Class LiteProtoSubject<S extends LiteProtoSubject<S,M>,M extends com.google.protobuf.MessageLite>

java.lang.Object

com.google.common.truth.Subject<S,M>

com.google.common.truth.extensions.proto.LiteProtoSubject<S,M>

Type Parameters:

S - Subject class type.

M - MessageLite type.

Direct Known Subclasses:

ProtoSubject

@CheckReturnValue
public class LiteProtoSubject<S extends LiteProtoSubject<S,M>,M extends com.google.protobuf.MessageLite>
extends Subject<S,M>

Truth subjects for the Lite version of Protocol Buffers.

LiteProtoSubject supports versions 2 and 3 of Protocol Buffers. Due to the lack of runtime descriptors, its functionality is limited compared to ProtoSubject, in particular in performing detailed comparisons between messages.

Method Summary

Modifier and Type	Method and Description
protected String	actualCustomStringRepresentation() Supplies the direct string representation of the actual value to other methods which may prefix or otherwise position it in an error message.
void	hasAllRequiredFields() Checks whether the subject has all required fields set.
void	isEqualTo(com.google.protobuf.MessageLite.Builder builder) Deprecated. A Builder can never compare equal to a MessageLite instance. Use build(), or buildPartial() on the argument to get a MessageLite for comparison instead.
void	isEqualTo(Object expected) Checks whether the MessageLite is equivalent to the argument, using the standard equals() implementation.
void	isEqualToDefaultInstance() Checks whether the subject is a MessageLite with no fields set.
void	isNotEqualTo(com.google.protobuf.MessageLite.Builder builder) Deprecated. A Builder will never compare equal to a MessageLite instance. Use build(), or buildPartial() on the argument to get a MessageLite for comparison instead.
void	isNotEqualTo(Object expected) Fails if the subject is equal to the given object.
void	isNotEqualToDefaultInstance() Checks whether the subject is not equivalent to a MessageLite with no fields set.
IntegerSubject	serializedSize() Returns an IntegerSubject on the serialized size of the MessageLite.

Method Detail

actualCustomStringRepresentation

protected String actualCustomStringRepresentation()

Description copied from class: Subject

Supplies the direct string representation of the actual value to other methods which may prefix or otherwise position it in an error message. This should only be overridden to provide an improved string representation of the value under test, as it would appear in any given error message, and should not be used for additional prefixing.

Subjects should override this with care.

By default, this returns String.ValueOf(getActualValue()).

Overrides:

actualCustomStringRepresentation in class Subject<S extends LiteProtoSubject<S,M>,M extends com.google.protobuf.MessageLite>

isEqualTo

public void isEqualTo(@NullableDecl
                      Object expected)

Checks whether the MessageLite is equivalent to the argument, using the standard equals() implementation.

Overrides:

isEqualTo in class Subject<S extends LiteProtoSubject<S,M>,M extends com.google.protobuf.MessageLite>

isEqualTo

@Deprecated
public void isEqualTo(@NullableDecl
                                  com.google.protobuf.MessageLite.Builder builder)

Deprecated. A Builder can never compare equal to a MessageLite instance. Use build(), or buildPartial() on the argument to get a MessageLite for comparison instead.

isNotEqualTo

public void isNotEqualTo(@NullableDecl
                         Object expected)

Description copied from class: Subject

Fails if the subject is equal to the given object. The meaning of equality is the same as for the Subject.isEqualTo(java.lang.Object) method.

Overrides:

isNotEqualTo in class Subject<S extends LiteProtoSubject<S,M>,M extends com.google.protobuf.MessageLite>

isNotEqualTo

@Deprecated
public void isNotEqualTo(@NullableDecl
                                     com.google.protobuf.MessageLite.Builder builder)

Deprecated. A Builder will never compare equal to a MessageLite instance. Use build(), or buildPartial() on the argument to get a MessageLite for comparison instead.

isEqualToDefaultInstance

public void isEqualToDefaultInstance()

Checks whether the subject is a MessageLite with no fields set.

isNotEqualToDefaultInstance

public void isNotEqualToDefaultInstance()

Checks whether the subject is not equivalent to a MessageLite with no fields set.

hasAllRequiredFields

public void hasAllRequiredFields()

Checks whether the subject has all required fields set. Cannot fail for a proto built with build(), which itself fails if required fields aren't set.

serializedSize

public IntegerSubject serializedSize()

Returns an IntegerSubject on the serialized size of the MessageLite.

Assertions can then be changed on the serialized size, to support checks such as assertThat(myProto).serializedSize().isAtLeast(16), etc.
