| Variant name matching is case-insensitive and partial. For example, `--variant 13` will match `nextjs-pages-dir (next@13)` if a matching variant is present in the test app's `package.json`. |

I have been running a lot of Next.js tests and needed to run specific variants against my changes, so I made these changes to our test runner script and thought to share it with everyone.
Closes #18459 (added automatically)
