What problem does it solve? AL/Business Central development lacks a unified local build-and-test gate: compiling with the right analyzer set, publishing to a Docker container, and running both unit and integration tests normally require manual, error-prone steps. This Skill runs the entire gate in one command and returns a structured pass/fail report. ## Core Features & Use Cases - Canonical build/test gate: Runs compilation with Microsoft and ALCops analyzers, publishes apps to a branch-scoped BC Docker container, and executes container tests plus AL Runner unit tests, writing JUnit XML results and a machine-readable summary.json. - Fast inner-loop unit testing: The -UnitTestOnly mode compiles all apps through the analyzer gate and runs AL Runner tests without needing a container, supporting RED-GREEN TDD cycles. - Breaking-change detection: Optionally caches the previous release as an AppSourceCop baseline so breaking changes surface as AS00xx compile diagnostics in every gate run. - Use Case: After modifying AL code, ask the agent to run the build gate; it delegates to a subagent that executes test.ps1 and returns a verdict with per-runner test counts, failing test names, and telemetry file paths. ## Quick Start Ask the agent to run the al-build gate to verify your AL changes compile and all tests pass before committing.
