From c33e5421b3e1a41508cfd737712f1a7af551777e Mon Sep 17 00:00:00 2001 From: Tym Rabchuk Date: Sun, 5 Apr 2026 19:06:14 -0400 Subject: [PATCH] =?UTF-8?q?Add=20hook=20smoke=20tests=20=E2=80=94=2020=20t?= =?UTF-8?q?ests=20across=20all=2010=20registered=20hooks?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tests each hook's I/O contract: valid JSON output, correct exit codes, empty input handling, and key behaviors (safety-check blocks rm -rf /, lang-review skips non-code files, stop-gate approves clean trees). Added as a separate CI job (hook-smoke-tests) alongside build-and-test and validate-counts. --- .github/workflows/ci.yml | 8 ++ hooks/hooks_test.sh | 160 +++++++++++++++++++++++++++++++++++++++ 2 files changed, 168 insertions(+) create mode 100644 hooks/hooks_test.sh diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index b735087..58c03d2 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -39,6 +39,14 @@ jobs: exit 1 fi + hook-smoke-tests: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + + - name: Run hook smoke tests + run: bash hooks/hooks_test.sh + validate-counts: runs-on: ubuntu-latest steps: diff --git a/hooks/hooks_test.sh b/hooks/hooks_test.sh new file mode 100644 index 0000000..d65d068 --- /dev/null +++ b/hooks/hooks_test.sh @@ -0,0 +1,160 @@ +#!/bin/bash +# Smoke tests for all 10 registered hooks. +# Validates: (1) script exits 0, (2) output is valid JSON when expected, +# (3) correct contract schema for each lifecycle event. +# +# Run from repo root: bash hooks/hooks_test.sh + +set -uo pipefail + +HOOK_DIR="$(cd "$(dirname "$0")" && pwd)" +PASS=0 +FAIL=0 +ERRORS="" + +pass() { PASS=$((PASS + 1)); echo " PASS: $1"; } +fail() { FAIL=$((FAIL + 1)); ERRORS="$ERRORS\n FAIL: $1"; echo " FAIL: $1"; } + +# Helper: run a hook with given input, check exit code and optionally validate JSON +run_hook() { + local script="$1" input="$2" label="$3" expect_json="${4:-false}" + + OUTPUT=$(echo "$input" | bash "$HOOK_DIR/$script" 2>/dev/null) || true + EXIT=$?
