Visual debugger for Rails system tests
Hey all, I've been working on this side project to get a Cypress.io-like experience, but for Ruby developers. It's plug-n-play with Capybara system tests, with the following features: - visualize assertions/commands as they happen - view all API requests, errors, and logs in the timeline - pause/continue on any step - rewind through history with a recorded video This is brand new, so looking for people to start trying it out and leave feedback.
In plain words
This visual debugger for Rails system tests integrates with Capybara to provide Cypress.io-like debugging capabilities for Ruby developers. It displays assertions and commands in real-time, shows API requests and errors in a timeline, and allows users to pause, continue, and rewind through recorded test videos. The tool works as a plug-and-play addition to existing system tests, helping developers visualize and troubleshoot their test execution.
