Capybara vs Robolectric: What are the differences?

Developers describe Capybara as "Acceptance test framework for web applications". Capybara helps you test web applications by simulating how a real user would interact with your app. It is agnostic about the driver running your tests and comes with Rack::Test and Selenium support built in. WebKit is supported through an external gem. On the other hand, Robolectric is detailed as "An open-source testing framework for Android". It is a framework that brings fast and reliable unit tests to Android. Tests run inside the JVM on your workstation in seconds. Test drive your Android application with robolectric.

Capybara and Robolectric belong to "Testing Frameworks" category of the tech stack.

Some of the features offered by Capybara are:

  • No setup necessary for Rails and Rack application. Works out of the box.
  • Intuitive API which mimics the language an actual user would use.
  • Switch the backend your tests run against from fast headless mode to an actual browser with no changes to your tests.

On the other hand, Robolectric provides the following key features:

  • Test APIs & Isolation
  • Run Tests Outside of the Emulator
  • SDK, Resources, & Native Method Simulation

Capybara and Robolectric are both open source tools. Capybara with 8.87K GitHub stars and 1.3K forks on GitHub appears to be more popular than Robolectric with 4.63K GitHub stars and 1.19K GitHub forks.
