Affected Tests in CI

codegraph affected traces import dependencies transitively to find which test files are affected by a set of changed source files — so CI can run only the relevant tests.

codegraph affected src/utils.ts src/api.ts          # pass files as arguments
git diff --name-only | codegraph affected --stdin    # pipe from git diff
codegraph affected src/auth.ts --filter "e2e/*"      # custom test-file pattern

Options

Option	Description	Default
--stdin	Read the file list from stdin	false
-d, --depth <n>	Max dependency traversal depth	5
-f, --filter <glob>	Custom glob to identify test files	auto-detect
-j, --json	Output as JSON	false
-q, --quiet	Output file paths only	false

CI / hook example

#!/usr/bin/env bash
AFFECTED=$(git diff --name-only HEAD | codegraph affected --stdin --quiet)
if [ -n "$AFFECTED" ]; then
  npx vitest run $AFFECTED
