Category

Test importing from wrong location / Dead export in production module

Summary

Multiple production source files export test-helper objects that are exclusively consumed by test files. This is a recurring pattern that has regressed across several modules:

File	Exported Symbol	Prior Issue
src/container-lifecycle.ts	containerLifecycleTestHelpers	regression of #3369
src/copilot-api-resolver.ts	copilotApiResolverTestHelpers	—
src/host-env.ts	hostEnvTestHelpers	—
src/logs/log-discovery.ts	logDiscoveryTestHelpers	regression of #3525

Evidence

src/container-lifecycle.ts:469:export const containerLifecycleTestHelpers = { isAgentExternallyKilled, resetAgentExternallyKilled };

Used only in: src/docker-manager-lifecycle.test.ts

src/copilot-api-resolver.ts:88:export const copilotApiResolverTestHelpers = { ... };

Used only in: src/copilot-api-resolver.test.ts, src/cli.test.ts

src/host-env.ts:52:export const hostEnvTestHelpers = { subnetsOverlap };

Used only in: src/docker-manager-utils.test.ts

src/logs/log-discovery.ts:168:export const logDiscoveryTestHelpers = { isContainerRunning };

Used only in: src/logs/log-discovery.test.ts

Recommended Fix

For each symbol:

1. Remove the export const *TestHelpers = ... object from the production file
2. Either move the helper into a co-located *.test-utils.ts file, or expose the underlying function directly from a test-utils module
3. Update test imports accordingly

Impact

• Dead code risk: Medium — test-only state-mutation helpers on production module surfaces
• Maintenance burden: Medium — four separate modules affected; pattern likely to keep regressing without a lint rule
