ClassDescriptionAutomatically runs sanity checks against top level classes in the same package of the test that extends
AbstractPackageSanityTests
.Supplies an arbitrary "default" instance for a wide range of types, often useful in testing utilities.Tester that runs automated sanity tests for any given class.Thrown if the test tries to invoke a static factory method to test instance methods but the factory returned null.Thrown if the test fails to generate two distinct non-null values of a constructor or factory parameter in order to testObject.equals(java.lang.Object)
andObject.hashCode()
of the declaring class.Thrown if the test tries to invoke a constructor or static factory method but failed because the dummy value of a constructor or method parameter is unknown.AnClusterException
is a data structure that allows for some code to "throw multiple exceptions", or something close to it.CollectorTester<T,A, R> Tester forCollector
implementations.Different orderings for combining the elements of an input array, which must all produce the same result.Generates a dummy interface proxy that simply returns a dummy value for each method.Marks all "top-level" types as non-null in a way that is recognized by Kotlin.Tester for equals() and hashCode() methods of a class.Class used to test whether equals() correctly handles an instance of an incompatible class.Tester forEquivalence
relationships between groups of objects.A Ticker whose value can be advanced programmatically in test.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.Tests a single interaction against a method.Generates fresh instances of types that are different from each other (if possible).Annotates a method to generate the "empty" instance of a collection.Annotates a method to be the instance generator of a certain type.Testing utilities relating to garbage collection finalization.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 toSystem.gc()
: invoking thefinalize
methods of unreachable objects clearing weak references to unreachable referents enqueuing weak references to unreachable referents in their reference queueDisables Animal Sniffer's checking of compatibility with older versions of Java/Android.A test utility that verifies that your methods and constructors throwNullPointerException
orUnsupportedOperationException
whenever null is passed to a parameter whose declaration or type isn't annotated with an annotation with the simple nameNullable
,CheckForNull
,NullableType
, orNullableDecl
.Strategy for exception type matching used byNullPointerTester
.Looks for declaration nullness annotations and, if supported, type-use nullness annotations.Visibility of any method or constructor.Methods factored out so that they can be emulated differently in GWT.Implementation helper forEqualsTester
andEquivalenceTester
that tests for equivalence classes.Tests serialization and deserialization of an object, optionally asserting that the resulting object is equal to the original.Simple utility for when you want to create aTearDown
that may throw an exception but should not fail a test when it does.An object that can perform aTearDown.tearDown()
operation.Any object which can accept registrations ofTearDown
instances.ATearDownStack
contains a stack ofTearDown
instances.Tests may use this to intercept messages that are logged by the code under test.
