@GwtCompatible public enum CollectionSize
When describing the features of the collection produced by a given generator
(i.e. in a call to FeatureSpecificTestSuiteBuilder.withFeatures(Feature...)
),
this annotation specifies each of the different sizes for which a test suite
should be built. (In a typical case, the features should include ANY
.) These semantics are thus a little different
from those of other Collection-related features such as CollectionFeature
or SetFeature
.
However, when CollectionSize.Require
is used to annotate a test it
behaves normally (i.e. it requires the collection instance under test to be
a certain size for the test to run). Note that this means a test should not
require more than one CollectionSize, since a particular collection instance
can only be one size at once.
This class is GWT compatible.
