Testing Ionic React
This document provides an overview of how to test an application built with @ionic/react. It covers the basics of testing with React, as well as the specific tools and libraries used in @ionic/react.
Introduction
Testing is an important part of the development process, and it helps to ensure that an application is working as intended. In @ionic/react, testing is done using a combination of tools and libraries, including Vitest, Jest, React Testing Library, Playwright or Cypress.
Types of Tests
There are two types of tests that can be written:
Unit Tests: Unit tests are used to test individual functions and components in isolation. They can be written using tools such as Jest and React Testing Library or Vitest.
Integration Tests: Integration tests are used to test how different components work together. They can be written using tools such as Cypress or Playwright.
Tools and Libraries
Unit Testing
Jest: Jest is a popular testing framework for JavaScript applications. It is included with react-scripts and is used to run unit tests.
Vitest: Vitest is a modern testing framework powered by Vite. It is compatible with Jest and is used to run unit tests.
React Testing Library: React Testing Library is a set of utilities that make it easy to test React components. It's used to interact with components and test their behavior.
Integration Testing
Cypress: Cypress is a modern testing tool that's used to run end-to-end tests. It allows developers to test the entire application, including the user interface, in a simulated environment.
Playwright: Playwright is a browser automation library that's used to run end-to-end tests. It allows developers to test the entire application, including the user interface, in a simulated environment.
