Understanding Capybara Testing
Let’s start by understanding CapybaraTesting. So, Capybara offers developers to simulate a user on a web page as well as make assertions. Further, this is based on the content and environment of the page. Moreover, it also provides an API to interact with the web page. Not to mention, Capybara is a Ruby library (also known as a gem). In the same vein, it is useful with an underlying web-based driver. In addition, it consists of a user-friendly DSL (Domain Specific Language) which serves actions that execute the underlying web driver. Most importantly, if the page is loaded using the DSL (and underlying web driver). However, Capybara will attempt to locate the relevant element in the DOM (Document Object Model) and execute an action such as click button, link, etc. Nonetheless, various types of tests are exemplify with Capybara.
Above all, Capybara is helpful in testing web applications by simulating how a real user would interact with your app. However, it may be agnostic about the driver running your tests and comes with Rack::Test and Selenium support built in. WebKit also supports through an external gem.
