Capybara vs TestNG: What are the differences?
Capybara: 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; TestNG: A testing framework inspired from JUnit and NUnit. It is a testing framework designed to simplify a broad range of testing needs, it covers all categories of tests: unit, functional, end-to-end, integration, etc.Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc.
Capybara and TestNG can be primarily classified as "Testing Frameworks" tools.
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, TestNG provides the following key features:
- Support for data-driven testing
- Support for parameters
- Powerful execution model (no more TestSuite)
Capybara is an open source tool with 8.87K GitHub stars and 1.3K GitHub forks. Here's a link to Capybara's open source repository on GitHub.
