John Wagenleitner created GROOVY-7960:
-----------------------------------------
Summary: IntRange iterator returns null instead of
NoSuchElementException
Key: GROOVY-7960
URL: https://issues.apache.org/jira/browse/GROOVY-7960
Project: Groovy
Issue Type: Bug
Affects Versions: 2.4.7
Reporter: John Wagenleitner
Assignee: John Wagenleitner
Priority: Minor
Calling {{next()}} on an {{IntRange}} iterator returns {{null}} when
{{hasNext{}}} returns false. As stated in a comment in the class, it should
throw {{NoSuchElementException}} to adhere to the Iterator contract.
{code}
class IntRangeItrTest extends GroovyTestCase {
void testItr() {
def itr = (1..2).iterator()
assert itr.next() == 1
assert itr.next() == 2
assert !itr.hasNext()
shouldFail(NoSuchElementException) {
itr.next() // null
}
}
}
{code}
