From 18068d203bed6a074b88b567e7387912b1b870d2 Mon Sep 17 00:00:00 2001 From: Bhumika-1432006 Date: Fri, 16 Oct 2026 20:37:28 +0530 Subject: [PATCH] test(app): smoke tests for named routes, healthz, and set_error_handler (#342) Four cwist_app_* functions from issue #342's uncovered list have no test: cwist_app_post_named, cwist_app_delete_named, cwist_app_enable_healthz, and cwist_app_set_error_handler. This adds tests/test_app_named_routes_and_error_handler.c with one case per function: - post_named: register a POST route with a name and verify cwist_url_for returns the registered path. - delete_named: same for DELETE; confirms :param paths are stored. - enable_healthz: call it and confirm no crash; check cwist_url_for for the /healthz path when a name is registered. - set_error_handler: verify app->error_handler is NULL before the call, set to the supplied function pointer after, and NULL-cleared on a second call with NULL. Confirm NULL app is a safe no-op. No live server is started; the tests only exercise registration and lookup. The test is wired into make test via a new Makefile target. --- Makefile | 5 + .../test_app_named_routes_and_error_handler.c | 129 ++++++++++++++++++ 2 files changed, 134 insertions(+) create mode 100644 tests/test_app_named_routes_and_error_handler.c diff --git a/Makefile b/Makefile index de5bc71d..58bbfb4e 100644 --- a/Makefile +++ b/Makefile @@ -891,6 +891,7 @@ TEST_TARGETS = test_worker_affinity \ test_simd_parser \ test_orm \ test_app_resource_limits \ + test_app_named_routes_and_error_handler \ test_classic_pool_scaling \ test_reactor_wake \ test_reactor_timer \ @@ -1087,6 +1088,10 @@ test_app_resource_limits: $(LIB_NAME) tests/test_app_resource_limits.c src/sys/a $(CC) $(CFLAGS) -o $@ tests/test_app_resource_limits.c $(LIB_NAME) $(LIBS) ./$@ +test_app_named_routes_and_error_handler: $(LIB_NAME) tests/test_app_named_routes_and_error_handler.c + $(CC) $(CFLAGS) -o $@ tests/test_app_named_routes_and_error_handler.c $(LIB_NAME) $(LIBS) + ./$@ + test_classic_pool_scaling: $(LIB_NAME) tests/test_classic_pool_scaling.c $(CC) $(CFLAGS) -o $@ tests/test_classic_pool_scaling.c $(LIB_NAME) $(LIBS) ./$@ burst diff --git a/tests/test_app_named_routes_and_error_handler.c b/tests/test_app_named_routes_and_error_handler.c new file mode 100644 index 00000000..d89b951a --- /dev/null +++ b/tests/test_app_named_routes_and_error_handler.c @@ -0,0 +1,129 @@ +/** + * @file test_app_named_routes_and_error_handler.c + * @brief Smoke tests for uncovered cwist_app_* functions (issue #342). + * + * Covers: + * cwist_app_post_named -- register a named POST route;
