# HttpOverrides class abstract

This class facilitates overriding HttpClient with a mock implementation. It should be extended by another class in client code with overrides that construct a mock implementation. The implementation in this base class defaults to the actual HttpClient implementation. For example:

    // An implementation of the HttpClient interface
    class MyHttpClient implements HttpClient {
      MyHttpClient(SecurityContext? c);

      @override
      noSuchMethod(Invocation invocation) {
        // your implementation here
      }
    }

    void main() {
      HttpOverrides.runZoned(() {
        // Operations will use MyHttpClient instead of the real HttpClient
        // implementation whenever HttpClient is used.
      }, createHttpClient: (SecurityContext? c) => MyHttpClient(c));
    }
