Class AbstractTestSortedSet

public abstract class AbstractTestSortedSet extends AbstractTestSet

Abstract test class for {@link SortedSet} methods and contracts.

To use, subclass and override the {@link #makeEmptySet()} method. You may have to override other protected methods if your set is not modifiable, or if your set restricts what kinds of elements may be added; see {@link AbstractTestCollection} for more details.

Since: Commons Collections 3.0

Nested Class Summary

Constructor Summary
	AbstractTestSortedSet(String name) JUnit constructor.

Method Summary
BulkTest	bulkTestSortedSetHeadSet() Bulk test {@link SortedSet#headSet(Object)}.
BulkTest	bulkTestSortedSetSubSet() Bulk test {@link SortedSet#subSet(Object, Object)}.
BulkTest	bulkTestSortedSetTailSet() Bulk test {@link SortedSet#tailSet(Object)}.
SortedSet	getConfirmedSortedSet() Return the {@link AbstractTestCollection#confirmed} fixture, but cast as a SortedSet.
Object[]	getFullNonNullElements() Override to return comparable objects.
Object[]	getOtherNonNullElements() Override to return comparable objects.
boolean	isNullSupported() Overridden because SortedSets don't allow null elements (normally).
Collection	makeConfirmedCollection() Returns an empty {@link TreeSet} for use in modification testing.
void	verify() Verification extension, will check the order of elements, the sets should already be verified equal.

Constructor Detail

AbstractTestSortedSet

public AbstractTestSortedSet(String name)

JUnit constructor.

Parameters: name name for test

Method Detail

bulkTestSortedSetHeadSet

public BulkTest bulkTestSortedSetHeadSet()

Bulk test {@link SortedSet#headSet(Object)}. This method runs through all of the tests in {@link AbstractTestSortedSet}. After modification operations, {@link #verify()} is invoked to ensure that the set and the other collection views are still valid.

Returns: a {@link AbstractTestSet} instance for testing a headset.

bulkTestSortedSetSubSet

public BulkTest bulkTestSortedSetSubSet()

Bulk test {@link SortedSet#subSet(Object, Object)}. This method runs through all of the tests in {@link AbstractTestSortedSet}. After modification operations, {@link #verify()} is invoked to ensure that the set and the other collection views are still valid.

Returns: a {@link AbstractTestSet} instance for testing a subset.

bulkTestSortedSetTailSet

public BulkTest bulkTestSortedSetTailSet()

Bulk test {@link SortedSet#tailSet(Object)}. This method runs through all of the tests in {@link AbstractTestSortedSet}. After modification operations, {@link #verify()} is invoked to ensure that the set and the other collection views are still valid.

Returns: a {@link AbstractTestSet} instance for testing a tailset.

Returns: false

makeConfirmedCollection

public Collection makeConfirmedCollection()

Returns an empty {@link TreeSet} for use in modification testing.

Returns: a confirmed empty collection

verify

public void verify()

Verification extension, will check the order of elements, the sets should already be verified equal.
