@njong392/qa-duplicate-check

Config-driven duplicate detection for QA codebases.

It supports:

• Function duplicate detection (similarity-based)
• Variable duplicate detection (exact string-content match)
• Commit-time enforcement (strict block or prompt override)

Install

npm i -D @njong392/qa-duplicate-check

Config

Create qa-duplicate-check.config.js in your project root:

module.exports = {
  functionSimilarityThreshold: 0.92,
  commitMode: 'strict', // 'strict' | 'prompt'
  rules: [
    {
      name: 'QA Actions',
      path: 'cypress/e2e/actions',
      kind: 'functions', // 'functions' | 'variables'
      include: ['.js'],
      crossFile: true,
    },
    {
      name: 'QA Pages',
      path: 'cypress/e2e/pages',
      kind: 'variables',
      include: ['.js'],
      crossFile: true,
    },
  ],
};
