How do Mockito matchers work?
...you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when or verify, but Mockito can't check that automatically.
You can check manually with Mockito...

Performance optimization strategies of last resort [closed]
...t's hard to sample, so I give it 10 times as much work to do, but the following times are based on the original workload.
More diagnosis reveals that it is spending time in queue-management. In-lining these reduces the time to 7 seconds.
Now a big time-taker is the diagnostic printing I had been d...
Expand a random range from 1–5 to 1–7
... subtracting 4 would make it (-3...21), but in this case it becomes (1, 6, 11, 16, 21), so the end points are correct but there are four big holes: (2..5), (7..10), (12..15), (17..21). Finally you do mod 7 and add 1, giving (2, 7, 5, 3, 1). So neither 4 nor 6 ever occur. But (see above shortcut) we ...

Using @property versus getters and setters
...
The short answer is: properties wins hands down. Always.
There is sometimes a need for getters and setters, but even then, I would "hide" them to the outside world. There are plenty of ways to do this in Python (getattr, setattr, __getattribute__, etc..., ...
Why should I avoid using Properties in C#?
...
write-only; field access is always
readable and writable.
This is a win for properties, since you have more fine-grained control of access.
A property method may throw an
