ZF2 PHPUnit
Ballon Effect
Testing your application what you build/changed.
Retesting everything all the time is very important.
That's take a lot of time.

ZF2 PHPUnit
PhpUnit
Testing with PHPUnit means checking that your
program behaves as expected, and performing a
battery of tests.
These runnable code-fragments are called unit tests.

ZF2 PHPUnit
Installation
# pear config-set auto_discover 1
# pear install pear.phpunit.de/PHPUnit
// for code coverage
# sudo pecl install xdebug

ZF2 PHPUnit
Directory Tree
Structure

ZF2 PHPUnit
<?php
return array(
'modules' => array(
TestConfig File
//modules needed
'User',
'Products'
),
'module_listener_options' => array(
'config_glob_paths' => array(
'../../../config/autoload/{,*.}{global,local,message}.php',
),
'module_paths' => array(
'module',
'vendor',
),
),
);

Bootstrap File

ZF2 PHPUnit
<?php
namespace UserTestController;
use ZendTestPHPUnitControllerAbstractHttpControllerTestCase;
use ZendTestPHPUnitControllerAbstractControllerTestCase;
class AdminControllerTest extends AbstractControllerTestCase
{
protected $controller;
protected $request;
protected $response;
protected $routeMatch;
protected $event;
protected $loginForm;
protected $userMockObj;
protected $callSummaryForm;
protected $serviceManager;
}

ZF2 PHPUnit
public function setUp()
{
$this->serviceManager = Bootstrap::getServiceManager();
$this->controller = new AdminController();
$this->request = new Request();
$tis->routeMatch = new RouteMatch(array('controller' => 'admin'));
$this->event = new MvcEvent();
$config = $this->serviceManager->get('Config');
$routerConfig = isset($config['router']) ? $config['router'] : array();
$router = HttpRouter::factory($routerConfig);
….............
…........
}
PHPUnit supports sharing the setup code. Before a
test method is run, a template method called setUp() is
invoked. setUp() is where you create the objects
against which you will test.

ZF2 PHPUnit
Writing Tests with PHPUnit
// To test the call-summary action
public function testCallSummaryAction()
{
$this->serviceManager->setAllowOverride(true);
$this->serviceManager->setService('UserModelUserModel', $this->userMockObj);
$this->routeMatch->setParam('action', 'call-summary');
$result = $this->controller->dispatch($this->request);
$response = $this->controller->getResponse();
$this->assertEquals(200, $response->getStatusCode());
}
//To test the delete-user action
public function testDeleteUserAction()
{
$this->routeMatch->setParam('action', 'delete-user');
$result = $this->controller->dispatch($this->request);
$response = $this->controller->getResponse();
$this->assertEquals(302, $response->getStatusCode());
}

ZF2 PHPUnit
Test class should extend the class
AbstractControllerTestCase
The tests are public methods that expect no parameters
and are named test*
Inside the test methods, assertion methods such as
assertEquals() are used to assert that an actual value
matches an expected value.

ZF2 PHPUnit
The PHPUnit command-line test runner can be invoked through
the phpunit command.
# phpunit
PHPUnit 4.1.3 by Sebastian Bergmann.
..
Time: 00:00
OK (2 tests)
. Printed when the test succeeds.
F Printed when an assertion fails while running the test method.
E Printed when an error occurs while running the test method.
S Printed when the test has been skipped.
I Printed when the test is marked as being incomplete or not yet
implemented.

ZF2 PHPUnit
Incomplete Tests
public function testSomething()
{
// Stop here and mark this test as incomplete.
$this->markTestIncomplete(
'This test has not been implemented yet.‘);
}
A test as being marked as incomplete or not
yet implemented.

ZF2 PHPUnit
Fixtures
setUp() method – is called before a test method run
tearDown() method – is called after a test method run
setUp() and tearDown() will be called once for each test
method run.

ZF2 PHPUnit
Code-Coverage Analysis
How do you find code that is not yet tested?
How do you measure testing completeness?
#phpunit --coverage-html dir-name
PHPUnit 4.1.3 by Sebastian Bergmann.
....
Time: 00:00
OK (4 tests)
Generating report, this may take a moment.

ZF2 PHPUnit
Lines of code that were executed while running the tests are
highlighted green, lines of code that are executable but were not
executed are highlighted red, and "dead code" is highlighted gray.

ZF2 PHPUnit
Advantages
• Testing gives code authors and reviewers confidence
that patches produce the correct results.
• Detect errors just after code is written
• The tests are run at the touch of a button and present
their results in a clear format.
• Tests run fast
• The tests do not affect each other. If some changes
are made in one test, the results of others tests do
not change.

ZF2 PHPUnit
Disadvantages
Some people have trouble with getting started:
where to put the files, how big the scope of one
unit test is and when to write a separate testing
suite and so on.
It would be difficult to write a test for people who
are not programmers or familiar with PHP.
