As a SUT Operator, I want to see the messages exchanged between two sytems under test

As a SUT operator, when I execute a test run through an intermediary tool that captures the messages exchanged between the two systems under test, I shall be able to see the messages that have been captured to select the ones that are relevant.

When I am executing a test case, for each test step, I shall see the list of messages that have been captured and that are relevant for the test step. The messages that are displayed shall be selected based on 

• The timestamp (between the start time of the test or test step and now);
• The sending and receiving endpoints;
• The message type (or at least transaction or protocol if the message type cannot be identified)

For each message, I shall see:

• Timestamp,
• Sender (Ideally the tool resolves the system's keyword based on the hostname, or hostname, or IP address),
• Receiver (Ideally the tool resolves the system's keyword based on the hostname, or hostname, or IP address),
• Message type.

The information used as "message type" may vary depending on the underlying protocol:

• For HL7v2: use content of MSH-9 (message type) + MSH-12 (HL7v2 version)
• For HTTP SOAP: use the Action element of the SOAP header
• For HTTP RESTful: Operation (HTTP VERB) + Resource type
• For DICOM: Action and SOP Class
• For Syslog: MSGID and optionally when MSGID = "IHE+RFC-3881", the value AuditEvent/EventIdentification/EventTypeCode@csd-code
