To audit what each UI test actually exercises, every step now snapshots the live window to <TestFixtureName>/<TestName>_<NN>_<ShortDescription>.png: a booted frame (emitted automatically by TestHarness.BootAsync), one after each state-changing action, and one before each assertion. Flip ILSPY_TESTS_VISIBLE=1 to render the filmstrip; it lands under %TEMP%/ilspy-test-captures (overridable via ILSPY_TEST_CAPTURES). The step number and fixture/test name are derived automatically so inserting a breakpoint never renumbers the rest. The identity is recorded up front from the real ITest in an ITestAction hook rather than read live: NUnit's TestContext.CurrentContext does not flow onto async continuations, so a capture after an await would otherwise collide under the ad-hoc context. And when rendering is off the whole call is a true no-op -- not even a dispatcher pump -- so instrumenting a test can never perturb the navigation/tab timing it asserts on. Full headless suite stays green.pull/3755/head
