Re: Check if List is of specific size and elements of specific type

@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

Would this work?

listVariable*.class == [Integer, Integer]

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

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?
