Testing Strategy

Guardrails

• Test files live in __tests__/ directories
• Coverage thresholds enforced: 80% for statements, branches, functions, lines
• No snapshot tests
• Full suite runs on PRs (unit + integration)

import type { Config } from 'jest';
const config: Config = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  roots: ['<rootDir>/apps', '<rootDir>/packages'],
  collectCoverage: true,
  coverageDirectory: 'coverage',
  coverageThreshold: { global: { branches: 80, functions: 80, lines: 80, statements: 80 } }
};
export default config;

LLM Notes

• Prefer unit tests for logic. Use integration tests when hitting real services/emulators.
• Include tests and adjust thresholds only via ADR if you must relax them.
