Expect

public class StandardSubjectBuilder
extends Object

In a fluent assertion chain, an object with which you can do any of the following:

• Set an optional message with withMessage(java.lang.String).
• Specify the type of Subject to create with about(Subject.Factory).
• For the types of Subject built into Truth, directly specify the value under test with that(Object).

Method Detail

forCustomFailureStrategy

public static StandardSubjectBuilder forCustomFailureStrategy(FailureStrategy failureStrategy)

Returns a new instance that invokes the given FailureStrategy when a check fails. Most users should not need this. If you think you do, see the documentation on FailureStrategy.

Returns a new instance that will output the given message before the main failure message. If this method is called multiple times, the messages will appear in the order that they were specified.

Note: the arguments will be substituted into the format template using Strings.lenientFormat. Note this only supports the %s specifier.

Throws:

IllegalArgumentException - if the number of placeholders in the format string does not equal the number of given arguments

about

public final <S extends Subject<S,A>,A> SimpleSubjectBuilder<S,A> about(Subject.Factory<S,A> factory)

Given a factory for some Subject class, returns a builder whose that(actual) method creates instances of that class. Created subjects use the previously set failure strategy and any previously set failure message.

about

public final <CustomSubjectBuilderT extends CustomSubjectBuilder> CustomSubjectBuilderT about(CustomSubjectBuilder.Factory<CustomSubjectBuilderT> factory)

fail

public final void fail()

Triggers the failure strategy with an empty failure message

fail

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

Triggers the failure strategy with the given failure message
