public class IteratorTest<B extends Iterator<?>>
extends ObjectTest<B>

Test methods to check the contract of iterator implementing classes.

Constructor Summary

protected

IteratorTest(B testObject) Creates a new test with the specified candidate.

Method Summary

protected void	assertUnmodifying() Calls all modifying methods of the underlying iterator and checks if they throw an UnsupportedOperationException.
protected static IteratorTest<Iterator<?>>	getInstance(Iterator<?> testObject) Creates a new test with the specified candidate.
protected void	modifyAtStartTest() Asserts that a call of remove before next throws an IllegalStateException.
protected void	readTest() Performs all tests that do not change the collection underlying the iterator.

Constructor Detail

IteratorTest

protected IteratorTest(B testObject)

Creates a new test with the specified candidate.

Parameters:

testObject - the candidate of the test

Throws:

NullPointerException - if the specified test objects is null.

Method Detail

getInstance

protected static IteratorTest<Iterator<?>> getInstance(Iterator<?> testObject)

Creates a new test with the specified candidate.

Parameters:

testObject - the candidate of the test

Throws:

NullPointerException - if the specified test objects is null.

assertUnmodifying

protected void assertUnmodifying()

Calls all modifying methods of the underlying iterator and checks if they throw an UnsupportedOperationException.

Throws:

AssertionFailedError - if any of the called operations did not throw an UnsupportedOperationException

readTest

protected void readTest()

Performs all tests that do not change the collection underlying the iterator. For a simple iterator this is testing that trying to call next at the end throws an NoSuchElementException.

Throws:

AssertionFailedError - if the test object does not pass the test.

NoSuchElementException - if next() returns no element although hasNext() was true.

modifyAtStartTest

protected void modifyAtStartTest()

Asserts that a call of remove before next throws an IllegalStateException.

Throws:

AssertionFailedError - if the test object does not pass the test.
