Per `.planning/audit-2026-05-03/tests-audit.md` section 5, five
`XCTAssertTrue(true)` placeholder tests were identified across the tree
that are mathematically incapable of failing. This commit fixes or
removes each, conservatively. Files touched and disposition:
- App/Tests/AppTests/MCPRuntimeWiringTests.swift:260
fixed: replaced trailing `XCTAssertTrue(true)` rubber-stamp at end of
CR-02 channel-drain test with a load-bearing assertion that the drain
task completed via `finish()`, not cancellation. The implicit `await
drainTask.value` is the real gate; the new assertion ensures regressions
that cancel-instead-of-finish surface.
- App/Tests/AppTests/WebviewBundleLoadTests.swift:60
deleted: `test_assetsDirectoryGitignored_documentedInSmokeScript`. Body
was `XCTAssertTrue(true)` with comment "intentionally has no assertion
— it exists to document the split of responsibility". Documentation,
not a test. Replaced with a top-level comment block documenting the
same split (smoke-test-hud.sh is the runtime gate).
- packages/AgentCore/Tests/AgentCoreTests/ToolChoiceTests.swift:38
fixed: removed trailing `XCTAssertTrue(true) // Test compiles → contract
holds.` from `testLLMProviderStreamRequiresToolChoice`. The closure
body itself is the contract — if the test compiles, the contract holds.
Comment updated to make the compile-time semantics explicit.
- packages/Shell/Tests/ShellTests/InputMonitoringDenialTests.swift:36
deleted: `test_localMonitorOnlyFallback`. Body was `XCTAssertTrue(true)`
documenting that the real fallback test lives in HotkeyBindingTests.
Replaced with a top-level comment pointing readers there.
- packages/Vision/Tests/VisionTests/PackageBoundaryTests.swift:14
deleted: `testVisionModuleCompilesStandalone`. Body was
`XCTAssertTrue(true)` with comment "compile is the assertion." VISION-03
isolation is enforced by `scripts/check-vision-isolation.sh` and the
Package.swift dependency graph, both of which are real gates. Folded
the documentation into the `testPublicAPISurface` doc-comment so the
explanation isn't lost.
HudStateEnumTests rubber-stamps (audit items #4–6 in section 5) were
left as-is. The voiceOverLabel literals are user-facing accessibility
text that VoiceOver actually speaks; they are load-bearing in the sense
the audit calls out as worth preserving ("replace with behavioral
assertions if the literal under test is load-bearing"). A regression
that breaks an a11y label IS a real regression. Conservative read; not
worth the blast radius of guessing wrong.
Pre-existing baseline issues unrelated to this batch:
- `packages/Shell/Tests/ShellTests/InputMonitoringDenialTests.swift`
fails to COMPILE on a clean tree (MockProbe missing
`isListenEventAccessGranted()`). Verified via `git stash` that the
failure is independent of this commit. Not addressed here per the
scope rules — flagged for follow-up.
Net test count: -3 tests (3 deleted, 0 added — the
MCPRuntimeWiringTests assertion replaces the tautology in-place).
