Lembre-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e então instalar a dependência, por exemplo:

```console
$ pip install python-multipart
```

## Importe `Form`

        testData.add(createRelatedContent("python", "Python Programming", ""));
        mockBhv.setTestData(testData);

        int count = relatedContentHelper.load();
        assertEquals(1, count); // One virtual host key (empty)

        String[] results = relatedContentHelper.getRelatedContents("java");
        assertEquals(1, results.length);
        assertEquals("Java Programming", results[0]);

There are utilities to configure it easily that you can use directly in your **FastAPI** application (provided by Starlette).

## Install dependencies { #install-dependencies }
