Video: Synthetic Monitoring and E2E Testing - 2 Sides of the Same Coin

Testing web applications with Playwright, a reliable end-to-end testing tool. Playwright offers fast execution, powerful tooling, and support for multiple languages. It provides precise selectors, web-first assertions, and code generation for easy testing. Playwright also offers features like live debugging, tracing, and running tests on CI. The future of Playwright aims to make testing easy and fun, with a focus on creating frustration-free web experiences.

Cypress is a powerful tool for end-to-end testing and API testing. It provides instant feedback on test errors and allows tests to be run inside the browser. Cypress enables testing at both the application and network layers, making it easier to reach different edge cases. With features like AppActions and component testing, Cypress allows for comprehensive testing of individual components and the entire application. Join the workshops to learn more about full circle testing with Cypress.

Playwright is a reliable end-to-end testing tool for modern web apps that provides one API, full isolation, fast execution, and supports multiple languages. It offers features like auto-weighting, retrying assertions, seamless testing of iframes and shadow DOM, test isolation, parallelism, and scalability. Playwright provides tools like VS Code extension, UiMode, and Trace Viewer for writing, debugging, and running tests. Effective tests prioritize user-facing attributes, use playwright locators and assertions, and avoid testing third-party dependencies. Playwright simplifies testing by generating tests, providing code generation and UI mode, and allows for easy running and debugging of tests. It helps in fixing failed tests and analyzing DOM changes, fixing locator mismatches, and scaling tests. Playwright is open source, free, and continuously growing.

Automated atomic tests are a great way to improve UI tests by making them less brittle and faster. The tests focus on testing a single feature or component and have minimal UI interactions. The Talk explores examples of automated atomic tests and their implementation on web applications. It also discusses the analysis of atomic tests, login tests, and working with JSON Web Tokens for authentication and authorization. The Talk concludes by highlighting the use of UI and web requests in automated atomic testing.

Component testing is a gray area between integration and unit testing. The demo app focuses on the cart component and writing test cases for Playwright component test and VTest. The first cart test encounters a bug with the invisible method in View Test.

This Talk discusses how to test mail service with Playwright, covering e-mail verification, reset password user journey, and more. It explores the use of third-party providers for reliable e-mail delivery and demonstrates how Playwright can help perform checks on e-mail content. The Talk also introduces the concept of a fake SMTP server and showcases how fixtures can be used to access the SMTP server and perform assertions on the HTML body of emails. Playwright's HTML rendering feature allows for interaction with email content as if it were a regular web page. It highlights the ability to render HTML from API calls, perform assertions on the rendered page, and exclude dynamically generated data from visual regression tests.
