public class ListIteratorTest

extends IteratorTest

Test methods to check the contract of list iterator implementing classes.

Constructor Summary

protected	ListIteratorTest(List list) Creates a new test from the specified base list.
protected	ListIteratorTest(List list, int index) Creates a new test from the specified base list.

Method Summary

void	assertConsistency() Checks consistency of list iterator without moving the cursor.
protected void	assertUnmodifying() Calls all modifying methods of the underlying iterator and checks if they throw an UnsupportedOperationException.
protected void	checkConsistency() This method is called at the start of the test cycle and after each modification of the test object.
protected void	modifyAtStartTest() Asserts that a call of set before next throws an IllegalStateException.
protected void	performCycle() Calls set, remove and add.
protected void	readTest() Performs all tests that do not change the collection underlying the iterator.

Constructor Detail

ListIteratorTest

protected ListIteratorTest(List list)

Creates a new test from the specified base list.

Parameters:

list - the base list of the list iterator to test

Throws:

NullPointerException - if the specified test objects is null.

ListIteratorTest

protected ListIteratorTest(List list,
                           int index)

Creates a new test from the specified base list.

Parameters:

list - the base list of the list iterator to test

index - index of first element to be returned from the list iterator (by a call to the next method).

Throws:

IndexOutOfBoundsException - index < 0 || index > size() of base list.

NullPointerException - if the specified test objects is null.

Method Detail

assertConsistency

public void assertConsistency()

Checks consistency of list iterator without moving the cursor.

Overrides:

assertConsistency in class ObjectTest

Throws:

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

assertUnmodifying

protected void assertUnmodifying()

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

Overrides:

assertUnmodifying in class IteratorTest

Throws:

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

readTest

protected void readTest()

Description copied from class: IteratorTest

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.

Overrides:

readTest in class IteratorTest

Following copied from class: net.sf.molae.pipe.test.IteratorTest

Throws:

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

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

checkConsistency

protected void checkConsistency()

This method is called at the start of the test cycle and after each modification of the test object. This implementation calls readTest().

Throws:

AssertionFailedError - if the test object is not consistent.

performCycle

protected void performCycle()

Calls set, remove and add.

Throws:

AssertionFailedError - if the test object is not consistent.

UnsupportedOperationException - if any of the called methods is not implemented.

modifyAtStartTest

protected void modifyAtStartTest()

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

Overrides:

modifyAtStartTest in class IteratorTest

Throws:

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