        create_mock
        expect
        replay
        verify
        reset
    );
    
    my $mock = create_mock();
    expect($mock->foo(1))->and_scalar_return('a');
    expect($mock->foo(2))->and_scalar_return('b');
    replay($mock);
    $mock->foo(1); # return 'a'
    $mock->foo(2); # return 'b'
    $mock->foo(3); # Unexpected method call.(A test is failed)
    verify($mock); # verify all expectations is invoked.
    
    reset($mock);
    expect($mock->foo(1, 2)->and_array_return('a', 'b');
    expect($mock->foo({ value => 3 })->and_array_return('c');
    replay($mock);
    $mock->foo(1, 2); # return ('a', 'b')
    $mock->foo({ value => 3 }); # return ('c')
    verify($mock);
    
    reset($mock);
    expect($mock->foo(1))->and_scalar_return('a');
    expect($mock->foo(1))->and_scalar_return('b');
    replay($mock);
    $mock->foo(1); # return 'a'
    $mock->foo(1); # return 'b'
    $mock->foo(1); # Unexpected method call.(A test is failed)

DESCRIPTION ^

This is mock library modeled on 'EasyMock' in Java.

FUNCTIONS ^

create_mock([$module_name|$object])

Creates a mock object. If specified the $module_name then a isa($module_name) method of the mock object returns true.

expect($expectation)

Record a method invocation and behavior.

The following example is expecting the foo method invocation with $arguments and a result of the invocation is 123.

    expect($mock->foo($arguments))
        ->and_scalar_return(123);

And the next example is expecting the foo method invocation without an argument and a result of the invocation is (1, 2, 3).

    expect($mock->foo())
        ->and_array_return(1, 2, 3);

A list of and_* methods.

and_scalar_return($value)

Add scalar result to the expectation.

and_array_return(@values)

Add array result to the expectation.

and_die([$message])

Add die behavior to the expectation.

and_stub_scalar_return($value)

Set scalar result as a stub to the expectation.

and_stub_array_return(@values)

Set array result as a stub to the expectation.

and_stub_die([$message])

Set die behavior as as stub to the expectation.

replay($mock [, $mock2 ...])

Replay the mock object behaviors which is recorded by the expect function.

    replay($mock);

verify($mock)

Verify the mock method invocations.

reset($mock)

Reset the mock.
