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.

Testing is hard, testing takes time to learn and to write, and time is money. As developers we want to test. We know we should but we don't have time. So how can we get more developers to do testing? We can create better tools.Let me introduce you to Playwright - Reliable end-to-end cross browser testing for modern web apps, by Microsoft and fully open source. Playwright's codegen generates tests for you in JavaScript, TypeScript, Dot Net, Java or Python. Now you really have no excuses. It's time to play your tests wright.

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.

We send emails to our users - account verification and newsletters. We allow the user to contact us by sending an email via inbuild form. Do we? Does the user receive an account verification email or exactly what notification they signed up for? We can cover this functionality as part of E2E tests: get an email and open it to check what is in it. We will need Playwright and a fake SMTP server to capture emails sent by the app.
