# Command Controller

The "tea" extension comes with a CommandController that can be used for the
automatic creation of test data. It also serves to illustrate how data can be
created in the database using a command controller.

You must set a page id as argument. Therefore it's necessary to create an
sysfolder before.

You can add option `-d` to delete already existing data.

```bash
vendor/bin/typo3 tea:create-test-data 3
```
