+### `--testEnvironmentOptions=<json string>`
+
+A JSON string with options that will be passed to the `testEnvironment`. The relevant options depend on the environment.
+
 ### `--testNamePattern=<regex>`
 
 Alias: `-t`. Run only tests with a name that matches the regex. For example, suppose you want to run only tests related to authorization which will have names like `"GET /api/posts with auth"`, then you can use `jest -t=auth`.
