Tests for D-Bus binding test rig:

Tests are functions which will perform a particular transformation on the input
and return the result. They should be defined as a D-Bus signature and
description of the function:

test-introspect.xml

The SingleTests Tests and TestSignals interfaces should be implemented by the
servers. The TestClient interface should be implemented by the client.

Servers must also support:

   Peer.Ping
   Introspectable.Introspect on all objects and parent paths

Clients try and cause these to fail in the most obscure way possible. Servers
make sure all of their methods are called each run. Output format:

   Server:
      <interface.function> ok
      <interface.function> ok
      ....
      <interface.function> untested

   Client:
      <interface.function> pass
      <interface.function> pass
      ....
      <interface.function> fail <id1>
      <interface.function> fail <id2>
      report <id1>: <text description of failure>
      report <id2>: <text description of failure>


Starting clients and servers is done using Makefiles and chaining thereof. Each
binding should provide the following Makefile targets in their respective
top-level dirs:

   cross-test-compile - do any compilation necessary to run the server and client
   cross-test-server - run a server which binds to
                       org.freedesktop.DBus.Binding.TestServer. Listens and
                       answers method calls on the /Test object until Exit
                       is called. Then prints test reports.
   cross-test-client - run a client which runs comprehensive tests against 
                       the server, then calls Exit and prints test reports

Ignoring tests:

   Tests can be ignored if you know they are going to fail. This will print a
   list of ignored fails. To ignore tests create a file cross-test-ignore
   containing a list of interface.function, one per line.

A note on Signals:

   The tests involve two signals. Triggered is sent from the server to the
   client when the Trigger() method is called. The client sends Trigger to the
   server which should cause Response() to be called by the server on the
   client.
