Interface CollectionTests.RetainAllTests<T>

Type Parameters:

T - The element type of the collection to test.

All Superinterfaces:

CollectionTests<T>, IterableTests<T>

All Known Subinterfaces:

MapTests.EntrySetTests.RetainAllTests<K,V>, MapTests.KeySetTests.RetainAllTests<K,V>, MapTests.ValuesTests.RetainAllTests<K,V>

Enclosing interface:

CollectionTests<T>

@TestInstance(PER_CLASS)
@DisplayName("retainAll(Collection)")
public static interface CollectionTests.RetainAllTests<T>
extends CollectionTests<T>

Contains tests for Collection.retainAll(Collection).

By default, the tests in this interface assume that calling Collection.retainAll(Collection) with a collection containing null or an instance of an incompatible type will simply ignore the null and incompatible element. If either is not the case, annotate your class with ContainsNullNotSupported and/or ContainsIncompatibleNotSupported
