Configuring multiple methods in PHPUnit mock objects - php

Question

I am trying to create a mock object in PHP and PHPUnit. So far, I have this:
$object = $this->getMock('object',
array('set_properties',
'get_events'),
array(),
'object_test',
null);
$object
->expects($this->once())
->method('get_events')
->will($this->returnValue(array()));
$mo = new multiple_object($object);
Ignoring my hideously ambiguous object names for the minute, I understand that what I've done is
- Created a mock object, with 2 methods to configure,
- Configured the 'get_events' method to return a blank array, and
- Dropped the mock into the constructor.
What I'd like to do now is configure the second method, but I can't find anything explaining how to do that. I want to do something like
$object
->expects($this->once())
->method('get_events')
->will($this->returnValue(array()))
->expects($this->once())
->method('set_properties')
->with($this->equalTo(array()))
or some such, but that doesn't work. How should I do that?
Tangentially, does this indicate I've structured my code poorly, if I need to configured more than one method to test?

Answer 1

I don't have any experience with PHPUnit, but my guess would be something like this:
$object
->expects($this->once())
->method('get_events')
->will($this->returnValue(array()));
$object
->expects($this->once())
->method('set_properties')
->with($this->equalTo(array()));
Have you tried it already?
Edit:
Ok, by doing some code search, I found some examples that might help you out
Check this example
They use it like this:
public function testMailForUidOrMail()
{
$ldap = $this->getMock('Horde_Kolab_Server_ldap', array('_getAttributes',
'_search', '_count',
'_firstEntry'));
$ldap->expects($this->any())
->method('_getAttributes')
->will($this->returnValue(array (
'mail' =>
array (
'count' => 1,
0 => 'wrobel#example.org',
),
0 => 'mail',
'count' => 1)));
$ldap->expects($this->any())
->method('_search')
->will($this->returnValue('cn=Gunnar Wrobel,dc=example,dc=org'));
$ldap->expects($this->any())
->method('_count')
->will($this->returnValue(1));
$ldap->expects($this->any())
->method('_firstEntry')
->will($this->returnValue(1));
(...)
}
Maybe your problem is somewhere else?
Let me know if that helped.
Edit2:
Can you try this:
$object = $this->getMock('object', array('set_properties','get_events'));
$object
->expects($this->once())
->method('get_events')
->will($this->returnValue(array()));
$object
->expects($this->once())
->method('set_properties')
->with($this->equalTo(array()));

Answer 2

The people looking for a solution to call the "same" method on the mock object multiple times, possibly with different parameters and return values, can use #Cody A. Ray's answer from this post.
Here is the answer from the post in case the links ever become invalid:
For others who are looking to both match input parameters and provide return values for multiple calls.. this works for me:
$mock
->method('myMockedMethod')
->withConsecutive([$argA1, $argA2], [$argB1, $argB2], [$argC1, $argC2])
->willReturnOnConsecutiveCalls($retValue1, $retValue2, $retValue3);
