It is built for the modern web and aims to address the pain points developers or QA engineers face while testing an application. Cypress is a developer-friendly tool that uses a unique DOM manipulation technique and operates directly in the browser. It also provides a unique interactive test runner.
Cypress is fundamentally built on a different architecture compared to Testcafe. It supports different types of testing:
End to End Testing
Time Travel: Cypress runs on its own window and takes snapshots while tests run. Hover over commands in the Command Log to see exactly what happened at each step.
Debuggability: Cypress allows direct debugging from Developer Tools. Readable errors and stack traces make debugging fast and efficient.
Automatic Waiting: In Cypress, testers do not need to provide Explicit Wait. Cypress automatically waits for commands and assertions before moving on. No more async hell.
Spies, Stubs, and Clocks: This feature helps to verify and control the behaviour of functions, server responses, or timers.
Network Traffic Control: Easily control, stub, and test edge cases without involving the server. Stub network traffic as it is required.
Consistent Results: Since Cypress uses its own browser control strategy, it is comparatively faster, more consistent, and enables reliable tests that are flake-free.
Screenshots and Videos: Screenshots are taken automatically on failure. One can take videos of the entire test suite when run from the CLI.
Cross browser Testing: Cypress supports running tests within New Edge, Firefox, and Chrome-family browsers.
Limitations of Cypress
Multiple Tab: Cypress does not support multiple tabs or allow switching between Parent and Child windows.
Native Mobile Apps: Cypress does not support native mobile apps automation.
IFrame Support : Cypress support for iframe is limited.
Parallel Test Execution: Cypress doesn’t support parallel testing on the same or multiple browsers.
Single Origin Tests: Testers cannot create tests under different origins or URLs. It must always be inline with single origins.
Selector Support: Cypress supports only CSS selectors natively but there are third party packages which can be pluggable with Cypress to use XPath.
Assertion Libraries: Cypress supports only Mocha, Chai assertion libraries. However these are sufficient for most test scripts.
Super Easy setup: TestCafe is easy and quick to set up. Anyone who knows the basics can do it on their own.
No third-party dependency: TestCafe doesn’t depend on any third-party libraries like webdriver, or external jars etc.
Easy Test Script writing: TestCafe command chaining techniques make teams more productive. 20 lines of code in other frameworks can be just written in 10 to 12 lines using TestCafe syntax.
Mock Requests: TestCafe helps to emulate HTTP responses to feed sample data to an app, troubleshoot connectivity errors, and cheat downtime.
Multiple Tab Support: Unlike Cypress, Testcafe provides functionalities like switching between windows and multiple tab support.
iframe Support: Testcafe supports iframes and one can switch to and from iframes in their tests.
Parallel Testing: With concurrency mode enabled, TestCafe tests can be run in parallel.
Automated Waiting: TestCafe waits automatically for elements to appear. There’s no need to insert External Waits.
Cross Browser Testing: Testcafe supports all major browsers like old and new Edge, Firefox, IE, and all Chrome family browsers.
Debuggability: Testcafe provides Live Mode which helps to visualize individual actions on the browser for easier debugging.
Screenshots: TestCafe supports taking screenshots for tests using built-in screenshot commands.
Limitations of TestCafe
Assertion Libraries: TestCafe supports built-in assertion libraries only.
Selector Support: By default, TestCafe supports only CSS selectors.
Execution of Tests: Browsers are not aware that they are running in test mode. So, in some edge cases, automation control can be disrupted. It’s also quite hard to debug possible issues.
