Direct Known Subclasses:

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).

For more information about the methods in this class, see this FAQ entry.

For people extending Truth

You won't extend this type. When you write a custom subject, see our doc on extensions.

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.

withMessage

public final StandardSubjectBuilder withMessage(@Nullable String messageToPrepend)

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.

withMessage

public final StandardSubjectBuilder withMessage(String format,
                                                Object... args)

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,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()

Reports a failure.

To set a message, first call withMessage(java.lang.String) (or, more commonly, use the shortcut Truth.assertWithMessage(java.lang.String)).
