Method Detail

underlyingType

protected String underlyingType()

listRepresentation

protected List<?> listRepresentation()

Returns a List representation suitable for displaying in a string.

isEqualTo

public void isEqualTo(Object expected)

A proposition that the provided Object[] is an array of the same length and type, and contains elements such that each element in expected is equal to each element in the subject, and in the same position.

Overrides:

isEqualTo in class Subject<ObjectArraySubject<T>,T[]>

isNotEqualTo

public void isNotEqualTo(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<ObjectArraySubject<T>,T[]>

asList

public IterableSubject asList()

isEmpty

public void isEmpty()

Fails if the array is not empty (i.e. array.length != 0).

isNotEmpty

public void isNotEmpty()

Fails if the array is empty (i.e. array.length == 0).

hasLength

public void hasLength(int length)

Fails if the array does not have the given length.

Throws:

IllegalArgumentException - if length < 0

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 com.google.common.truth.AbstractArraySubject<S,T>,T>
