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.

Editorial Note
