Method Details

samples

public SampleElements<Map.Entry<String, Collection<Integer>>> samples()

Description copied from interface: TestContainerGenerator

Returns the sample elements that this generate populates its container with.

Specified by:

samples in interface TestContainerGenerator<Map<String, Collection<Integer>>, Map.Entry<String, Collection<Integer>>>

create

public Map<String, Collection<Integer>> create(Object... elements)

Description copied from interface: TestContainerGenerator

Creates a new container containing the given elements. TODO: would be nice to figure out how to use E... or E[] as a parameter type, but this doesn't seem to work because Java creates an array of the erased type.

Specified by:

create in interface TestContainerGenerator<Map<String, Collection<Integer>>, Map.Entry<String, Collection<Integer>>>

createArray

public Map.Entry<String, Collection<Integer>>[] createArray(int length)

Description copied from interface: TestContainerGenerator

Helper method to create an array of the appropriate type used by this generator. The returned array will contain only nulls.

Specified by:

createArray in interface TestContainerGenerator<Map<String, Collection<Integer>>, Map.Entry<String, Collection<Integer>>>

order

public Iterable<Map.Entry<String, Collection<Integer>>> order(List<Map.Entry<String, Collection<Integer>>> insertionOrder)

Description copied from interface: TestContainerGenerator

Returns the iteration ordering of elements, given the order in which they were added to the container. This method may return the original list unchanged, the original list modified in place, or a different list.

If the order is non-deterministic, as with HashSet, this method can return its input unmodified. Provided that the test suite is built without CollectionFeature.KNOWN_ORDER, the tests will look only at the returned contents without regard for order.

Specified by:

order in interface TestContainerGenerator<Map<String, Collection<Integer>>, Map.Entry<String, Collection<Integer>>>

createKeyArray

public String[] createKeyArray(int length)

Specified by:

createKeyArray in interface TestMapGenerator<String, Collection<Integer>>

createValueArray

public Collection<Integer>[] createValueArray(int length)

Specified by:

createValueArray in interface TestMapGenerator<String, Collection<Integer>>
