Conformance testing tool for HTTP/2 implementation.

      --dryrun                  Display only the title of test cases
      --help                    Display this help and exit
  -h, --host string             Target host (default "127.0.0.1")
  -k, --insecure                Don't verify server's certificate
  -j, --junit-report string     Path for JUnit test report
      --max-header-length int   Maximum length of HTTP header (default 4000)
  -P, --path string             Target path (default "/")
  -p, --port int                Target port
  -S, --strict                  Run all test cases including strict test cases
  -o, --timeout int             Time seconds to test timeout (default 2)
  -t, --tls                     Connect over TLS
  -v, --verbose                 Output verbose log

Running a specific test case

You can choose a test case to run by specifying the Spec ID as the command argument. For example, if you want to run test cases for HTTP/2, run h2spec as following:

$ h2spec http2

If you add a section number after the Spec ID, test cases related to a specific section will be run. For example, if you want to run test cases related to 6.3 of HTTP/2, run h2spec as following:

$ h2spec http2/6.3

If you add a test number after the section number, you can run the specific test case individually. For example, to run only the first test case related to 6.3 of HTTP/2 6.3, run h2spec as following:

$ h2spec http2/6.3/1

The Spec ID can be specified multiple times.

$ h2spec http2/6.3 generic

Currently supported Spec IDs are as follows. generic is the original spec of h2spec, includes generic test cases for HTTP/2 servers.

Dryrun Mode

To display the list of test cases to be run, use Dryrun Mode as follows:

$ h2spec --dryrun

Strict Mode

When Strict Mode is enabled, h2spec will run the test cases related to the contents requested with the SHOULD notation in each specification. It is useful for more rigorous verification of HTTP/2 implementation.

$ h2spec --strict
