protected Fail()

This constructor is protected to make it possible to subclass this class. Since all its methods are static, there is no point on creating a new instance of it.

Method Detail

Throws:

AssertionError - without any message.

                                  Object other)

Throws an AssertionError if the given objects are equal.

Parameters:

fail

public static AssertionError fail(String message)

Fails with the given message.

Note: This method appears to return AssertionError, but it is really not the case, since the exception is thrown and not returned. In version 2.0 the return type of this method will change to void. Since we cannot create an overloaded version with return type void, we cannot deprecate this method. Please pretend this method does not return anything :)

Parameters:

message - error message.

Returns:

the thrown AssertionError.

Throws:

AssertionError - with the given message.

failure

public static AssertionError failure(String message)
