# Zerg Testing

## Rules
- Always use Make targets. Never run pytest/bun/playwright directly.

## Core Commands
```bash
make test                # unit tests
make test-e2e-core       # core E2E (must pass 100%)
make test-e2e            # full E2E (retries ok)
make test-full           # unit + full E2E + visual checks
make test-e2e-single TEST=tests/<spec>.ts
make test-e2e-errors     # show last E2E errors
make test-e2e-verbose    # full output for debugging
```

## Debugging Flow
1) `make test-e2e-errors`
2) `make test-e2e-single TEST=tests/<spec>.ts`
3) `make test-e2e-verbose`

## Flake Policy
- Keep core E2E at retries=0. If a CI failure passes on rerun with no code
  diff, quarantine or move that test out of the blocking lane the same day and
  leave a tracking issue; do not normalize red-but-ignored CI.
