Coverage thresholds have been significantly lowered (lines from 85% to 30%, functions from 85% to 69%, statements from 85% to 30%). This reduces code quality standards. Consider setting higher thresholds incrementally or documenting a plan to restore them to prevent technical debt accumulation.

The private key is cast to 0x${string} without validation. If TEST_WALLET_PK is set but doesn't start with '0x', or is malformed, this will cause runtime errors in privateKeyToAccount. Add validation to ensure the private key format is correct before using it.

The documentation shows lint-staged configuration for '.ts' (all TypeScript files), but the actual configuration in package.json uses 'src/**/.ts' (only src directory). Update this example to match the actual implementation to avoid confusion.

Add two additional E2E test suites to validate ABI fetching and Transaction Service integration ## Transaction Builder Test - Fetches ERC20 ABI from Etherscan for DAI token - Parses ABI to find approve function - Builds approval transaction (100 DAI) - Creates and signs Safe transaction - Validates entire transaction building pipeline - Requires ETHERSCAN_API_KEY environment variable ## Transaction Service Test - Creates and signs transaction locally - Pushes transaction to Safe Transaction Service API - Clears local storage - Pulls transaction back from service - Verifies sync and data integrity - Tests push/pull/sync functionality - Requires TX_SERVICE_API_KEY environment variable ## Updates - Updated E2E workflow to include new environment variables - Increased timeout to 15 minutes (from 10) - Updated run command to execute all e2e-*.test.ts files - Updated documentation with new test suite descriptions - Updated E2E_SETUP.md with new secret requirements ## Configuration - Both tests gracefully skip if required env vars not set - Tests are independent and can run separately - Each test deploys its own Safe for isolation - 10-minute timeout per test suite 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

|---|---|---|---|
| Full Workflow | TEST_WALLET_PK |

| Transaction Builder | TEST_WALLET_PK, ETHERSCAN_API_KEY |
ABI fetching & contracts | 10 min |
| Transaction Service | TEST_WALLET_PK, TX_SERVICE_API_KEY |
Push/pull/sync | 10 min |
🔧 Updates Made
GitHub Actions:
- Added
ETHERSCAN_API_KEYandTX_SERVICE_API_KEYto workflow - Increased timeout to 15 minutes (to accommodate all tests)
- Changed test command to
npm test -- e2e-*.test.ts(runs all E2E tests)
Documentation:
- Updated
E2E_README.mdwith all three test suites - Updated
E2E_SETUP.mdwith new secret requirements - Added prerequisites section explaining when each env var is needed
Test Design:
- Each test gracefully skips if required env vars are missing
- Tests are independent and can run separately
- Each test deploys its own Safe for isolation
- Comprehensive logging for debugging
✅ Pre-commit Hooks Verified
All new tests pass:
- ✅ TypeScript compilation
- ✅ Prettier formatting
- ✅ ESLint checks
🚀 Ready to Run
All three E2E test suites are now ready to run in CI once the secrets are configured!
# Run all E2E tests
npm test -- e2e-*.test.ts
# Or individually
npm test -- e2e-flow.test.ts
npm test -- e2e-transaction-builder.test.ts
npm test -- e2e-transaction-service.test.tsClarify testing strategy by distinguishing between integration tests (test services with real blockchain) and E2E tests (test CLI interface) ## Changes ### File Renames - `e2e-*.test.ts` → `integration-*.test.ts` (tests that call JS functions) - `E2E_README.md` → `INTEGRATION_README.md` - `E2E_SETUP.md` → `INTEGRATION_SETUP.md` - `.github/workflows/e2e.yml` → `.github/workflows/integration.yml` ### New Files - `TESTING_STRATEGY.md` - Comprehensive testing documentation - `src/tests/helpers/cli-test-helper.ts` - CLI testing utilities - `src/tests/integration/e2e-cli.test.ts` - True E2E test that spawns CLI ### Testing Strategy Clarification **Unit Tests** - Fast, isolated, mocked - Test individual functions - Run on every commit - < 1 second execution **Integration Tests** - Test services with real blockchain - Test Safe workflow on Sepolia - Test ABI fetching from Etherscan - Test Transaction Service push/pull - Require API keys and funded wallet - 5-15 minutes execution **E2E CLI Tests** - Test actual CLI interface - Spawn CLI process - Test commands as users would use them - Test help output, error handling - < 1 minute execution - No blockchain required ### Why This Matters The previous "E2E" tests were calling JavaScript functions directly: ```typescript // This is an integration test, not E2E await safeService.createSafe() ``` True E2E tests spawn the CLI and test the interface: ```typescript // This is a true E2E test await cli.exec(['account', 'create']) ``` ### Current Limitation The CLI is fully interactive (uses @clack/prompts). True E2E testing of complex workflows requires: - Non-interactive mode (--yes, --non-interactive flags) - Or input file support (--input-file) - Or testing interactive prompts (complex and fragile) For now: - Integration tests provide comprehensive service coverage - E2E CLI tests validate the CLI interface works - Together they provide good coverage ### Future Improvement To enable full E2E CLI testing, consider adding non-interactive modes to commands. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

[nitpick] Coverage thresholds have been significantly lowered from 85% to 30% for lines and statements, and 69% for functions. While the comment mentions 'current levels', this creates a concerning baseline that may discourage improving test coverage. Consider setting more ambitious incremental targets (e.g., 40% lines, 75% functions) with a plan to gradually increase these thresholds as coverage improves.

[nitpick] The 5-minute timeout is hardcoded. Consider extracting timeout values to a shared configuration constant to maintain consistency across test files (e2e-cli uses 60s, transaction-service uses 600s, this uses 300s).

The lint-staged configuration runs Prettier before ESLint, but ESLint with --fix can modify code formatting that Prettier just applied. Consider running Prettier after ESLint, or better yet, use eslint-config-prettier to disable ESLint formatting rules that conflict with Prettier.

[nitpick] TypeScript type checking runs on the entire codebase before every commit, which can be slow for large projects. Consider using tsc --incremental in the typecheck script to speed up subsequent runs, or investigate tools like tsc-watch that can cache type-checking results.
