This report documents automated test execution results, coverage observations, discovered defects, and the coverage instrumentation baseline added on 2026-02-15.

Automated Execution Summary

bytelyst-trading-bot-service

Command	Result
npm run check	PASS
node --loader ts-node/esm scripts/run_all_tests.ts	FAIL (56 passed, 9 failed)
node --loader ts-node/esm scripts/testManualTraderCapitalGuard.ts	PASS

Coverage Snapshot

bytelyst-trading-bot-service

• 65 TypeScript test scripts under tests/
• 37 TypeScript source files under src/
• Coverage is integration-heavy (Supabase, Alpaca, localhost HTTP) and now has both:
  • broad integration snapshot via npm run coverage:integration
  • enforced 80% gate for selected critical modules via npm run coverage
• Existing check pipeline validates schema/security/lifecycle/order-sync contracts, but does not run the full tests/ folder.

bytelyst-trading-dashboard-web

• 32 source files under src/
• 1 unit test file baseline under src/lib
• Current automation now includes vitest coverage with an 80% gate for selected critical module scope, but UI/e2e behavior remains largely untested.

Bugs Found by Automated Tests

Failing tests from scripts/run_all_tests.ts

• check_alerts.ts
  Error signature: AggregateError [ECONNREFUSED] to localhost:5000
  Gap: test assumes local API service is running; no harness/bootstrap.

• debug_db_logging.ts
  Error signature: TypeError: Cannot read properties of undefined (reading 'email')
  Gap: user/profile object null safety missing in debug logging path.

• final_e2e_param_verification.ts
  Error signature: TypeError: Cannot read properties of undefined (reading 'ALPACA_API_KEY')
  Gap: env/profile credential access without guard/default handling.

• simple_check.ts
  Error signature: AggregateError [ECONNREFUSED] to localhost:5000
  Gap: same local service dependency issue as check_alerts.ts.

• test_alpaca_exhaustive.ts
  Error signature: TypeError: symbols.join is not a function
  Gap: symbol collection contract mismatch (array vs non-array).

• test_fuzzy_match.ts
  Error signature: TypeError: this.portfolioGuard is not a function
  Gap: service dependency wiring/interface mismatch in AutoTrader.

• test_safe.ts
  Error signature: TypeError: symbols.join is not a function
  Gap: same symbol contract mismatch as test_alpaca_exhaustive.ts.

• test_slash.ts
  Error signature: TypeError: symbols.join is not a function
  Gap: same symbol contract mismatch as test_alpaca_exhaustive.ts.

• verify_realtime.ts
  Error signature: TypeError: supabaseService.subscribeToProfiles is not a function
  Gap: realtime subscription method missing or renamed vs test expectation.

Additional Anomalies Observed During Test Sweep

These surfaced in test output and should be triaged, even when the wrapper test status was PASSED.

• check_alpaca_pos.ts: TypeError: exchange.getPositions is not a function
• test_query.ts: Code: 22P02 (invalid UUID input path)
• test_strategy_logic.ts: TypeError: this.executionManager.getPendingOrders is not a function
• check_user_schema.ts and verify_profiles_e2e.ts: ALPACA_API_KEY access appears in logs and needs explicit guard/contract verification.

High-Impact Coverage Gaps

• No deterministic test harness for external dependencies (Supabase, Alpaca, local API service).
• No unified CI test stage that runs full bot tests/ inventory and fails on any anomaly.
• Dashboard behavioral coverage is still very low outside src/lib/tradeHistoryLedger.ts and needs tab/component-level tests.
• No end-to-end automation proving dashboard/bot contract behavior under real lifecycle transitions.

Artifacts

• Bot full suite log: bytelyst-trading-bot-service/.tmp_run_all_tests.log
• Bot check log: bytelyst-trading-bot-service/.tmp_npm_check.log
• Dashboard check log: bytelyst-trading-dashboard-web/.tmp_npm_check.log
