Cypress is an open-source testing framework specifically designed for testing modern JavaScript applications. It allows you to write end-to-end tests that are fast, easy to maintain, and reliable. Cypress provides a powerful yet simple API for writing integration tests as well as unit tests. It also supports mocking of requests, automatic waiting for elements to appear on the page, and other features that make it easier to test your application.

Fighting Test Flakiness with Time Machines
The Talk discusses the importance of learning from the past in software testing and troubleshooting test flakiness. It highlights the challenges of using memory and communication to gather information. The introduction of Replay.io, a time-traveling debugger, is proposed as a solution. The benefits of using Replay Chromium for recording and debugging, as well as the features of the Replay debugger, are emphasized. The Talk also addresses the relationship between test flakiness and app flakiness, and the significance of simulating real-world scenarios in testing.

The web has evolved. Finally, testing has also. Cypress is a modern testing tool that answers the testing needs of modern web applications. It has been gaining a lot of traction in the last couple of years, gaining worldwide popularity. If you have been waiting to learn Cypress, wait no more! Filip Hric will guide you through the first steps on how to start using Cypress and set up a project on your own. The good news is, learning Cypress is incredibly easy. You'll write your first test in no time, and then you'll discover how to write a full end-to-end test for a modern web application. You'll learn the core concepts like retry-ability. Discover how to work and interact with your application and learn how to combine API and UI tests. Throughout this whole workshop, we will write code and do practical exercises. You will leave with a hands-on experience that you can translate to your own project.

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.

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.

You probably know the story. You’ve created a couple of tests, and since you are using Cypress, you’ve done this pretty quickly. Seems like nothing is stopping you, but then – failed test. It wasn’t the app, wasn’t an error, the test was… flaky? Well yes. Test design is important no matter what tool you will use, Cypress included. The good news is that Cypress has a couple of tools behind its belt that can help you out. Join me on my workshop, where I’ll guide you away from the valley of anti-patterns into the fields of evergreen, stable tests. We’ll talk about common mistakes when writing your test as well as debug and unveil underlying problems. All with the goal of avoiding flakiness, and designing stable test.

From Good to Great: Elevate Testing with Cypress Contract Tests
This Talk discusses the challenges of testing multiple services in a microservices architecture and introduces the use of Cypress and Pact to address these challenges. It explains how to use Cypress to write a contract and generate and share it with the provider. The verification process and CI workflow for the consumer and provider are also discussed. The Talk emphasizes the importance of contract testing to ensure seamless communication between microservices.

The Talk discusses the differences between Cypress component testing and React Testing Library (RTL). It highlights the benefits of using Cypress Component Testing, such as easier handling of complex components and a more stable testing experience in CI. The comparison between SignOn and Jest focuses on low-level spying and mocking capabilities. The comparison between Cypress Intercept and Mock Service Worker (MSW) examines their network spy and mocking capabilities. The Talk also emphasizes the superior developer experience and observability provided by Cypress component testing compared to RTL.

Gaining Confidence with Cypress Tests
Welcome to React Advanced London where we'll learn about gaining confidence with Cypress tests. We'll explore browser testing, including tests for specific units of work, business services, APIs, and components using different tools. Cypress provides selectors for easy object selection in tests. We learned how to select objects in our tests and rerun them to check for successes and failures. We also discussed best practices for Cypress tests, including using data-cy elements, commands, mocks, and fixtures.
