Pointers to write unit test cases using EcomDev_PHPUnit

Question

I am trying to implement a web service client for one of my module and I would like to test it using EcomDev_PHPUnit. So, I have a "Test" folder inside my module with following structure...

- Webservice
-- Clientservice
---Model
----Callservice.php
--- Test
----Model
-----Callservice.php

My "Callservice.php" has a "httpRequest()" function that does Mage::log("Hello world!"); And as I am testing a service, I don't need any fixtures as of now...

But when I try to run "phpunit UnitTests.php"...I see a series of errors.The first few lines are about EcomDev_PHPUnitTest module I think we can ignore it safely. The other errors says that

Warning
There is no module with name: webservice_clientservice

My config.xml top most few lines are as follows,

<?xml version="1.0" encoding="UTF-8"?>
 <config>
    <modules>
        <Webservice_Clientservice>
            <version>0.1.0</version>
        </Webservice_Clientservice>
    </modules>
  ...
  ...
 <phpunit>
    <suite>
        <modules>
             <Webservice_Clientservice />
        </modules>
        <groups>
            <model>Model</model>
        </groups>
    </suite>
 </phpunit>
 </config>

My module xml file is Webservice_Clientservice.xml as follows,

<?xml version="1.0" encoding="UTF-8"?>
 <config>
    <modules>
        <Webservice_Clientservice>
            <active>true</active>
            <codePool>community</codePool>
            <depends>

            </depends>
        </Webservice_Clientservice>
    </modules>
 </config>

And when I use phpunit --filter <> UnitTests.php, I see the below -

PHPUnit 3.7.22 by Sebastian Bergmann.

No tests executed!

That leaves me perfectly confused. How do I write test cases(without test suites and later with test suites) in EcomDev_PHPUnit? Any pointers or same modules would be really great. Thanks!

Well it worked with the following:

I had missed a file "phpunit.xml.dist" in the magento root directory, not just that. I had to comment out a few lines in UnitTests.php in the magento root directory too - after which it looks as below -

<?php

//bootstrap.php already does this, not sure why we would need it here again
/*require 'app/Mage.php';

if (version_compare(PHP_VERSION, '5.3', '<')) {
    exit('Magento Unit Tests can be runned only on PHP version over 5.3');
}

if (!Mage::isInstalled()) {
    exit('Magento Unit Tests can be runned only on installed version');
}

$_SERVER['SCRIPT_NAME'] = dirname(__FILE__) . DS . 'index.php';
$_SERVER['SCRIPT_FILENAME'] = dirname(__FILE__) . DS . 'index.php';

Mage::app('admin');
Mage::getConfig()->init();*/

class UnitTests extends EcomDev_PHPUnit_Test_Suite
{

}

so now I see the log entry in mage system.log :)

Well, I am not yet sure if this is the right way...comments welcome

I suggest you read the documentation of the module which can be found here

http://www.ecomdev.org/wp-content/uploads/2011/05/EcomDev_PHPUnit-0.2.0-Manual.pdf

Anyway, to answer your question, your configuration is not correct. In your config.xml you should tell EcomDev_PHPUnit about your module, like this:

<config>
    ...
    <phpunit>
        <suite>
            <modules>
                <Webservice_Clientservice />
            </modules>
        </suite>
    </phpunit>
    ...
</config>

Now you can run your tests by calling

phpunit --group Webservice_Clientservice
