Where they talk about it

Quotes

  • no validated quote falls inside this feature's time range

Prerequisites mentioned

  • Enum extension of the test handler enum or the default test handler enum

Documented features match

  • Build extensible and data-driven AL test suites - medium confidence (llm). Docs say: General availability, roadmap id 573333. Handler registration
  • Product documentation: Create test codeunits and test methods, checked 2026-10-02. Both TestHandler and DefaultTestHandler are extensible system enums whose values map ITestHandler to implementing codeunits. Note: Section marked 'APPLIES TO: Business Central 2026 release wave 2 and later'; preview with prerelease runtime 18.

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.
