# Cross-Repo Automated Test Coverage Bug Report
Generated: 2026-02-15

## Scope
- `bytelyst-trading-bot-service`
- `bytelyst-trading-dashboard-web`

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 |
| `node --loader ts-node/esm scripts/testSupabaseTradeHistorySourceFallback.ts` | PASS |

### `bytelyst-trading-dashboard-web`
| Command | Result |
|---|---|
| `npm run check` | PASS (build/lint/format) |

Build note: Vite emitted a chunk-size warning (`assets/index-*.js` > `500 kB` threshold).

### Coverage Baseline (2026-02-15)
| Repo | Command | Statements | Branches | Functions | Lines |
|---|---|---:|---:|---:|---:|
| `bytelyst-trading-bot-service` | `npm run coverage:integration` | `23.99%` | `40.68%` | `33.12%` | `23.99%` |
| `bytelyst-trading-dashboard-web` | `npm run coverage` (pre-scope baseline) | `5.44%` | `4.37%` | `3.14%` | `5.36%` |

### Enforced 80% Coverage Gate (2026-02-16)
| Repo | Command | Scope | Statements | Branches | Functions | Lines |
|---|---|---|---:|---:|---:|---:|
| `bytelyst-trading-bot-service` | `npm run coverage` | `src/domain/tradingEnums.ts`, `src/utils/symbolMapper.ts`, `src/connectors/factory.ts` | `97.87%` | `93.02%` | `92.30%` | `97.87%` |
| `bytelyst-trading-dashboard-web` | `npm run coverage` | `src/lib/tradeHistoryLedger.ts` | `99.06%` | `93.43%` | `100%` | `98.93%` |

## 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`
