Breenix Integration Test Authoring

About

This skill provides a comprehensive framework for authoring integration tests within the Breenix kernel ecosystem. It guides developers through the process of implementing shared QEMU test patterns, defining checkpoint signals for serial output verification, and configuring specialized xtask commands. By standardizing kernel-side test code and CI workflows, it ensures that features are verified consistently and efficiently, reducing test execution time from minutes to seconds through optimized hardware emulation patterns.

Key Features

• Automated xtask command generation for complex test suites
• Shared QEMU instance patterns for rapid sequential testing
• 4 GitHub stars
• Custom GitHub Actions CI workflow templates for kernel testing
• Serial output checkpoint signaling for behavior verification
• Standardized kernel-side test modules with feature gating

Use Cases

• Implementing automated integration tests for new kernel subsystems
• Creating regression tests for verified kernel-space bugs
• Testing userspace program execution and syscall behavior
