In this article, we’ll demonstrate how to create End-to-End (E2E) UI tests for the e-commerce platform ASOS across three of their markets (UK, IT, DE) in less than 30 minutes.

Why Use TestCafe for Running Tests?

For this tutorial, we’ll be using the TestCafe framework. TestCafe is an open-source framework that evolved from a commercial product, offering several advantages over WebDriver-based frameworks:

  • Simplified Setup: TestCafe eliminates the need for WebDriver, avoiding compatibility issues between WebDriver and browser versions.
  • Faster Execution: Tests run significantly faster compared to WebDriver-based tests.
  • Clear Error Reporting: TestCafe provides precise error messages when a test fails, unlike WebDriver-based frameworks that often offer ambiguous error messages.
  • Ease of Implementation: Once the initial setup is complete, implementing tests is straightforward, providing a high return on investment (ROI).
  • JavaScript-Based: TestCafe uses JavaScript, making it accessible and easy to use for front-end developers.
