Can httptest be used to test HTTP/2?

Question

I'm wondering if this (httptest) package can be used to test HTTP/2 specific features.
Can anyone point me to some examples maybe?

I'm aware of the tool h2i, but it's an interactive tool.
I'm looking for something which is programmable.

EDIT:
What I'm really looking for is a tool, where for example I can initiate a server push and test it on the client side.
So, using this package, how do I have access to the underlying HTTP/2 stuff it uses by default?

EDIT 2:
Found some examples in the nghttp2 source: https://github.com/tatsuhiro-t/nghttp2/tree/master/integration-tests

EDIT 3: For me it looks like that the package net/http2 isn't meant to be used directly by anyone. I'll experiment with this one.

If you're on go 1.6, support for HTTP/2 to is transparently added to net/http for HTTPS (and, I suppose, consequently to net/http/httptest too). – Democracy

What exactly do you want to do? What are you testing? Like muru said, httptest uses the http package. – Stiegler

This package is built on top of httptest and may interest you. – Pigskin

you are using http, not testing http implements. – Bakki

Answer 1

General testing tip (to avoid frustration)!

Don't use Fiddler to test it, it gets in between your browser and the server and breaks the HTTP2 connection.

No HTTP2 - no push.

Do you know if BurpSuite does the same way? – Multitude

I’ve never heard of it but I’d imagine anything in between would do the same unless it explicitly says it can handle it. I’d imagine maybe someday fiddler would add http/2 debugging functionality (if they haven’t already). Also everything will still work except for the server push and single connection. So just disable it during testing and use the browser’s network tab to verify push is working. – Earley

Thanks for the explanation. – Multitude

Answer 2

https://github.com/summerwind/h2spec is a go program that tests whether a server implementation conforms to RFC 7540. It allows to craft individual HTTP/2 frames such as:

    settings := http2.Setting{http2.SettingInitialWindowSize, 0}
    http2Conn.fr.WriteSettings(settings)

or

    var hp http2.HeadersFrameParam
    hp.StreamID = 1
    hp.EndStream = false
    hp.EndHeaders = true
    hp.BlockFragment = http2Conn.EncodeHeader(hdrs)
    http2Conn.fr.WriteHeaders(hp)
