/// tip

Keep in mind that if you return a response directly instead of using the `Response` parameter, FastAPI will return it directly.

So, you will have to make sure your data is of the correct type. E.g. it is compatible with JSON, if you are returning a `JSONResponse`.

And also that you are not sending any data that should have been filtered by a `response_model`.

///

### More info { #more-info }

        assertEquals("username", user.getName());
        assertSame(testEnv, user.getEnvironment());
        assertNull(user.permissions);
    }

    public void test_getName() {
        // Test getName returns the correct name
        assertEquals("testuser", ldapUser.getName());

        // Test with different names
        LdapUser user2 = new LdapUser(testEnv, "anotheruser");
        assertEquals("anotheruser", user2.getName());

Whenever a new request arrives, **FastAPI** will take care of:

* Calling your dependency ("dependable") function with the correct parameters.
* Get the result from your function.
* Assign that result to the parameter in your *path operation function*.

    Server->>Proxy: HTTP Response<br/>with correct HTTPS URLs

    Proxy->>Client: HTTPS Response
```

The **proxy** intercepts the original client request and adds the special *forwarded* headers (`X-Forwarded-*`) before passing the request to the **application server**.

You will see the automatic API docs for the sub-application, including only its own _path operations_, all under the correct sub-path prefix `/subapi`:
