How does it handle database tests?

The skill covers Ecto Sandbox configuration for concurrent testing and using ExMachina factories for clean test data setup.

What mocking library is recommended by this skill?

This skill focuses on Mox, which is the community-standard library for behavior-based mocking in Elixir.

Does this skill support Phoenix LiveView testing?

Yes, it includes comprehensive patterns for testing LiveView renders, events, form validations, and real-time PubSub updates.

Can I use this for property-based testing?

Absolutely, it provides templates and guidance for using StreamData to implement property-based tests in your Elixir project.

Security & Testing

Writes comprehensive, production-grade test suites for Elixir applications using ExUnit, Mox, and property-based testing patterns.

About

This skill provides specialized guidance for architecting and implementing robust test suites in Elixir. It covers everything from basic unit testing with ExUnit and advanced assertions to complex integration testing for Phoenix applications, including LiveViews and Channels. It also integrates patterns for database sandboxing, factory-based data setup, mocking external dependencies with Mox, and property-based testing with StreamData, ensuring your Elixir applications are resilient, concurrent-safe, and highly maintainable.
