This Skill provides comprehensive guidance on running tests, understanding coverage, and troubleshooting common issues in the Rails application. It helps you quickly diagnose and resolve test failures, particularly intermittent system test issues, ensuring your application remains robust.
HeatScheduler, Entry model, and Table model.Use the testing skill to run all system tests for the Rails application and provide instructions if they fail due to asset routing errors.
High-intent search queries and answers about installing and using this skill.
Run Rails tests using `rails test` for unit and integration tests, or `rails test:system` for system tests with Capybara. Generate coverage reports by running tests with coverage tooling to identify which application components like HeatScheduler, Entry model, and Table model are tested.
Intermittent system test failures often stem from race conditions in Capybara and Selenium interactions. Common culprits include asset routing errors and timing issues. Rerun failed tests and check asset configuration in your test environment to resolve these issues.
Yes, Capybara and Selenium are standard tools for Rails system tests. They enable browser-based testing of user interactions, fixtures, and assets. This Skill covers troubleshooting common Capybara and Selenium issues in Rails applications.
Asset routing errors occur when system tests cannot locate CSS, JavaScript, or image files. Configure your test environment to properly serve assets, and refer to Rails test asset guidance. This Skill provides specific troubleshooting steps for resolving these errors.
Unit tests verify individual model and component logic; integration tests check interactions between components; system tests use Capybara to simulate real user browser interactions. Rails provides `rails test` for units and integrations, `rails test:system` for system tests with fixtures.
