With HTTP2_BROWSER environment variable, I can run the test against nghttp
client. Thank you.

- invalid-level-goaway-test

I fixed this sometime ago in nghttp2

- *-when-closed-test

I'm thinking they are really necessary. The spec says it is RST_STREAM
situation, but responding each frame
with RST_STREAM is just wasting the processing and memory (e.g., many DATA
frames comes from the remote and responding each with
RST_STREAM). So "smart" client may remember when RST_STREAM is issued to
certain stream, but what gains if we do that using extra
memory. As a good compromise, I think it is best to ignore these frames.

- *-when-idle-test

I thought that these are the same categories of *-when-closed-test. So I
did not implement the check for this idle test.
It is not generally possible to detect that which stream ID is currently
idle without remembering all stream ID used so far,
especially those which are smaller than the last used/received stream ID.
But it is possible to detect idle stream which has larger stream ID than
the currently used. The current test case uses
stream ID 2, which is just the case. I have pending local commits to detect
this situation to pass the tests.


- push-promise-when-reserved-remote-test
With the latest nghttp2 and http2-test, this test passes.

- priority-when-reserved-remote
What does WRONG TEST mean?


I don't know why but the following tests fail on my PC:

- huge-index-test
  Error: done() invoked with non-Error: Not appropriate error code:
COMPRESSION_ERROR

- invalid-data-1-test
  Error: timeout of 10000ms exceeded

- invalid-data-2-test
  Error: timeout of 10000ms exceeded

- oversized-ping-test
  Error: done() invoked with non-Error: Not appropriate error code:
FRAME_SIZE_ERROR
