The goal is to create a reference with real-world test examples, including: - Forms with onSubmit handlers - Input validation and value assertions - Button clicks and user interaction - Using jest.fn() to spy on function calls - Fetching data from APIs with loading and error states - Simple and complex component behavior Each folder in components/ includes a demo component along with its test file. --- 👨‍💻 Built by Milad Joodi 📂 Personal reference and learning project --- ✅ Useful Testing Tools and Matchers 📦 Core Tools - jest.fn() Creates a mock function. Useful for tracking calls and arguments. - render(component) Renders a React component into the testing DOM. - screen Access rendered elements using queries like getByText , getByRole , etc. - userEvent Simulates user interactions (click, type, etc.) - waitFor(callback) Waits for an async condition to be true. Handy for async rendering. - beforeEach() / afterEach() Setup or cleanup logic before/after each test. --- 🧪 Matchers with expect() - expect(value) Base function to assert values or behaviors. - .toBe(value) Checks strict equality. - .toEqual(object) Deep comparison for objects or arrays. - .toBeTruthy() / .toBeFalsy() Checks if a value is truthy or falsy. - .toContain(item) Checks if string/array contains a value. - .toHaveTextContent(text) Asserts a DO","default_branch":null,"files":null,"tree":[],"storefront":"/r/MiladJoodi","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/MiladJoodi/Nextjs-Testing-Examples/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
