Does it compile on your machine? I have this error:

error: unexpected end of macro invocation
   --> src/dev/simulation.rs:197:13

    |             ^^^^^^^^^ missing tokens in macro arguments

Great! Do you think you could also enable logging in integration tests? Just to demonstrate that it's possible to trace state changes through the execution.

Only enabled it for the first test since the other two do not use simulation.
