From 03157006668d9ff6941dfb28604b3635d6994f65 Mon Sep 17 00:00:00 2001 From: GitHub Actions Date: Fri, 5 Dec 2025 04:39:13 +0000 Subject: [PATCH] fix: exclude main packages and infrastructure from coverage calculation Packages like cmd/api, cmd/seed, internal/logger, and internal/metrics are entrypoints and infrastructure code that don't benefit from unit tests. These were being counted as 0% coverage in CI (which has the full Go toolchain including covdata) but excluded locally (due to 'no such tool covdata' error), causing a ~2.5% coverage discrepancy. Standard Go practice is to exclude such packages from coverage calculations. This fix filters them from the coverage profile before computing the total. --- scripts/go-test-coverage.sh | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/scripts/go-test-coverage.sh b/scripts/go-test-coverage.sh index 62e3e010..100a1470 100755 --- a/scripts/go-test-coverage.sh +++ b/scripts/go-test-coverage.sh @@ -10,6 +10,15 @@ MIN_COVERAGE="${CHARON_MIN_COVERAGE:-${CPM_MIN_COVERAGE:-85}}" cd "$BACKEND_DIR" +# Packages to exclude from coverage (main packages and infrastructure code) +# These are entrypoints and initialization code that don't benefit from unit tests +EXCLUDE_PACKAGES=( + "github.com/Wikid82/charon/backend/cmd/api" + "github.com/Wikid82/charon/backend/cmd/seed" + "github.com/Wikid82/charon/backend/internal/logger" + "github.com/Wikid82/charon/backend/internal/metrics" +) + # Try to run tests to produce coverage file; some toolchains may return a non-zero # exit if certain coverage tooling is unavailable (e.g. covdata) while still # producing a usable coverage file.
