SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Zig's testing workflows can be verbose; this skill guides agents through writing, organizing, and executing tests in Zig using zig test and zig build test, including comptime tests, leak detection via test allocators, and fuzz testing.

Core Features & Use Cases

  • Write and organize tests directly in Zig sources using test blocks and comptime checks.
  • Run tests with zig test or zig build test, apply test filters, and use the built-in fuzzing workflow to explore inputs.
  • Detect memory leaks and verify behavior in both unit and integration tests; example: validate a simple library function and ensure safety on edge cases.

Quick Start

Run zig test to execute all unit tests in your Zig project and review results.

FAQPage Schema
How do I run unit tests in a Zig project using zig build test?▼

Execute `zig build test` to compile and run all test blocks in your Zig project. This workflow validates behavior across your project and automatically reports any test failures encountered during execution, allowing you to verify code correctness efficiently.

How does comptime testing work in Zig?▼

Comptime testing in Zig uses compile-time checks to validate behavior before the program runs. By placing assertions inside comptime blocks, you catch logic errors during compilation, ensuring constraints are met without runtime execution overhead.

Can I detect memory leaks in Zig tests with a test allocator?▼

Yes, you can detect memory leaks in Zig by using a test allocator within your test blocks. The test allocator tracks allocations and verifies they are freed, ensuring your unit and integration tests validate memory safety on edge cases.

What is the best way to use fuzzing in Zig to explore edge cases?▼

The best way to use fuzzing in Zig is leveraging the built-in fuzzing workflow within `zig build test`. It automatically explores random inputs to detect memory leaks and validate behavior, ensuring safety on edge cases without writing manual test cases.

How do I filter specific test names when running zig test?▼

Filter specific test names by passing the test name as a command-line argument to `zig test`. This filters execution to only run matching test blocks, allowing you to target and verify individual unit tests without running the entire suite.
