Zend Framework/PHPUnit: How to Stub/Mock an object method that connects to a database?
- by Andrew
In my Zend Framework project, I have a form that I am testing. In my form, a multi-select element gets its options from a model, which gets the data from the database.
public function init()
{
$this->addElement('select', 'Region_ID', array('multiOptions' => $this->getRegions()));
}
protected function getRegions()
{
$mapper = new Model_RegionMapper();
return $mapper->getFormSelectData(); //this method will try to connect to a database (or get another object that will connect to the database)
}
I tried copying the example in the PHPUnit documentation, but it doesn't seem to be working.
public function setUp()
{
$stub = $this->getMock('Model_RegionMapper');
$stub->expects($this->any())
->method('getFormSelectData')
->will($this->returnValue(array('testdata')));
}
public function testFoo()
{
//this will fail
$form = new My_Form();
}
The test fails because it is trying to find a table in the database that doesn't exist. But I don't want it to connect to the database at all. How do I correctly stub/mock this method so that it doesn't call the database?
