Testing Conventions & Usage

Test Conventions​

  • Test files are named *.spec.ts or *.spec.tsx and colocated with source files
  • Use descriptive test names that explain what is being tested
  • Follow the Arrange-Act-Assert pattern
  • Mock external dependencies to keep tests isolated and fast
  • Use React Testing Library's screen queries for component tests
  • Avoid testing implementation details; focus on user-facing behavior

Running Tests​

# Run all tests
nx run-many -t test

# Run tests for a specific project
nx test my-project

# Run tests in watch mode
nx test my-project --watch

# Run tests with coverage
nx test my-project --coverage
