Vue CLI Testing: Unit and E2E Test Implementation for Plugin Development
The Vue CLI repository implements a comprehensive testing strategy combining Jest for unit testing and WebdriverIO for end-to-end testing. With 75 test files across the codebase, it demonstrates best practices for testing Vue.js CLI tools, plugin generators, and configuration workflows, with particular emphasis on TypeScript integration and router functionality. Qodo Tests Hub provides developers with an organized view into Vue CLI's testing patterns, making it easier to understand how the project validates critical functionality like preset selection, plugin installation, and framework integrations. By exploring these real-world test implementations, developers can learn practical approaches to testing Vue CLI plugins and tools while understanding the rationale behind different testing strategies.
