Dart make custom HttpRequest

Question

I want to make a custom HttpRequest to unit test my api code. The code I want to test:

if (WebSocketTransformer.isUpgradeRequest(request)) {
      await webSocketRequest.handleRequest(
          request: request, streamController: streamController);
}

The method WebSocketTransformer checks the method and the headers content. Therefore I have to hand in a HttpRequest .

  HttpRequest mockWSRequest; 
  mockWSrequest.headers.set('connection', 'upgrade');

But how can I set the HttpRequest 's method?

Answer 1

If you're talking about dart:io 's HttpRequest class, that class is abstract and cannot be directly instantiated. If you want to create a mock, then you would have your mock implement the HttpRequest interface and add an implementation for its method getter to return 'GET' or 'POST' as desired.
