I am using Codeception\Util\Stub to create unit tests. And I want to be sure that my method called several times. For this I am using method 'exactly'.
Example:
use \UnitTester;
use \Codeception\Util\Stub as StubUtil;
class someCest
{
public function testMyTest(UnitTester $I)
{
$stub = StubUtil::makeEmpty('myClass', [
'myMethod' => StubUtil::exactly(2, function () { return 'returnValue'; })
]);
$stub->myMethod();
}
}
As you can see I called myMethod once. But test passed. The same problem with method ::once , because this method is using the same class PHPUnit_Framework_MockObject_Matcher_InvokedCount ('matcher' below). Test will fail only if I will call more then expected times ( >2 ). Because matcher's method 'invoked' checks if count more then expected. But can't see if someone call matcher's method 'verify' to check if myMethod called less then expected.
Sorry stackoverflow, this is my first question.
UPDATE
My fast and BAD temporary solution:
Add stub into helper
$I->addStubToVerify($stub);
Add method into helper to validate:
protected $stubsToVerify = [];
public function verifyStubs()
{
foreach ($this->stubsToVerify as $stub) {
$stub->__phpunit_getInvocationMocker()->verify();
}
return $this;
}
Call this method in Cest's method _after():
public function _after(UnitTester $I)
{
$I->verifyStubs();
}
Instead of use \Codeception\Util\Stub
to Expected::once()
, modify your unit tests to extends \Codeception\Test\Unit
then use $this->make()
or $this->makeEmpty()
to create your stubs. It will works as you expect ;)
For example:
class MyProcessorTest extends \Codeception\Test\Unit
{
public function testSomething()
{
$processor = new MyProcessor(
$this->makeEmpty(EntityManagerInterface::class, [
'remove' => Expected::never(),
'persist' => Expected::once(),
'flush' => Expected::once(),
])
);
$something = $this->somethingFactory(Processor::OPERATION_CREATE);
$processor->process($something);
}
}
Cheers!
You need to pass $this
as a third parameter to makeEmpty
:
$stub = StubUtil::makeEmpty('myClass', [
'myMethod' => StubUtil::exactly(2, function () { return 'returnValue'; })
], $this);
