Testing utilities. This package is a part of the open-source Guava library.

Class	Description
AbstractPackageSanityTests	Automatically runs sanity checks against top level classes in the same package of the test that extends AbstractPackageSanityTests.
ArbitraryInstances	Supplies an arbitrary "default" instance for a wide range of types, often useful in testing utilities.
ClassSanityTester	Tester that runs automated sanity tests for any given class.
EqualsTester	Tester for equals() and hashCode() methods of a class.
EquivalenceTester<T>	Tester for Equivalence relationships between groups of objects.
FakeTicker	A Ticker whose value can be advanced programmatically in test.
ForwardingWrapperTester	Tester to ensure forwarding wrapper works by delegating calls to the corresponding method with the same parameters forwarded and return value forwarded back or exception propagated as is.
GcFinalization	Testing utilities relating to garbage collection finalization.
GcFinalization.FinalizationPredicate	A predicate that is expected to return true subsequent to finalization, that is, one of the following actions taken by the garbage collector when performing a full collection in response to System.gc(): invoking the finalize methods of unreachable objects clearing weak references to unreachable referents enqueuing weak references to unreachable referents in their reference queue
NullPointerTester	A test utility that verifies that your methods and constructors throw NullPointerException or UnsupportedOperationException whenever null is passed to a parameter whose declaration or type isn't annotated with an annotation with the simple name Nullable, CheckForNull, NullableType, or NullableDecl.
NullPointerTester.Visibility	Visibility of any method or constructor.
SerializableTester	Tests serialization and deserialization of an object, optionally asserting that the resulting object is equal to the original.
SloppyTearDown	Simple utility for when you want to create a TearDown that may throw an exception but should not fail a test when it does.
TearDown	An object that can perform a TearDown.tearDown() operation.
TearDownAccepter	Any object which can accept registrations of TearDown instances.
TearDownStack	A TearDownStack contains a stack of TearDown instances.
TestLogHandler	Tests may use this to intercept messages that are logged by the code under test.
