TestedBy and leaves the gaps empty (living scaffolding: the day a test is written and linked, it shows up by itself).
It is creation only: it never modifies or deletes an existing plan, suite or test. A name collision warns instead of overwriting, and a partial failure reports exactly what was created.
Choose the area path (and iteration)
Before creating, pick the area path (and optionally the iteration) the new plan will live under. Leave both empty and the plan is created under the project root. The lists come from the project’s classification nodes via the existingvso.work scope — no new permission — and you can always type a path by hand.
The “permission ≠ scope” 403
The most common creation failure is a 403 — you do not have the appropriate permissions to manage test plans under this area path.This 403 is not a scope problem.
vso.test_write is already granted — the error is an area-path ACL.The write permission
Creation requires thevso.test_write scope, added to the extension manifest by an administrator, which triggers an extension re-approval for the organisation. Until it is granted, the read-only analysis and export work fully — only creation is unavailable.
