Rspec Coder

This skill teaches core Ruby patterns including classes, modules, inheritance, and mixins alongside functional programming with blocks, procs, and lambdas. It covers enumerable operations, lazy evaluation, and metaprogramming techniques like method_missing and dynamic method definition, plus error handling strategies and RSpec testing.

Test Inertia Rails controller actions with RSpec matchers that verify rendered components, props, flash messages, and deferred data. Always use matchers like `render_component` and `have_props` instead of direct property access, and remember to call `follow_redirect!` after POST/PATCH/DELETE before asserting flash or props.

React Coder builds functional React components using TypeScript, hooks, and current best practices for clean, maintainable code. It handles component patterns, type-safe props with generics, and performance optimization techniques like memoization and code splitting.

This skill enables you to automatically generate Capybara acceptance tests for web applications, streamlining your test automation workflow. Built by LambdaTest (now TestMu AI), it simplifies the process of creating robust browser-based test scenarios without manual coding overhead.

Ruby Patterns covers essential idioms and architectural approaches for Rails and Ruby development. Learn blocks, procs, lambdas, modules, metaprogramming techniques, pattern matching, and enumerable chains alongside testing strategies with RSpec, error handling patterns, and project structure conventions for gems and Rails apps.

Pytest Coder generates test files following pytest best practices including the AAA pattern, fixtures, parametrization, and mocking. It handles unit and integration testing, async code, and exception cases while maintaining test isolation and descriptive naming conventions.
