I am not sure if I am doing something wrong or it is a bug with PHPUnit and mock objects. Basically I am trying to test if $Model->doSomething()
is called when $Model->start()
is triggered.
I am using Ubuntu in a VirtualBox, and phpunit 1.1.1 installed via pear.
The full code is below. Any help would be appreciated, it's driving me crazy.
<?php
require_once 'PHPUnit/Autoload.php';
class Model
{
function doSomething( ) {
echo 'Hello World';
}
function doNothing( ) { }
function start( ) {
$this->doNothing();
$this->doSomething();
}
}
class ModelTest extends PHPUnit_Framework_TestCase
{
function testDoSomething( )
{
$Model = $this->getMock('Model');
$Model->expects($this->once())->method('start'); # This works
$Model->expects($this->once())->method('doSomething'); # This does not work
$Model->start();
}
}
?>
The output from PHPUnit:
There was 1 failure:
1) ModelTest::testDoSomething
Expectation failed for method name is equal to <string:doSomething> when invoked 1 time(s).
Method was expected to be called 1 times, actually called 0 times.
FAILURES!
Tests: 1, Assertions: 1, Failures: 1.
As you found, you need to tell PHPUnit which methods to mock. Also, I would avoid creating expectations for methods that you are calling directly from the test. I would write the above test like this:
function testDoSomething( )
{
$Model = $this->getMock('Model', array('doSomething');
$Model->expects($this->once())->method('doSomething');
$Model->start();
}
