Only 21 of 86 test_*.c group functions called their own nested UNITY_BEGIN()/UNITY_END(). Each nested call reset Unity's global NumberOfTests/TestFailures counters, so controller_test.c's final `return UNITY_END();` -- the value meson test actually gates on -- only ever reflected whichever small window of tests ran since the LAST nested reset, silently discarding pass/fail evidence for everything before it (measured: 16 of 972 total tests in one run). The same nested-BEGIN calls also caused PASS/FAIL banners to show the wrong source file for tests in files that don't reset it themselves (Unity.TestFile just carries over from whichever group last called UNITY_BEGIN()). Fix: replace every nested UNITY_BEGIN() with UnitySetTestFile(__FILE__) (sets file attribution only, no counter reset) and drop the matching UNITY_END(); add the same UnitySetTestFile(__FILE__) as the first statement to the other group functions that had neither. The 2 genuinely standalone binaries (test_job_array_sched_push.c, test_job_array_apiserver_push.c -- each has its own int main(), not registered via controller_test.c's TEST() macro) are untouched. Verified: single consolidated summary now reads "972 Tests 0 Failures 0 Ignored OK", exactly matching the ground-truth RUN_TEST call-site count across all 83 registered group files (976 total minus 4 belonging to the 2 standalone binaries). Every PASS/FAIL banner now names its own true source file. Full xce-build.sh all regression pass clean (Ok: 9, Fail: 0). No production code touched -- test-harness plumbing only.

/* test_ctrl_metrics.c — P3-7: Metrics infrastructure unit tests
|
|
*
|
|
* TDD: these tests are written FIRST to drive the implementation.
|
|
* They verify:
|
|
* - ctrl_metrics_init() zeroes all 7 counters/gauges
|
|
* - CTRL_METRIC_INC increments atomically
|
|
* - CTRL_METRIC_SET writes and overwrites a gauge
|
|
* - The descriptor table has exactly 7 entries + NULL sentinel
|
|
* - ctrl_transient_jobs_stuck counter accumulates correctly
