Interface Summary

Interface	Description
CustomSubjectBuilder.Factory<CustomSubjectBuilderT extends CustomSubjectBuilder>	In a fluent assertion chain, the argument to the "custom" overload of about, the method that specifies what kind of Subject to create.
ExpectFailure.SimpleSubjectBuilderCallback<S extends Subject<S,A>,A>	A "functional interface" for expectFailureAbout() to invoke and capture failures.
ExpectFailure.StandardSubjectBuilderCallback	A "functional interface" for expectFailure() to invoke and capture failures.
FailureStrategy	Defines what to do when a check fails.
Ordered	Returned by calls like IterableSubject.containsExactly(java.lang.Object...), Ordered lets the caller additionally check that the expected elements were present in the order they were passed to the previous calls.
Subject.Factory<SubjectT extends Subject<SubjectT,ActualT>,ActualT>	In a fluent assertion chain, the argument to the common overload of about, the method that specifies what kind of Subject to create.

Class Summary

Class	Description
AtomicLongMapSubject	Propositions for AtomicLongMap subjects.
BigDecimalSubject	Propositions for BigDecimal typed subjects.
BooleanSubject	Propositions for boolean subjects.
ClassSubject	Propositions for Class subjects.
ComparableSubject<S extends ComparableSubject<S,T>,T extends Comparable>	Propositions for Comparable typed subjects.
Correspondence<A,E>	Determines whether an instance of type A corresponds in some way to an instance of type E.
CustomSubjectBuilder	In a fluent assertion chain, exposes one or more "custom" that methods, which accept a value under test and return a Subject.
DefaultSubject
DoubleSubject	Propositions for Double subjects.
DoubleSubject.TolerantDoubleComparison	A partially specified check about an approximate relationship to a double subject using a tolerance.
Expect	A TestRule that batches up all failures encountered during a test, and reports them all together at the end (similar to ErrorCollector).
ExpectFailure	A utility for testing that assertions against a custom Subject fail when they should, plus a utility to assert about parts of the resulting failure messages.
Fact	A string key-value pair in a failure message, such as "expected: abc" or "but was: xyz."
FailureMetadata	An opaque, immutable object containing state from the previous calls in the fluent assertion chain.
FloatSubject	Propositions for Float subjects.
FloatSubject.TolerantFloatComparison	A partially specified check about an approximate relationship to a float subject using a tolerance.
GuavaOptionalSubject	Propositions for Guava Optional subjects.
IntegerSubject	Propositions for Integer subjects.
IntStreamSubject	Propositions for IntStream subjects.
IterableSubject	Propositions for Iterable subjects.
IterableSubject.UsingCorrespondence<A,E>	A partially specified check in which the actual elements (normally the elements of the Iterable under test) are compared to expected elements using a Correspondence.
ListMultimapSubject	Type-specific extensions of Multimap subjects for ListMultimap subjects.
LongStreamSubject	Propositions for LongStream subjects.
LongSubject	Propositions for long subjects.
MapSubject	Propositions for Map subjects.
MathUtil	Math utilities to be shared by numeric subjects.
MultimapSubject	Propositions for Multimap subjects.
MultisetSubject	Propositions for Multiset subjects.
ObjectArraySubject<T>	A Subject for Object[] and more generically T[].
OptionalDoubleSubject	Propositions for Java 8 OptionalDouble subjects.
OptionalIntSubject	Propositions for Java 8 OptionalInt subjects.
OptionalLongSubject	Propositions for Java 8 OptionalLong subjects.
OptionalSubject	Propositions for Java 8 Optional subjects.
PathSubject	Assertions for Path instances.
PrimitiveBooleanArraySubject	A Subject for boolean[].
PrimitiveByteArraySubject	A Subject for byte[].
PrimitiveCharArraySubject	A Subject for char[].
PrimitiveDoubleArraySubject	A Subject for double[].
PrimitiveDoubleArraySubject.DoubleArrayAsIterable	A partially specified check for doing assertions on the array similar to the assertions supported for Iterable subjects, in which the elements of the array under test are compared to expected elements using either exact or tolerant double equality: see PrimitiveDoubleArraySubject.usingExactEquality() and PrimitiveDoubleArraySubject.usingTolerance(double).
PrimitiveDoubleArraySubject.TolerantPrimitiveDoubleArrayComparison	A partially specified check about an approximate relationship to a double[] subject using a tolerance.
PrimitiveFloatArraySubject	A Subject for float[].
PrimitiveFloatArraySubject.FloatArrayAsIterable	A partially specified check for doing assertions on the array similar to the assertions supported for Iterable subjects, in which the elements of the array under test are compared to expected elements using either exact or tolerant float equality: see PrimitiveFloatArraySubject.usingExactEquality() and PrimitiveFloatArraySubject.usingTolerance(double).
PrimitiveFloatArraySubject.TolerantPrimitiveFloatArrayComparison	A partially specified check about an approximate relationship to a float[] subject using a tolerance.
PrimitiveIntArraySubject	A Subject for int[].
PrimitiveLongArraySubject	A Subject for long[].
PrimitiveShortArraySubject	A Subject for short[].
SetMultimapSubject	Type-specific extensions of Multimap subjects for SetMultimap subjects.
SimpleSubjectBuilder<SubjectT extends Subject<SubjectT,ActualT>,ActualT>	In a fluent assertion chain, exposes the most common that method, which accepts a value under test and returns a Subject.
SortedMapSubject	Tests for SortedMap and NavigableMap objects.
SortedSetSubject	Tests for SortedSet and NavigableSet objects.
StandardSubjectBuilder	In a fluent assertion chain, an object with which you can do any of the following: Set an optional message with StandardSubjectBuilder.withMessage(java.lang.String).
StreamSubject	Propositions for Stream subjects.
StringSubject	Propositions for string subjects.
Subject<S extends Subject<S,T>,T>	An object that lets you perform checks on the value under test.
TableSubject	Propositions for Table subjects.
ThrowableSubject	Propositions for Throwable subjects.
Truth	The primary entry point for Truth, a fluent framework for test assertions.
Truth8	A set of static methods to begin a Truth assertion chain for types that require java8.
TruthFailureSubject	Subject for AssertionError objects thrown by Truth.
TruthJUnit	Provides a way to use Truth to perform JUnit "assumptions." An assumption is a check that, if false, aborts (skips) the test.
