Good afternoon -

I am attempting to test b1 XDR Test 7, which is described as follows:
"Verifies the ability of the sending system to reject a mutual TLS connection where the certificate provided by the ETT is invalid." I was expecting this to mean that when I call the ETT endpoint (https://ett.healthit.gov:11084/xdstools/sim/edge-ttp__7/rep/xdrpr), the ETT would present an invalid certificate, causing the TLS handshake to fail.

However, when calling that endpoint both from my application, via Postman, and through curling, the ETT is responding with a valid certificate, so our handshake is succeeding and we are getting a successful SOAP response back, resulting in the test failing. 

Is the endpoint supposed to be presenting an invalid cert here? How are testing systems supposed to pass this test?

For example: 

* Host ett.healthit.gov:11084 was resolved.

* IPv6: (none)

* IPv4: 34.235.25.130

*   Trying 34.235.25.130:11084...

* Connected to ett.healthit.gov (34.235.25.130) port 11084

* ALPN: curl offers h2,http/1.1

*  CAfile: /etc/ssl/cert.pem

*  CApath: none

Similarly, going to that URL in a browser gets a 400, but the certificate for *.healthit.gov is valid.
