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.
i want to start using phpunit for my web app and i am grateful for this video showing the basic steps. most of the pages in my app require the visitor to login . when i try to run any code via phpunit that is dispatching to the login page, i get error = ‘Zend_session is not marked as readable’.
here is my test method code:
public function testLoginActionPost()
{
$this->getRequest()
->setmethod(‘POST’);
$this->dispatch(“/auth/login”);
$this->assertController(“auth”);
$this->assertAction(“login”);
$this->assertResponseCode(200);
}
and here is the error:
There was 1 error:
1) IndexControllerTest::testLoginActionPost
Zend_Session_Exception: Zend_Session is not marked as readable.
library\Zend\Session\Abstract.php:86
library\Zend\Session\Namespace.php:391
library\Zend\Auth\Storage\Session.php:117
library\Zend\Auth.php:133
application\views\helpers\BuildMenu.php:13
library\Zend\View\Abstract.php:342
application\layouts\layout.phtml:11
library\Zend\View.php:108

library\Zend\Controller\Front.php:957
library\Zend\Test\PHPUnit\ControllerTestCase.php:190
tests\application\controllers\IndexControllerTest.php:45
if i follow the code in my BuildMenu.php, it is merely truying to check
if the user is logged in, when the exception is thrown:
$auth = Zend_Auth::getInstance();
if ($auth->hasIdentity()) { <——— this line causes Zend_Session_Exception: Zend_Session is not marked as readable.
to be thrown.
for melissa (and maybe others), i had a similar issue and got answered in stackoverflow: http://stackoverflow.com/questions/1808148/unit-testing-phpunit-how-to-login
i hope it helps.
cheers
sorry for double posting, i forgot to check the followup notify checkbox…
Hi,
My architecture is quite similar than yours, my problem is after adding that line of code in my ControllerTestCase.php file :
“$this->application->bootstrap();”
I still get the following error : “Zend_Controller_Exception: No default module defined for this application”
except for this simple test :”$this->assertTrue(TRUE);”
Any idea ?
Thanks,
Hi Mike,
I would double-check your application.ini file.
@paul (late but for others who find this via Google as I did)
There doesn’t seem to be a solution for using Xdebug with Zend Server CE 4.0.5. The “official” response is:
“The PHP project only supports VC6 and VC9, and not VC8. Therefore I only
have VC6 and VC9 versions for Xdebug. ”
Source: http://xdebug.org/archives/xdebug-general/1634.html
Thank you very much! Very helpful!! Thanks to your info I managed to add a phpunit to my current project all together with code coverage reports!
So I’ve been trying to follow with this, and I’ve gotten to about minute 21:35. phpunit seems to be running fine, but when i enter in $phpunit –configuration phpunit.xml, it’s doing nothing. it’s just giving me a new command line.
if i add die(‘i’m the bootstrap’) to tests/application/bootstrap.php at the beginning, phpunit is still outputting ‘i’m the bootstrap’
if i insert that die in any of the other methods that have been created to this point in the video, i get nothing as well, so it’s making it really hard to figure out what’s happening.
any suggestions?
Re: Ty Barho
I am having the same issue. It looks like PHPUnit is failing because it can not require the correct resources from Zend_Test_PHPUnit_ControllerTestCase.
It is requiring PHPUnit/Framework/TestCase.php among others.
Because my PHPUnit is installed in:
C:\Program Files\Zend\ZendServer\bin\PEAR\PHPUnit
The required classes are not on the include path.
I have messed about moving the files and changing the include_path but i have not yet got it to work.
PHPUnit is not outputting any Error messages to the CLI (is this Correct?) It just fails to require the needed resource and returns back to the prompt.

A follow up to the issues that I was having in my previous post.
My System
Zend Server CE 4.0.6
Windows XP
In tests/application/bootstrap.php
add
require_once ‘Zend/Test/PHPUnit/ControllerTestCase.php’;
Im not sure how Jon is loading this but somehow the include path to Zend doesn’t seem to work when running tests on the CLI. (maybe its just me?)
Code Coverage Reports
———————
In order to get the code coverage reports working, I needed to disable zend debugger (I did this via the Zend Server (http://localhost/ZendServer))
Then install xdebug. and worked through the following page which worked 1st time. (I ommitted Step 3 as i didnt have that line in the debugger.ini file
http://forums.zend.com/viewtopic.php?f=8&t=553
I Hope this saves somebody some time, as i have been working on this for way—tooooo–long.
Alex
I’m using Zend Server CE ver 5 (php 5.3.1) on Windows.
As you know, it comnes with Zend Debugger.
For some reason I ignore, phpunit was not working until I removed Zend Debugger and installed Xdebug:
xdebug-2.0.5-5.3-nts-Win32-VC9-x86.dll
I tried xdebug 2.1 with no luck.
Errata:
AS you can see, in minute 18:56, Jon included the line:
require_once ‘Zend/Test/PHPUnit/ControllerTestCase.php’;
But he never mentioned that on the video.
This was giving me a headache until I watched closely and found this issue.
Thanks Jon.
Thank you very much for the time you spent on this video. This does leave one question though and that is how do you test your library files?
For instance if you have
/library/Namespace/Controller/Plugin/MyFront.php
How could you then run tests against things like this? We have a library that consists of many files and I would not want to leave them out of the testing phase.
I have gotten this testing to work outside of Zend Studio but it would be really nice if I could get it to work inside Zend Studio. I also have not followed your video to get the tests working. I plan to go through your video again today or tomorrow and try to implement this and see if it will work for us. I am sure that if we can test our libraries as well as the controllers and models we would be able to adopt this practice.
Except this walkthrough doesn’t match the source, doesn’t work right with *.16 of phpunit, and refuses to call in my StatsTest model (die statement isn’t triggered for a check)
This really needs to be re-done, and actually have the source made in the video be the source online. Doesn’t work? Fix it in the video, don’t upload different source code.
For an abstract idea such as this, having everything 1:1 is necessary, when the video != source code posted, users like myself just can’t get anything to work.
Hi Peter,
I’ll be revisiting the Unit Testing stuff again, especially since MAMP no longer comes with phpunit out of the box. Thanks for the feedback!
Hi Joseph,
to be honest, I gave up on getting Zend_Test to work with Zend Studio 6 months ago and haven’t looked at it since. I prefer NetBeans’ implementation however I ultimately find myself back at the command line at the end of the day. I think we’ll need another year or two to see the IDE’s provide a complete TDD workflow for developers that’s smooth. You should still be able to test your Controller plugins, just initialize an instance of Zend_Controller (if needed) and inject the object your testing inside. I would also suggest reviewing how the Controller plugins that come out of the box are unit tested and see what can be done for your own library.
Jon,
I was not specifically talking about Zend_Test. You can use PHPUnit with Zend Studio and the Zend Framework without using Zend_Test. I have had the unit testing *kinda* working in Zend Studio I believe you just have to follow a specific method.
Jon,
Thank you very much for this video. It enabled me to implement testing of my ZF app and my external libraries. While I cannot do the testing directly in Zend Studio I am satisfied with the ability to test my controllers/models, etc.
Thanks Again!
Hi,
Code coverage is not generated. I have downloaded xdebug and configured php.ini file, but still code coverage is not generated. What could be the reason.
Please help.
Thanks in advance
@Karthik I was having that problem. The thing was that I has two php.ini files, one for apache (used when we are in a web context) and the other inside the php folder (user when we are running in command line mode). I realiced the php.ini I have to edit was the second in order to get code coverage.
This is great, however, I’ve ran into an issue when using resource plugins in Zend_Application, eg:
resources.cachemanager.database.frontend.name = Core
resources.cachemanager.database.frontend.options.caching = true
resources.cachemanager.database.frontend.options.lifetime = 300
resources.cachemanager.database.frontend.options.automatic_serialization = true
resources.cachemanager.database.backend.name = File
resources.cachemanager.database.backend.options.cache_dir = APPLICATION_ROOT “/data/cache”
It does not appear as if the resource plugins are being loaded because in my model that I am testing, I receive the following:
Fatal error: Call to a member function getResource() on a non-object in /path/to/my/app/application/models/MyModel.php on line 34
The line throwing the error is in the Model’s constructor when instantiating the cache from the resource plugin:
$this->cache = Zend_Controller_Front::getInstance()->getParam(‘bootstrap’)->getResource(‘CacheManager’)->getCache(‘database’);
Any ideas on how to set up tests with Resource Plugins?
Hey Jon,
Man, I’m having the same problema as Mike up there….and my structure is almost like yours.
This is it:
“Zend_Controller_Exception: No default module defined for this application”
Cmon, i’m not even using moules! lol
It happens by the time when my test function calls dispatch.
Any idea?
Thanks man!
Hey!
@Küpper: ran into the same problem, make sure your application.ini/configuration is loaded. I’m using modules, but probably this will help you nonetheless.
I’ve also problems with application resources. The plugin files are loaded (tested with a simple echo in that file), but their init method isn’t executed, therefore I’m not able to use the plugins. I’ve already made sure that my application.ini is loaded and contains the necessary configurations for that plugin.
Any help would be appreciated.
Okay, I found the problem.
It’s a little more complicated, short version:
One resource plugin fired an exception, the exception tried to access a resource which wasn’t loaded at that time. That caused an exception which said the resource isn’t loaded yet.
Maybe this will help someone.
Thanks for video. It’s good tutorial.
We are not getting log folder in Testing->tests. we are using windows prompt. So can you say the commands for how to create the log folder in tests…Can you help me………
if you change into the directory with the phpunit.xml (usually [project]/tests) and simply run `phpunit` it detects the phpunit.xml and uses the settings. just define the log options like in the video.
if this doesn’t work for you try
`phpunit –coverage-html “./log/report” –testdox-html “./log/testdox.html”`
a detailed description of how to invoke phpunit can be found here:
