## Adding Guava Testlib to your build

Guava testlib's Maven group ID is `com.google.guava` and its artifact ID is `guava-testlib`.

To add a dependency on Guava testlib using Maven, use the following:

```xml
<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava-testlib</artifactId>
  <version>33.5.0-jre</version>
  <scope>test</scope>
</dependency>
```

    /**
     * Gets a group entity based on the form.
     *
     * @param form the create form
     * @return optional group entity
     */
    private static OptionalEntity<Group> getEntity(final CreateForm form) {
        switch (form.crudMode) {
        case CrudMode.CREATE:
            return OptionalEntity.of(new Group()).map(entity -> {

 }
}
```

Now you have successfully configured Dex IdP with MinIO.

> NOTE: Dex supports groups with external connectors so you can use `groups` as policy claim instead of `name`.

```
export MINIO_IDENTITY_OPENID_CLAIM_NAME=groups
```

and add relevant policies on MinIO using `mc admin policy create myminio/ <group_name> group-access.json`
