Method Detail

getFailureStrategy

protected FailureStrategy getFailureStrategy()

fail

public void fail()

Triggers the failure strategy with an empty failure message

fail

public void fail(@Nullable
                 String format,
                 Object... args)

Triggers the failure strategy with the given failure message

withFailureMessage

public abstract T withFailureMessage(@Nullable
                                     String failureMessage)

Overrides the failure message of the subsequent subject's propositions.

Parameters:

failureMessage - a descriptive message.

Returns:

A custom verb which will show the descriptive message along with the normal failure text.

delegation.DelegationTest

withFailureMessage

public abstract T withFailureMessage(@Nullable
                                     String format,
                                     Object... args)

Overrides the failure message of the subsequent subject's propositions.

Parameters:

format - a descriptive message with formatting template content.

args - object parameters to be substituted into the message template.

Returns:

A custom verb which will show the descriptive message along with the normal failure text.

about

public <S extends Subject<S,T>,T,SF extends SubjectFactory<S,T>> AbstractVerb.DelegatedVerb<S,T> about(SF factory)

The recommended method of extension of Truth to new types, which is documented in delegation.DelegationTest.

Parameters:

factory - a SubjectFactory<S, T> implementation

Returns:

A custom verb for the type returned by the SubjectFactory

delegation.DelegationTest

about

public <V extends AbstractDelegatedVerb<V>> V about(DelegatedVerbFactory<V> factory)

A generic, advanced method of extension of Truth to new types, which is documented on DelegatedVerbFactory. Extension creators should prefer SubjectFactory if possible.

Type Parameters:

V - the type of AbstractDelegatedVerb to return

Parameters:

factory - a DelegatedVerbFactory<V> implementation

Returns:

A custom verb of type <V>
