## Tests
To run tests:
- :test_tube: Run `lerna run test:unit` for unit tests.
- :test_tube: Run `lerna run test:e2e` for end-to-end tests.
- :test_tube: Run `lerna run test:spec` for spec tests.

- :test_tube: Run `yarn check-types` to check TypeScript types.
- :test_tube: Run `yarn lint` to run the linter (ESLint).
Contributing to tests:
- Test must not depend on external live resources, such that running tests for a commit must be deterministic:
- Do not pull data from external APIs like execution JSON RPC (instead run a local node).
- Do not pull unpinned versions from dockerhub (use deterministic tag) or Github (checkout commit not branch).
- Carefully design tests that depend on timing sensitive events like p2p network e2e tests. Consider that Github runners are significantly less powerful than your development environment.
### Debugging Spec Tests
- To fix errors always focus on passing all minimal tests first without running mainnet tests.
