+### Running one test
+
+To run only a single test, add `"only": true` to the `options.json` inside any test fixture folder (you may have to create the file if it doesn't exist).
+For example, let's say we want to only run the test for the [`test/fixtures/comments/basic/shebang-import`](https://github.com/babel/babylon/tree/7.0/test/fixtures/comments/basic/shebang-import) fixture.
