End-to-End Testing, often abbreviated as E2E testing, is an automated testing strategy that validates an application’s performance and reliability from start to finish. It tests whether the flow of an application is functioning correctly, from start to end.
These tests often involve scripting headless browsers, as such interactions will require the regular performance of a system’s data integrity, APIs, databases, network connections, and other infrastructure. Unlike unit testing which focuses on a single ‘unit’ of code, E2E tests consider the application as whole.
E2E testing might involve actions like user login, navigation, mouse gestures, or data processing tasks. As well as in quality assurance, these tests play a crucial role in new feature development, when you want to ensure changes preserve existing behavior. E2E tests are most important for critical app functionality, such as authentication, checkout, and common interactions.
How can BrowserCat help with E2E testing?
BrowserCat works with industry standard testing libraries and common programming languages so that it fits perfectly into your development workflow. For example, you can write your tests locally using Playwright, then aim your tests at our servers for unlimited scale, speeding up your CI/CD pipelines and production testing frequency alike. As an added bonus, you don’t have to think about parallelization, hosting your own browsers, or ballooning costs ever again.
