Regex Testing Workflow
Regex quality is defined less by shortness and more by robust test sets and edge-case coverage.
Working model
- Positive set: strings that must match
- Negative set: strings that must not match
- Edge cases: whitespace, unicode, and line boundary scenarios
For live testing, use Regex Debugger.
