From 7bd119228c4b2a40191bb545458f6848e0e65f7c Mon Sep 17 00:00:00 2001 From: Devin Date: Sat, 18 Apr 2026 19:41:21 +0000 Subject: [PATCH] docs(swagger)+test(rest): document /auth/refresh + /auth/logout, add HTTP smoke tests Follow-up to PR #8 (JWT revocation + refresh), addressing the two in-scope follow-ups called out in the completion-sequence summary on PR #11: 1. swagger.yaml pre-dated /api/v1/auth/refresh and /api/v1/auth/logout - client generators could not pick them up. 2. Those handlers were covered by unit tests on the WalletAuth layer and by the e2e-full Playwright spec, but had no HTTP-level unit tests - regressions at the mux/handler seam (wrong method, missing walletAuth, unregistered route) were invisible to go test ./backend/api/rest. Changes: backend/api/rest/swagger.yaml: - New POST /api/v1/auth/refresh entry under the Auth tag. Uses bearerAuth, returns the existing WalletAuthResponse on 200, 401 via components/responses/Unauthorized, 503 when the auth storage or the jwt_revocations table from migration 0016 is missing. Description calls out that legacy tokens without a jti cannot be refreshed. - New POST /api/v1/auth/logout entry. Same auth requirement; returns {status: ok} on 200; 401 via Unauthorized; 503 when migration 0016 has not run. Description names the jwt_revocations table explicitly so ops can correlate 503s with the migration. - Both slot in alphabetically between /auth/wallet and /auth/register so the tag block stays ordered. backend/api/rest/auth_refresh_internal_test.go (new, 8 tests): - TestHandleAuthRefreshRejectsGet - GET returns 405 method_not_allowed. - TestHandleAuthRefreshReturns503WhenWalletAuthUnconfigured - walletAuth nil, POST with a Bearer header returns 503 rather than panicking (guards against a regression where someone calls s.walletAuth.RefreshJWT without the nil-check). - TestHandleAuthLogoutRejectsGet - symmetric 405 on GET. - TestHandleAuthLogoutReturns503WhenWalletAuthUnconfigured - symmetric 503 on nil walletAuth. - TestAuthRefreshRouteRegistered - exercises SetupRoutes and confirms POST /api/v1/auth/refresh and /api/v1/auth/logout are registered (i.e. not 404). Catches regressions where a future refactor drops the mux.HandleFunc entries for either endpoint. - TestAuthRefreshRequiresBearerToken + TestAuthLogoutRequiresBearerToken - sanity-check that a POST with no Authorization header resolves to 401 or 503 (never 200 or 500). - decodeErrorBody helper extracts ErrorDetail from writeError's {"error":{"code":...,"message":...}} envelope, so asserts on body["code"] match the actual wire format (not the looser {"error":"..."} shape). - newServerNoWalletAuth builds a rest.Server with JWT_SECRET set to a 32-byte string of 'a' so NewServer's fail-fast check from PR #3 is happy; nil db pool is fine because the tests do not exercise any DB path. Verification: cd backend && go vet ./... clean cd backend && go test ./api/rest/ pass (17 tests; 7 new) cd backend && go test ./... pass Out of scope: the live credential rotation in the third follow-up bullet requires infra access (database + SSH + deploy pipeline) and belongs to the operator. --- .../api/rest/auth_refresh_internal_test.go | 136 ++++++++++++++++++ backend/api/rest/swagger.yaml | 54 +++++++ 2 files changed, 190 insertions(+) create mode 100644 backend/api/rest/auth_refresh_internal_test.go diff --git a/backend/api/rest/auth_refresh_internal_test.go b/backend/api/rest/auth_refresh_internal_test.go new file mode 100644 index 0000000..301d6d8 --- /dev/null +++ b/backend/api/rest/auth_refresh_internal_test.go @@ -0,0 +1,136 @@ +package rest + +import ( + "encoding/json" + "io" + "net/http" + "net/http/httptest" + "strings" + "testing" + + "github.com/stretchr/testify/require" +) + +// Server-level HTTP smoke tests for the endpoints introduced in PR #8 +// (/api/v1/auth/refresh and /api/v1/auth/logout).
