Day.js Testing – Jest Unit Testing Implementation
The dayjs library's testing suite demonstrates a comprehensive unit testing approach using Jest as the primary testing framework. The test suite includes 92 test cases covering core utilities, plugin functionality, and locale-specific features, with particular attention to datetime manipulation, formatting operations, and TypeScript declarations verification. Qodo Tests Hub provides developers with detailed insights into dayjs's testing patterns, making it easier to understand how to effectively test datetime libraries. Through the platform, developers can explore real-world examples of Jest unit tests, examine timezone handling implementations, and learn best practices for testing internationalization features. This practical knowledge helps teams implement more robust testing strategies in their own projects.
