TestCafe vs Cypress: Core Differences

Why compare Testcafe vs Cypress?

Cypress

Cypress Features

  • 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

  • Programming Language: Cypress supports only JavaScript/Typescript as a programming language.
  • 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 .
  • Assertion Libraries: Cypress supports only Mocha, Chai assertion libraries. However these are sufficient for most test scripts.

TestCafe

TestCafe Features

  • 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.
  • Fast and Stable: Because a test is executed inside a browser, the tests are faster compared to other frameworks. Tests are also more stable as events are simulated internally using JavaScript.
  • 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

  • Programming Language: Testcafe supports only Javascript/Typescript programming language.
  • Assertion Libraries: TestCafe supports built-in assertion libraries only.
  • By default, TestCafe supports only Selector Support 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.
