How are test functions discovered in Gleam?

The skill follows Gleeunit conventions where any public function ending in '_test' within the test directory is automatically discovered and executed.

Does this skill support the deprecated 'should' module?

No, this skill strictly enforces the modern 'let assert' syntax as per current Gleam best practices to ensure your code remains future-proof.

Can I run tests for both Erlang and JavaScript targets?

Yes, the skill provides specific commands and configuration patterns for running tests on both the Erlang and JavaScript runtimes.

Does it support advanced testing like snapshot or property-based tests?

Yes, it includes comprehensive guidance for using Birdie for snapshot testing and QCheck for property-based testing.

Security & Testing

Guides the creation of robust Gleam test suites using gleeunit and modern idiomatic assertion patterns.

About

The Gleam Testing skill empowers Claude to architect comprehensive test suites for Gleam projects, ranging from simple unit tests to complex property-based and snapshot testing. By enforcing the latest Gleam standards—specifically the mandatory use of 'let assert' over deprecated modules—it ensures codebases remain idiomatic and reliable across both Erlang and JavaScript targets. It provides specialized patterns for OTP actors, web applications, and database integrations, making it an essential tool for developers aiming for high-quality, production-ready Gleam code.
