Data-driven tests
Data-driven tests
One test procedure can run against many data sets from a test data source, so more tests come from adding data points. The platform runs the test once for every entry, building the data on demand.
Area: Developer tools. Status: GA. Developer relevance: high. Airtime: 4 min across 2 videos, demoed.
Status evidence
- Nothing said about status; launch event convention: generally available unless stated otherwise.
Where they talk about it
- What's new in AL and Tools: 20:32 to 23:29, demo at 22:07 (called "Data-driven tests (test data source)" there)
- What's new: Testability Enhancements: 0:32 to 1:13, demo at 1:13 (called "Data-driven testing in AL" there)
Quotes
- 1:03 "we can broaden our test um scope to such an extent that we gain the trust uh and confidence in our AI features" - States the main reason for data-driven testing: wider test coverage for AI features.
- 21:29 "run the whole suite from the command line and get structured JSON with pass fail and skip counts plus a real exit code" - Gives the concrete CI outcome: structured results and an exit code that fails the build.
- 23:12 "So for every single entry that exists in this data set, this platform will execute this test and provide the result for it." - Explains how data-driven tests run: one test method executes once per data set entry.
Caveats mentioned
- Only the new syntax is shown here; a dedicated session in the launch event covers data-driven testing in depth
Prerequisites mentioned
- A data test source implementing the list of test cases
Documented features match
- Build extensible and data-driven AL test suites - high confidence (llm). Docs say: General availability, roadmap id 573333. Parameterized tests from data sources
Docs checked on 2026-10-02: the match is against Microsoft's what's new pages for the wave as they were on that date. Microsoft keeps filling the documentation, so "no documented item" can go stale. The wider product documentation on learn.microsoft.com was searched for this feature on the same date; the feature's data lists an article when one was found.
