Mocking IXMLHTTPRequest2? about libhttpclient HOT 3 CLOSED

IXMLHttpRequest2 is an platform API. The goal of this project isn't to test IXMLHTTPRequest2 of course since that better work since its an old platform API.

We're mocking above our platform abstraction layer (which calls platforms APIs on UWP/Xbox/iOS/Android/etc). The mocks are really for something like a game that wants to serve up fake data when in "editor" mode so they don't have to sign in to Xbox Live, etc to populate the UI.

You can see the mock API here: https://github.com/Microsoft/libHttpClient/blob/master/Include/httpClient/mock.h. It works similar to a Fiddler auto-responders in that it does patter matching and a match is found it'll use return data found in the mock you set.

IXMLHTTPRequest2 of course since that better work since its an old platform API

If I pass new lines in my url it silently/happily removes new lines and fetches wrong url (e.g. url without newlines isn't the one I was requesting). Whatever I try to test I get issues with it.

In my case instead of mocking responses I actually implemented in c++ an http server with nodejs-style api (that is, in 3-5 lines of code I can handle simple http requests right in my code) and since server and client are in the same process I can easily tell the server what it should serve me. This way I can make it work overall as close as possible to real http requests. This is off course isn't possible with ixml2 as I need to hook dns resolution.

I thought that you tried to do similar type of mocking.

Also, only by mocking and testing I can ensure that all http backends (curl, msxml, etc) yield exactly the same results in my wrapper api. For example, two redirects followed by timeout, or failed dns resolution: all these should produce identical results regardless of backend. Overall I have very similar goals as libHttpClient :) didn't know this project existed.

Yeah that makes sense. Our primary tests are to ensure that the Xbox Live services respond correctly (via XSAPI) regardless of the http backend we are using.

But if you want to mock on Xbox in the pattern your doing, if you have access to the XDK, you might be able to do https://docs.microsoft.com/en-us/windows/uwp/xbox-live/using-xbox-live/troubleshooting/how-to-set-up-fiddler-for-debugging#for-xbox-one-xdk-based-projects and then instead of using Fiddler, setup a http server. Not sure. Never tried it. Alternatively I know you can use Fiddler auto-responders but its more limited than your own http server code.
