Review Comment:
These values are only needed for the `raftGroupListener`. Shall we move it
into the same lambda below? Also, I think the lambda itself should be extracted
into a method

I don't understand. We don't expect any other values, but yet we later
explicitly check for them in `transactionAlreadyFinished`. What am I missing?

What do you mean by `specific`?

Why do we need this `CountExpectation` class? Can we just add a bunch of
`Executables` directly?

I would suggest to extract this test in a separate class, because it will
become super huge if we will be adding all commands here. But I don't insist.

We can save us some indentation here:
```
