phpunit mock - 方法不存在

Question

I recently updated PHPunit from 5.3 to 5.5 in an IntegrationTestCase of an app that is CakePhp 3.x based. and I don't understand how to update my mock generation scripts.

Originally I created my mock like this:

$stub = $this->getMock('SomeClass', array('execute'));
$stub->method('execute')
     ->will($this->returnValue($this->returnUrl));

After the change to PHPUnit 5.5 this got me the following warning:

PHPUnit_Framework_TestCase::getMock() is deprecated,
use PHPUnit_Framework_TestCase::createMock()
or PHPUnit_Framework_TestCase::getMockBuilder() instead

In order to fix this warning I changed the mock-generation to:

$stub = $this->getMockBuilder('SomeClass', array('execute'))->getMock();
$stub->method('execute')
     ->will($this->returnValue($this->returnUrl));```

Now I get the following error message when running the test:

exception 'PHPUnit_Framework_MockObject_RuntimeException' 
with message 'Trying to configure method "execute" which cannot be
configured because it does not exist, has not been specified, 
is final, or is static'

Anybody know, how to avoid this error? Thank you.

PHPUnit_Framework_TestCase::getMockBuilder() only takes one (1) argument, the class name. The methods to mock are ment to be defined via the returned mock builder objects setMethods() method.

$stub = $this
    ->getMockBuilder('SomeClass')
    ->setMethods(['execute'])
    ->getMock();
