Watir – web application testing in Ruby

Watir (Web Application Testing in Ruby, pronounced water), is an open-source family of Ruby libraries for automating web browsers.

Watir is a user focused way to test your websites. It mostly uses Selenium for browser automation, but it provides many more high level features that make it easy to write stable, maintainable tests.

Watir is designed for “Test Automation.” It takes the code in a page object and translates it into the series of applicable Selenium and JavaScript calls to accomplish the desired functionality. Watir attempts to understand the intention of the code in a test suite and tries to follow a “Do What I Mean” philosophy to accomplish it.

Watir project consists of several smaller projects. The most important ones are watir-classic, watir-webdriver and watirspec.

Features include:

  • Built-in libraries offering a good range of functionality.
  • Location web elements – there are different ways you can locate web-elements rendered inside the browser. The ones mostly used are id, class, tag name, custom attributes, label etc.
  • Taking Screenshots – take screenshot of the testing done as and when required. This helps to keep track of the intermediate testing.
  • Page Performance – measure page performance using the performance object which has properties like, performance.navigation, performance.timing, performance.memory and performance.timeOrigin. These details are obtained when you connect to the browser.
  • Page Objects – helps to reuse the code in the form of classes. Using this feature, we can automate our app without having to duplicate any code and also make it manageable.
  • Downloads – easy to test file download for UI or website.
  • Alerts – provides easy to use APIs to test alerts popup in your UI or website.
  • Headless Testing – using headless testing,the details are obtained at the command line without having to open the browser. This helps to execute UI test cases at the command line.
  • Supports all modern web browsers.
