I have to preface this video by saying that I’m still a bit of a novice when it comes to unit testing (especially in Zend). Also, I feel that I wouldn’t be able to take credit for the whole implementation.
Here are some great resources on unit testing in the Zend Framework to beef up your knowledge.
- Set up a Zend Framework application using Zend_Application (including PHPUnit setup)
- Testing Zend Framework MVC Applications – phly, boy, phly
- Matthew’s pastebin
The trouble with these is that they’re mostly pre-1.8. I’ve taken the approach of using a command line instead of the IDE since this way it doesn’t matter if you’re using Zend Studio for Eclipse.
What’s covered:
- Using phpunit with MAMP
- Unit Testing Models
- Generating Code Coverage Reports
- Unit Testing Controllers
Don’t forget to grab the source code or browse it on google code.
Great video!, what about Zend_Application with modules bootstraping ?
Thx!
Thanks for the feedback Juan
I think I covered that a couple videos ago (using Zend_Tool)… or are you referring to something else?
Your website is fantastic.
If you need french help.. z-f.fr
Very nice video Jon, you are the greatest
Just wanted to drop a question,
in your model test you write
foreach ( $this->stats->getCountries() as $country )
{
if ( $country == $defaultCountry )
$this->assertEquals($country, $defaultCountry);
}
the thing is, i don’t like this if, it already answers the assertion and therefore “overiterates” the testing.
Maybe i just didn’t get the point of this test, if so tell me i’m eager to hear your reasoning
Just to finish my thought:
$isCountryAdded = in_array($defaultCountry, $this->stats->getCountries());
$this->assertTrue($isCountryAdded);
This seems to be an way to dismiss the if and therefore always have the assertion take place.
Greetings and many many thanks again for all the help with the setup & configuration of phpunit
)
Silone!
That’s a much cleaner way of doing the assertion. Thank you!
Just wondering how you would go about testing a AsyncController like the one in a previous video? I can’t seem to figure it out.
Thanks for the videos. Keep it up.
RE:Comment 6
Worked it out… my code was misleading me
Hi Jon,
I have found your website very helpful. I tried this tutorial and everything worked fina but when I run the test the test-coverage report is not created. I tried to use your source code but the same problem occure. Do you have any clue what could be possibly wrong? Thx
Hi Tom,
its possible that the phpunit.xml was mis-configured… another possibility is that you may not have permissions set to write to those particular folders. Hope that helps,

Hi Jon,
Now everything is working fine 
I found out that my xdebug was not installed
Hi Jon,
Excellent website which has been a excellent resource for me. I’m struggling a bit testing models which extend Zend_Db_Table_Abstract. I know this is all to do with the bootstrapping.
The application can access, store data etc. to the DB but it appears I have not to have been able to set up the DB correctly for my test suite.
Could you provide any assistance?
Hi Dave,
do you have a test database? or at least a database setup in your application.ini file under the ‘testing’ heading? That might be the only problem. Can you paste your exception information?
Hi Jon, thanks for getting back to me, yeah I have a test DB and it correctly setup under [testing : production] in my application.ini.
phpunit comes back with “Fatal error: Class ‘Zend_Db_Table_Abstract’ not found”
I kinda expected it would as autoloading is setup in my applications bootstrap (not test bootstrap) using
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initAutoload()
{
$autoloader = new Zend_Application_Module_Autoloader(array(
‘namespace’ => ”,
‘basePath’ => dirname(__FILE__),
));
return $autoloader;
}
}
, I just was not clear how to do this under the setup you described.
Thanks in advance
Dave
Ah… you might need to explicitly include it in the array which is passed into set_include_paths.. since Model_ might not be loaded by convention through the unit tests…
Thanks for the reply Jon, Model_ is loaded by convention, but not initializing a DB such as…
protected function _initDatabase()
{
$resource = $this->getPluginResource(‘db’);
$db = $resource->getDbAdapter();
Zend_Db_Table_Abstract::setDefaultAdapter($db);
I had a look at Matthew’s blog and frigged a similar method, only difference being in the setup method of every test cases I call the applications bootstrap (not test bootstrap file that is created with Zend Tool)but suppose I could extend a class similar to what you have here.
Excellent screencast, Jon. Many thanks! It was very useful.
Very helpfull. Thanks!
Hi,
why is Model_StatsTest extending ControllerTestCase?
Hi Martin,
ControllerTestCase is a bit of a misnomer since its not only a class that helps with setting up Zend_Test_* classes, but also helps you bootstrap your application and make it run with the same include paths etc… that you would expect if you were running the app in dev/staging/production environments. I could extend a class that would be similar that didn’t have the ability to start the front controller however it would require a more complex design for my testing framework. As long as the developer is disciplined and doesn’t run non Model-specific unit tests in StatsTest, I don’t see a problem. What do you think?
Hi question.
I downloaded MAMP but i don’t have phpunit in that directory. How can i get it?
Hi Alex,
I think things have changed since I downloaded my copy of MAMP. Here are two articles about grabbing phpunit with MAMP:
http://mark-kirby.co.uk/2009/installing-phpunit-with-mamp/
http://www.typeoneerror.com/installing-phpunit-with-mamp/
hope that helps,

I am having trouble getting my classes to auto load. Also, why is the application Bootstrap.php a class but the Zend_Test bootstrap.php is not a class. In my application Bootstrap.php file I have a function named _initAutoload() like this:
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap {
protected function _initAutoload() {
$moduleLoader = new Zend_Application_Module_Autoloader(array(‘namespace’ => ”, ‘basePath’ => APPLICATION_PATH));
}
}
But since my Zend_Test bootstrap.php file is not a class, I’m not sure how to get the autoloading to work.
Great screencast!
Hi Lee,
bootstrap.php if a procedurally-written file that is run via the phpunit.xml file. The Bootstrap.php file is specifically part of the Zend framework’s bootstrap. This includes configuration and other business that is uniform across the test and dev/test instances of your application.
I’m new to testing this way with the Zend Framework. Excellent point about the boostrap.php file being run by the phpunit XML config file. So I put this line in my appBootstrap() function in the ControllerTestCase class:
Zend_Application_Module_Autoloader(array(‘namespace’ => ”, ‘basePath’ => APPLICATION_PATH));
Now I’m trying to figure out how to get my default database adapter set up.
I tried unit testing on my vista machine and i didn’t get the coverage report. testdox is there, but no coverage. phpunit version is 3.3.9.
i did the test as vista-admin. no error messages – no report
any hints?
p.s.: sorry for my english, i’m not a nativ speaker.
You need xdebug for the coverage reports
@john:
Thanks for the links. PHPUnit and Xdebug is now running. But i have a problem. I wanted to test it and created a standart project with zend_tool and copied the tests folder from your example.
But when i now run phpunit it seems that it does nothing. No code coverage, now test and so on.
But if i try it with your example it works.
Great!!
Thanks jon
this video is excellent!! i really grateful for your share,but i want to know! how can i download it? i am looking forward to your replying!
Now I have some kind of idea about unit testing! Thanks a lot!
how was it that you set up unit testing for netbeans i am kind of lost …
hey iceangel89,
I wrote a mini tutorial about my setup on my blog — http://lebensold.net/development/unit-testing-within-the-netbeans-6-7-1-ui
Thanks Jon,
very informative !
U the man
i cant seem to get pear/phpunit working correctly on my windows 7.
when i run “pear” i get “syntax error, unexpected ‘(‘ in Unknown on line 14″ tho the help stuff comes out.
when i run “phpunit”, i get “‘”"C:\Program’ is not recognized as an internal or external command,
operable program or batch file.” tho the tests run.
Hmm can somebody tell me what i did wrong i have mamp followed the tutorials..but when i type phpunit nothing happens i dont get to see the parameters..
Thanks for your answer!
I tried to follow this video, but on windows.
I install phpunit and made a phpunit.xml file.
Then I executed phpunit –configuration phpunit.xml, but it displayed nothing.
Then I executed phpunit –bootstrap application\bootstrap.php and it displayed a die(…) message.
So, I understood, that phpunit ignored my phpunit.xml
Ok, then I started to change a bootstrap file, as I saw in video and executed phpunit –bootstrap application\bootstrap.php again.
But that moment it displaay nothing. But in video it displayed some information. (
I don’t understand a phpunit behaviour on windows. ((
Loved the tutorial. I had a bit of trouble installing xdebug at first because I was using the latest version of zend server… however, once that was all taken care of, the video was extremely helpful. Thanks!!
Great video, but I’m having the following problem:
I can use most assertion methods such as assertModule(), assertController(), assertAction() and assertResponseCode(), but when I try to use methods such as assertQueryContentContains() or assertXpathContentContains(), I get the following exception:
Zend_Dom_Exception: Error parsing document (type == docXml)
Has anyone else encountered this, or have clues as to how to fix?
Regards,
Ian
My error was due to having the following at the top of my response:
As my document was not in fact valid XML, removing this solved my problem.
Also see http://www.nabble.com/PHPUnit-testing-generating-Zend_Dom_Exception-td25522644.html
Regards,

Hi There,
for all who tries it with ZF 1.9.x and PHHUnit 3.3.17 or greater the following would help to solve some issues:
-> asserting Xpath only accept valid xpath e.g.
assertContentContains(“id(‘message’)”,”default”) becomes
$this->assertXpathContentContains(“//h2[@id='message']“,”default” );
and somehow even xdebug is set the logging doesn’t work on my mac

Thanks for the screen cast. I figured with the help of fw-general ML, how to test models and library classes without extending Zend_Test_PHPUnit_ControllerTestCase.
Fix the session related testing issues:
In tests/bootstrap.php have this line of code
require_once ‘Zend/Session.php’;
Zend_Session::$_unitTestEnabled = true;
In the tests/bootstrap.php script initialize and bootstrap your application.
$application = new Zend_Application(
APPLICATION_ENV,
APPLICATION_PATH . ‘/configs/application.ini’
);
$application->bootstrap();
Note, we are not running the application, just bootstrapping. Your model classes can now extend PHPUnit_Framework_TestCase instead of Zend_Test_PHPUnit_ControllerTestCase.
thanks for mentioning this sudheer!
After running the sudo ln -s command, phpunit is not moved to my home directory. Any ideas?
Hi, first of all, great screencast. However I have a problem, when I run my tests phpunit always fails when I have 2 or more tests (1 test is fine). I’ve tracked this down to the $application->bootstrap() call, basically the 2nd call causes phpunit to “break”, but I get no output, just a single “.” and then the test ends (I don’t even get the 1 test run etc. output). Do you have any idea why this is? If I limit the bootstrap() to only get called once then it works, but obviously I shouldn’t have to as you didn’t in your example. Thanks Karl.
Hi, great screencast.
I know that I need XDebug for Code Coverage. I downloaded this http://www.xdebug.org/files/php_xdebug-2.0.5-5.3-vc9-nts.dll and I am using Zend Server 4.0.5 for Windows Vista (32bit). I activated XDebug in php.ini and disabled Zend Optimizer+, Zend Debugger.
For testing I used the code frome screencast (downloaded).
Now my problem: phpunit says that I am using a wrong version of XDebug (VC9 instead of VC8), but there is no VC8 to download. And I can not find xdebug 2.1.0-dev for download, like in the screencast.
How can I solve the problem?
oh sorry, and I am using Zend Server for php 5.3
I had some trouble to debug why my logging was filing after the first unit test was run.
I was grabbing my logger instance from Zend_Registry.
Well, it seems that PHPUnit resets all global variables and class static variables between tests, hence the static variable Zend_Registry uses to reference its singelton instance was being destroyed.
To work-around that I had to add a declaration to my TestCase class:
protected $backupStaticAttributesBlacklist = array(
‘Zend_Registry’ => array(‘_registry’)
);
That ensures that values set in the Zend registry are available to all unit tests.
(obviously have to be careful if the code you’re testing interacts with the registry in any non-trivial way. Mine doesn’t).
Hi,
Just wanted to ask for a little help here..
Following the tutorial, I managed to work my way until the creation of ControllerTestCase. When I started testing on the command line( I’m using Windows Vista, Zend Framework ), the prompt seemed to be pausing for a second then it it displays nothing. I tried running the bootstrap.php( almost similar to the bootstrap file demonstrated here ) by php and saw that error is:
PHP Fatal Error: Cannot redeclare class phpunit_framework_testcase on line 117.
I guess that’s why the phpunit does not display anything — the ControllerTestCase that I use( the one extending the Zend_Test_PHPUnit_ControllerTestCase ) fails.
I’ve been searching for the same issue over the internet to no avail.
Thanks for you help..
Hi Jon,
I’ve checked and checked and I can’t find phpunit within MAMP. I just went through and upgraded MAMP to the latest 1.8.3 and went to the directory you use: /Applications/MAMP/bin/php5/bin While the other 6 files that you show in your video are there, phpunit is not. (The other six are pear, peardev, pecl, php, php-config, phpize)
Are you sure you didn’t install it separately first? Is it possible that it was in an older version of MAMP and has subsequently been removed?
Do you know how to run this via zend studio? It seems it only can execute phpunit files (not using the configuration).
If i run phpunit from the commandline it needs xdebug for code coverage, and that disables the debug function.
