Every application should be well tested. Actix Web provides tools to perform integration tests against your applications and unit test tools for custom extractors and middleware.
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 handlers or extractors with it. Also see
Integration Testing For Applications
There are 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::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
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 Testing
Unit Testing Extractors
Unit testing has pretty limited value for applications, but can be useful when developing extractors, middleware, and responders. Given that, calling directly into handler functions which are defined stand-alone, without using routing macros (like
#[get("/")]) is possible if you want to make assertions on custom
