About this tag
The al testing tag on WindowsForum.com collects discussion of automated testing for AL, the language used to build extensions for Microsoft Dynamics 365 Business Central. Recent threads focus on Business Central 29, where Microsoft is adding data-driven AL test suites with reusable test data and shared lifecycle hooks for setup, cleanup, logging, measurement, and reporting. Coverage also follows ALTool's move toward command-line test automation, letting developers compile, deploy, and run AL test projects from scripts or CI/CD pipelines and return structured JSON results. Together these items track how AL testing is shifting away from manual runs and container workarounds toward repeatable, pipeline-friendly practices.
