Automated Testing
All regex patterns in this repository are rigorously tested to ensure accuracy and reliability. Each pattern includes a comprehensive test suite that validates against the exact test cases shown in the table for that pattern. The tests are currently implemented in TypeScript using Bun's test framework. You can view the complete test suite in our GitHub repository, where every pattern is verified against both valid and invalid inputs to ensure consistent behavior.
