+npm run test      # Test with the locally installed Node.js version

+#### Sequential

 ```sh
-npm run test          # Test with the installed Node.js version
-npm run test:options  # Test with the installed Node.js version using CLI options

+npm run test:sequential      # Test with the locally installed Node.js version
+npm run test:bun:sequential  # Test with the locally installed Bun version

+#### Parallel

+npm run test:parallel      # Test with the locally installed Node.js version
+npm run test:bun:parallel  # Test with the locally installed Bun version

 ### Coverage
 
 Methods that vary according to **Node.js** version, platform or OS aren't tested against the coverage rate.
