Ricochet Testing Specification

This documents outlines each scenario this library must correctly handle and links it to the automated test that exercises that functionality.

Version Negotiation

Open

File: iricochet_test.go

This stub test exercises the Open() function. TestRicochetOpen, and in cases where the server returns a bad version, TestRicochetOpenWithError, and where there is no server at all TestRicochetOpenWithNoServer - in both cases Open should return an error.

Inbound

File: inbound_version_negotiation_test.go

Invalid Protocol

If the inbound listener receives:

  • Less than 4 bytes (TestBadProtcolLength)
  • The first 2 bytes are not equal ot 0x49 and 0x4D
  • A number of supported Versions < 1 (TestNoSupportedVersions, TestInvalidVersionList)

Then it must close the connection.

No Compatible Version Found

If the inbound listener does not receive a compatible version in the list of supported versions. Then is must close the connection. TestNoCompatibleVersions

Successful Version Negotiation

Assuming the inbound listener receives a valid protocol message, and that message contains a known supported version. Then the connection should remain open. TestNegotiateInboundVersions

Outbound

File: outbound_version_negotiation_test.go

No Compatible Version Found

If the outbound connection receives a response that does not match one of the versions they sent out in their supporting list. Then then must close the connection TestInvalidResponse , TestInvalidServer

Successful Version Negotiation

Assuming the outbound connection receives a valid protocol message, and that message contains a known supported version. Then the connection should remain open. TestOutboundVersionNegotiation
