Class LiteProtoSubject

  • Direct Known Subclasses:
    ProtoSubject
    @CheckReturnValue
public class LiteProtoSubject
extends Subject
    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 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

      • isEqualTo

        public void isEqualTo​(@Nullable Object expected)
        Checks whether the MessageLite is equivalent to the argument, using the standard equals() implementation.
        Overrides:
        isEqualTo in class Subject

      • isEqualTo

        @Deprecated
public void isEqualTo​(@Nullable 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. Or, if you are passing null, use Subject.isNull().

      • isNotEqualTo

        @Deprecated
public void isNotEqualTo​(@Nullable 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. Or, if you are passing null, use Subject.isNotNull().

      • 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.
