Test setup enhancements?

Is there a way we can enhance the tests? I find pretty difficult to work with them. Scenarios:
- When something is failing I can not run only that failing test, therefore debugging is more complicated
- When stuff fails, printing debug messages to stderr or stdout it will not help you because
- They are not displayed
- They change the expected output of the program and therefore the test fail because it checks std*

On top of that there is a weird thing that happens to me. Sometimes the tests still broken even if I reset the repo removing all of my changes. Here is the output:

```
SIGTERM in no daemon mode causes a stop...pass
(test setup) use server3.js...pass
(test setup) mkdir foo...pass
cli accepts non-default args...
assert.js:92
throw new assert.AssertionError({
^
AssertionError: actual:
unable to connect to ipc-file `some/dir/ipc`

1. the ipc file specified is invalid, or
2. the daemon process died unexpectedly

expected:
Bootup. booting: 0, online: 0, dying: 0, new_online: 0
SpawnNew. booting: 1, online: 0, dying: 0, new_online: 0
SpawnNew. booting: 2, online: 0, dying: 0, new_online: 0

```

Test will not pass even if I reset the repo.

Some ideas:
- Group different test into different files
- Add events so we can trace application behavior like
- Split unit test from system/integration tests

I understand that these changes implies a lot of work but I will happily contribute to it if you are open to it.
