Capture Browser Console Logs in Rails System Tests with Capybara and Cuprite · Daniela Baron

When writing Rails system tests, a common practice is to use Capybara to simulate user interactions. If the front end is a JavaScript-heavy Single Page Application (SPA), this also requires installing and configuring a JavaScript driver for Capybara, such as Cuprite, to test JavaScript execution in the browser. When testing a SPAs, it can be challenging to understand how different pieces of code are interacting or when certain code is executing. In cases where unexpected behavior arises during test execution, such as event handling issues or timing problems, adding console.log statements at strategic points in the front-end code can help. But how do you capture and view those logs while running Rails system tests?.
