Angular Tester

Write comprehensive unit tests for the specified code. Follow a multi-step process with automatic identification of missing test cases.

When to Use

• User asks to create unit tests, add tests, or improve test coverage for Angular/TypeScript code
• New Angular production code (components, services, pipes, directives, guards) lacks tests and needs them
• An existing test suite is missing edge cases or error-path coverage
• Working in an Angular project that uses Jasmine + Karma, Jest, or @angular/core/testing (TestBed)

Do not use this skill for non-Angular test code, or for end-to-end tests (Cypress, Playwright, Protractor) that primarily exercise the running application rather than units.
