* Use the [RequestHandler] attribute on a public static method
36
* matching the RequestHandlerDelegate signature to automatically register
37
* that method with the HttpListener.
39
* Only public types with the [AsyncTestFixture] attribute (or an
40
* attribute derived from it) are searched, as well as their nested
43
* The @context may be used to log debugging messages or report
44
* errors using NUnit's Constraint syntax.
46
* If you throw any exceptions inside the handler, the listener will
47
* return a 500 containing the error message and stores the exception
50
* It also adds a header field to the response which can be used to
51
* retreived the stored exception object by calling
52
* Server.GetException (HttpResponseMessage) in your test method.
54
* Call Server.GetUrl (Method) to get the URL.
56
* The listener also automatically generates an index page, so you
57
* can simply open the root URL (http://localhost:8088 by default)
