether production problems are regional or global, and enhance your monitoring data granularity.

Sometimes, applications can behave differently even though your users do the same things. How can you test these non-deterministic flows? Learn in this video how Playwright's "locator.or()" method helps to write tests that can handle different application flows.

Checkly now supports Visual Regression Testing (VRT) with Playwright's `toHaveScreenshot` method. Add a single assertion to your browser checks and include VRT in your sites' and apps' global monitoring.

Learn in this video how you can use custom webhooks and Checkly heartbeat checks to monitor scheduled deployments on Netlify, Vercel and other platforms. Never let a broken deployment pipeline go unnoticed.

Learn in this video how you can use Playwright's debug and UI mode, "page.pause()" and Playwright's VS Code extension to debug your end-to-end tests.

Learn in this video how Playwright codegen gives your synthetic monitoring a head start. Create a new Checkly browser check, record your script and start monitoring your sites from around the world.

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!
