class Mocha::ExpectationErrorFactory

This factory determines what class of exception should be raised when Mocha detects a test failure.

This class should only be used by authors of test libraries and not by typical “users” of Mocha.

For example, it is used by +Mocha::Integration::MiniTest::Adapter+ in order to have Mocha raise a +MiniTest::Assertion+ which can then be sensibly handled by +MiniTest::Unit::TestCase+.

@see Mocha::Integration::MiniTest::Adapter

Attributes

exception_class[RW]

@!attribute ::exception_class

Determines what class of exception should be raised when Mocha detects a test failure.

This attribute may be set by authors of test libraries in order to have Mocha raise exceptions of a specific class when there is an unexpected invocation or an unsatisfied expectation.

By default a +Mocha::ExpectationError+ will be raised.

@return [Exception] class of exception to be raised when an expectation error occurs
