Why Cypress sucks for end-to-end tests in 2025

End-to-end (E2E) testing is a vital part of software development, ensuring that applications operate as intended from the user's perspective by providing comprehensive coverage and reducing risk. Cypress, an open-source testing framework developed by Cypress.io, is primarily used for E2E testing of web applications and offers a developer-friendly environment with features such as fast setup, real-time reloads, and an interactive test runner for efficient debugging. Cypress supports JavaScript and runs directly in the browser, allowing for accurate test execution by accessing the DOM, network requests, and browser behavior. It uses JavaScript for scripting, Chai for assertions, and supports various element locators to interact with and validate web elements, making it a versatile tool for simulating user actions and verifying application states. However, there is a suggestion that by 2025, its usefulness may be limited, although the reasons for this are not detailed.
