PHPUnit's returnValueMap not yielding expected results

Question

I\'m trying to use PHPUnit\'s returnValueMap() to stub out the results of a read. It isn\'t yielding the expected results, but an equivalent returnCallback() does. I\'ve made

Answer 1

The Problem seems to lie either somewhere else in the code or might be an issue with an old PHPUnit version.

For me it works using this code:

cat EnterpriseTest.php

getMock('Enterprise', array('field'));
        $enterprise->expects($this->any())
            ->method('field')
            ->will($this->returnValueMap(array(
                array('subscription_id', null),
                array('name', 'Monday Farms')
            )))
        ;
        $enterprise->subscribe('basic');        
    }

}

class Enterprise {

    public function field($name) {
    }

    public function subscribe() {
        echo 'Subscription ID: ';
        var_dump($this->field('subscription_id'));
        echo 'Name: ';
        var_dump($this->field('name'));
    }

}

Output:

phpunit-dev EnterpriseTest.php 
PHPUnit 3.7.6 by Sebastian Bergmann.

.Subscription ID: NULL
Name: string(12) "Monday Farms"

OK (1 test, 1 assertion)

So while I can't tell why it doesn't work I can at least tell you that you are doing it right and that you've understood returnValueMap correctly :)
