Test Case

Starting test '4) Http\Adapter\Artax\Test\ClientTest::testSendRequest with data set #11 ('TRACE', 'http://127.0.0.1:10000/server.php', array('close', 'PHP HTTP Adapter', '0', 'utf-8', 'en'), 'param1=foo&param2%5B0%5D=bar&...5D=baz').

Actual Behavior

Failed asserting that an array has the key 'HTTP_CONTENT_LENGTH'.

Expected Behavior

The test shouldn't assert what it does. https://tools.ietf.org/html/rfc7231#section-4.3.8 says:

A client MUST NOT send a message body in a TRACE request.

Possible Solutions

All current clients fail to obey the RFC here and send a request body. artax-adapter does it better and just strips the body. Whether it should error out or silently strip is out of scope for this issue.

This was actually a mistake with Artax removing the body for HEAD and OPTIONS requests, which is fixed now. But the same issue persists with TRACE requests, which MUST NOT have a body.
