This video covers how to use Checkly's API checks and active synthetic monitoring to streamline your API monitoring process and detect issues faster. We'll set up a new API check to monitor one of Checkly's API endpoints and go step-by-step from configuring the API request to defining essential headers, monitoring details and retry strategies.

This webinar introduces an approach to visual regression monitoring, utilizing Playwright and Checkly. Playwright, an open-source end-to-end testing framework supported by Microsoft, enables you to simulate complex paths through your site. Checkly, which uses playwright to create synthetic service monitors, enables the execution of visual regression tests at regular intervals. This combination alerts developers to potential interface problems before they become visible to users.

Locating elements in your end-to-end tests can sometimes be a challenge. In this video, we tackle the problem of hard-to-locate elements by chaining multiple locators using `locator().and()`. By chaining locators you'll be able to combine user-first locators with specific locators reaching for a test id or CSS class.

In today's video, we explore a lesser-known feature of Microsoft's Playwright - API Testing. We'll illustrate how to use Playwright for testing GraphQL as an example of an HTTP-based API; RESTful APIs can be tested too. We'll explain the usage of the 'request' fixture with Playwright, parse responses and validate their correctness. Moreover, we'll delve into executing multiple API requests in a single Playwright test case while testing their responses.
