Purpose

Add end-to-end integration test coverage for identity flow executors whose routing, rejection, provisioning, and fail-closed behavior cannot be adequately verified using mocked unit
tests.

The tests cover 20 scenarios across:

  • Attribute uniqueness validation, including conflicts, retry behavior, blank attributes, persistence, and absence of partial writes.
  • User type resolution using executor-level allowedUserTypes restrictions and malformed configuration fallback.
  • Login-or-register routing for known, unknown, and ambiguous identities.
  • Identity disambiguation by organization unit and user type, including incorrect-password rejection and fail-closed behavior.
  • Federated user provisioning based on application-allowed user types, self-registration eligibility, ambiguity, and resolved organization units.

These tests verify observable behavior through the running server, including flow status, prompts, structured errors, assertions, persisted users, credential confidentiality, and
absence of unintended side effects.

This PR does not introduce breaking changes or modify production behavior.

Approach

The integration tests create isolated fixtures through the ThunderID management APIs, including organization units, user types, users, flows, applications, and identity providers.

Key implementation decisions include:

  • Constructing realistic registration and authentication flow graphs around the executors under test.
  • Exercising flows through the /flow/execute API instead of invoking executor implementations directly.
  • Using isolated authentication flows for custom registration flows to avoid unrelated flow compatibility failures.
  • Using distinct user passwords and validating JWT identity claims to prove that disambiguation selects and authenticates the intended account.
  • Running federated provisioning scenarios through a mock Google OIDC server and the complete authorization redirect and callback flow.
  • Verifying successful behavior through both flow responses and persisted user state.
  • Verifying rejection behavior through exact flow outcomes, error codes, returned prompts, empty assertions, and absence of newly created users.
  • Tracking and removing all test-created resources during suite teardown.
  • Extending the integration response model to expose i18n message parameters required to validate the conflicting attribute reported by the uniqueness validator.

The following focused integration suites were executed successfully:

  • TestAttributeUniquenessTestSuite
  • TestUserTypeResolverRuntimeTestSuite
  • TestLoginOrRegisterTestSuite
  • TestUserDisambiguationTestSuite
  • TestFederatedProvisioningTestSuite

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to b3224

The PR adds end-to-end identity-flow tests, but parallel runs may fail nondeterministically because packages share a fixed mock port and fixture identifiers, while teardown ordering can leave resources behind; one disambiguation scenario also does not assert the claimed incorrect-password rejection. These bounded test reliability and coverage issues should be fixed or explicitly accepted before merge.

149-167: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Delete the applications before the flows in TearDownSuite.

The loop at Lines 149-153 deletes the flows first. The applications created by appForResolverFlow still reference those flows at that point. If the server rejects deletion of an in-use flow, the error is only logged, and the flow row stays. The next run then hits a duplicate flow handle (reg_flow_resolver_narrowed, reg_flow_resolver_bad_prop) or a duplicate client ID and fails in SetupSuite.

Move the application cleanup ahead of the flow cleanup.

366-391: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add the rejected-password step, or correct the comment claim.

The comment at lines 366-367 states the resolution is "proven by only that account's password authenticating". The test submits only ts.passwordB and asserts COMPLETE. It never submits ts.passwordA, so the negative half is not verified. If userType disambiguation were ignored and credential authentication re-resolved by email plus password, ts.passwordB would still succeed and this test would still pass.

TestResolveDisambiguatesByOUHandle covers that negative case for the same user pair, so the gap is narrow. Add the symmetric rejection step to close it, and consider validating the assertion claims for type B as that test does for OU A.

♻️ Proposed symmetric rejection step
 	ts.Require().True(common.HasInput(flowStep.Data.Inputs, "password"),
 		"Resolving to a single account must proceed to the password prompt")
 
+	// The other account's password must be REJECTED, mirroring the ouHandle scenario.
+	rejected, err := common.CompleteFlow(flowStep.ExecutionID,
+		map[string]string{"password": ts.passwordA}, "action_pwd", flowStep.ChallengeToken)
+	ts.Require().NoError(err, "Failed to submit the non-selected account's password")
+	ts.Require().Equal("INCOMPLETE", rejected.FlowStatus,
+		"The type-A account's password must not authenticate the type-B account")

and the mock server’s authorizeFunc closure. Update the shared field and its
read in federatedLogin and the closure registered through SetAuthorizeFunc to
use a mutex, or register a per-login closure that captures the email by value,
while preserving the existing authorization behavior.

- Around line 343-349: Update the rejected-password assertion in the
authentication flow test to require an exact FlowStatus of INCOMPLETE instead of
merely checking it is not COMPLETE, preserving the subsequent ability to resume
the same execution and retaining the existing assertion message context.

In `@tests/integration/flow/registration/attribute_uniqueness_test.go`:
- Around line 20-45: The integration suite uses fixed server-side identifiers
that can collide across runs. Generate a single run-specific suffix in
SetupSuite and apply it consistently to uniquenessOU.Handle, both user-type
names, flow handles, ClientID, and the isolated auth-flow handle, ensuring all
related fixture references use the suffixed values.
