Testing
Every application should be well tested. Actix-web provides tools to perform unit and integration tests.
Unit Tests
For unit testing, actix-web provides a request builder type.
TestRequest implements a builder-like pattern. You can generate a
HttpRequest instance with to_http_request() and call your handler with it.

Integration tests
There a few methods for testing your application. Actix-web can be used to run the application with specific handlers in a real http server.
TestRequest::get(), TestRequest::post() and other
methods can be used to send requests to the test server.
To create a Service for testing, use the test::init_service method which accepts a
regular App builder.
Check the api documentation for more information.

If you need more complex application configuration testing should be very similar to creating
the normal application. For example, you may need to initialize application state. Create an
App with a data method and attach state just like you would from a normal application.

Stream response tests
If you need to test stream it would be enough to call take_body() and convert a resulting ResponseBody
to future and execute it.
For example of testing Server Sent Events.
