...epositories reasonably for a simple reason: it's way to cumbersome to mock all the parts of the JPA API we invoke to bootstrap the repositories. Unit tests don't make too much sense here anyway, as you're usually not writing any implementation code yourself (see the below paragraph on custom impleme...
What does immutable mean?
...our second alert it will show "foo" instead of oo.
Does it mean, when calling methods on
a string, it will return the modified

title = "Error";
}
This kind of shorthand trick with boolean expressions is common in Perl too. With the...
