What

The source/api and source/telemetry half of #985, re-applied on current main. #985 had drifted too far to rebase (parts shipped in #988, #989, #993, #1007 and #1008, five files conflicted, and three tests failed against main's Clerk.auth routing). This PR carries over only the API test changes that still apply, and adapts the three that broke.

Only test files change. There are no production code changes.

Why each change now fails on a regression

Switched-off tests turned back on

  • PasskeyCreationServiceTest (@Ignored on main) is rewritten to assert the submitted credential JSON, the returned passkey and the exact error types. Before, 8 of 9 tests depended on an unmocked Clerk.session and a faked serializer.
  • PasskeyAuthenticationServiceTest's sign-in test is back on and asserts the strategy, challenge, rpId and attempt parameters.
  • SSOServiceTest (@Ignored on main, and its tests exercised nothing) is replaced with tests for nonce sign-in, sign-up redirects, the sign-up→sign-in transfer, create and prepare failures, and a callback with no flow in progress.

Assertions that couldn't fail

  • ClerkTest: the "environment not initialized" tests installed a mock environment, so the real null fallback never ran.
  • ClerkApiResultConverterFactoryTest only asserted non-null. It now checks the type is wrapped and unwrapped.
  • DeviceAttestationHelperTest: the "uses cache" test compared two results of a deterministic hash. The "scope configured" test asserted that a non-null val was non-null.
  • ExternalAccountServiceTest never set up a connection in progress, so the code under test never ran.
  • PasskeyCredentialManagerTest had a try/catch that swallowed every failure.
  • PasskeyHelperTest keeps main's getDomain tests (fix(passkeys): strip only a leading www. from the fallback rpId #1007). The GetPasskeyRequest test now checks the encoded WebAuthn JSON instead of reading back constructor arguments, and the data-class getter test is removed.

Tests that would survive a revert

  • SessionTokenFetcherTest: the skipCache test had an empty cache, so it still passed when skipCache was ignored.
  • OrganizationMembershipTest granted every permission at once, so a miswired can* helper still passed. Permissions are now granted one at a time.
  • SignInAuthenticateWithRedirectTest was failing for an unrelated "Clerk must be initialized" reason.
  • SSOManagerActivityTest asserted RESULT_CANCELED, which is an Activity's default result. It now also checks for uncaught exceptions, that the service was called, and that the activity finishes.
  • SignOutServiceTest: the refresh test now checks that the device token and session are cleared before the refresh, and that the refreshed client is applied.
  • NativeMagicLinkServiceTest now checks that the PKCE verifier matches the prepared challenge, that the client is updated, and that the pending store is cleared.
  • GoogleSignInServiceTest now checks that no sign-up is created for a non-transferable missing account, or for a different sign-in error. Both verify Clerk.auth.createSignUp, the call production makes. Removing the transferable guard fails the first test, and removing the external_account_not_found check fails the second.
  • BiometricCredentialsTest: the cancelled-enrollment rollback test threw CancellationException from a fake without cancelling anything, so it still passed with NonCancellable removed. It now cancels the job for real. A companion test covers a failing server revoke.
  • ClerkTelemetryEnvironmentTest now checks that each value is read live from its injected provider and that an empty publishable key is treated as missing. Before, it only checked the constructor shape.

Flakiness and isolation

  • ClerkOfflineCacheTest and the biometric file-lock test no longer race on delay/Thread.sleep.
  • Teardown is added for Main-dispatcher, Clerk.environment, credential-manager and StorageHelper state that leaked between classes.
  • ClerkOfflineCacheTest still reads initializationRetryJob by reflection. A test hook would mean widening two private fields on Clerk and ConfigurationManager in production code, which this test-only PR avoids.

Removed tests that could never fail

  • NetworkConnectivityMonitorTest: "initial connectivity state is true by default" called resetForTesting(), which sets the value to true, and then asserted it was true.
  • PasskeyServiceTest: "large credential list" repeated the delegation test with 100 IDs. signInWithPasskey passes the list through unchanged, so its size reaches no other code path.

Adapted to main

  • SSOServiceTest: main now reports failures through Clerk.auth.reportingFailures, so the strict mockk<Auth>() hit Auth.emitAuthError. The mock stays strict, emitAuthError is stubbed with justRun, and both failure tests now verify the failure is reported exactly once. A mutation check (never emitting in reportingFailures) fails both tests.
  • SSOServiceCancellationTest: in "stale completion that succeeds…", the stub moves from SignUp.create(Transfer) to SignUpApi.createSignUp, because main routes through Clerk.auth.createSignUp. A mutation check (making finishPendingAuth always clear the current flow) fails this test and the existing stale-completion test.
  • AuthTest drops its signInWithOtp email test, which duplicates AuthOtpTest. That test now also asserts that the created SignIn is returned.

Results

  • :source:api:testDebugUnitTest (rebased onto main at 1385b1f): 882 run, 0 failed, 2 skipped. On main, the three @Ignored classes above are skipped.
  • :source:telemetry:allTests: 11 run, 0 failed.
  • spotlessApply, :source:api:detekt and :source:ui:detekt are clean.

Open question (production code not changed)

PasskeyCreationService.kt:112 builds PublicKeyCredentialData(rawId = …). That data is serialized with ClerkApi.json, which uses snake_case naming, so registration sends raw_id where WebAuthn specifies rawId. This only matters if the server doesn't accept raw_id. It needs someone to confirm what FAPI expects before we change it.

The passkey test may miss a payload field-name regression, but the server’s required spelling is not yet confirmed. This is a bounded coverage risk to clarify; the Google sign-in assertion concern is resolved.

105-107: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Assert each credential descriptor's type.

The test checks each serialized id but does not check type. If serialization drops or changes type, this test still passes. WebAuthn requires type in each credential descriptor. Assert that both serialized descriptors retain "type": "public-key". (w3.org)

Carries over the source/api and source/telemetry test changes from #985 that
still apply to main. Re-enables PasskeyCreationServiceTest and the switched-off
PasskeyAuthenticationServiceTest/SSOServiceTest cases, replaces assertions that
could not fail (non-null checks, default Activity results, empty caches,
all-permissions-at-once) with checks on the actual params, results and errors.

Adapts the SSO tests to main's Clerk.auth routing: SSOServiceTest stubs and
verifies Auth.emitAuthError, and the stale-completion cancellation test stubs
SignUpApi.createSignUp instead of SignUp.create.
