Check if List is of specific size and elements of specific type
Hi,
Is there a quick and easy way to do something like:
assert listVariable == [int, int]
eg, the list is of size 2 and each element is an int?

Hi Maarten,
You could be close with this.
def listVariable = [1,2]
assert listVariable*.getClass() == [int, int]
but your assert will have to be
assert listVariable*.getClass() == [Integer, Integer]
since ints are actually the object type Integer

Thanks all for the response, this works fine. Only draw-back is that
IntelliJ gives a warning about incompatible types. Almost as if it
doesn't understand the spread operator...

I can't resist a more verbose, but more functional way:
[1,2].identity { assert size() == 2 } .every { it instanceof Integer }

Yeah, I know. :-)
One needs to get burned once or twice in order to learn (one == me,
but I imagine I'm not alone ;-) ).

@dinko yeah, that's why I choose to do my example with listVariable*.getClass()

It would in this particular example, but this may be dangerous for
some other cases. Try e.g. this:
[1, [:], [class: 1]]*.class

It would in this particular example, but this may be dangerous for
some other cases. Try e.g. this:
[1, [:], [class: 1]]*.class

Would this work?
listVariable*.class == [Integer, Integer]
