Not able to call dependent test cases

I am writing the unit tests to test a Model class. First I have a testAddStudent() test case that adds some data to db. Then I have another test case to retrieve the record I just added. The code I have looks like the following:

class Model_STest extends PHPUnit_Framework_TestCase {

protected $_student;

public function setUp() {
    error_log("Entered setup");
    parent::setUp();

    $this->_student = new Application_Model_Student();
}

public function testInit() {
    error_log("Entered testInit");
}

public function testAddStudent() {
    error_log("Entered testAddStudent");
    $testData = array(
            'name' => 'abc',
            'teacher' => 'amyac',
            'start_date' => '2012_08_06'
            );

    $result = $this->_student->addStudent($testData);
    error_log("result is ".print_r($result, true));
    $this->assertGreaterThan(0, $result);
}

/**
 * @depends testAddStudent
 */
public function testGetStudent($result) {
    error_log("Entered testGetStudent, finding student id: $result");
    $resultx = $this->_student->getStudent($result);
    $this->assertEquals($result, $resultx);
    }

}

However, when I run the phpunit test (using command line), The logs show me that the student id being searched is 0. Whereas the testAddStudent is returning me the student id as a non-zero value.

What am I doing wrong? I have

PHPUnit 3.6.11 by Sebastian Bergmann.

Any help is greatly appreciated.

Thanks!

You should return $result from your testAddStudent() function.

(The returned value from the depended-on function is passed to depending function.)

You might also consider doing the same with your Application_Model_Student instance, instead of using a protected class variable. Here is your example rewritten to show that. (I used a dummy Application_Model_Student that does just enough to pass the test.)

class Application_Model_Student{
private $d;
function addStudent($d){$this->d=$d;return 1;}
function getStudent($ix){return $ix;}
}

//----------------------
class Model_STest extends PHPUnit_Framework_TestCase {

public function testAddStudent() {
    error_log("Entered testAddStudent");

    $testData = array(
            'name' => 'abc',
            'teacher' => 'amyac',
            'start_date' => '2012_08_06'
            );

    $student = new Application_Model_Student();
    $result = $student->addStudent($testData);
    error_log("result is ".print_r($result, true));
    $this->assertGreaterThan(0, $result);
    return array($student,$result);
}

/**
 * @depends testAddStudent
 */
public function testGetStudent($data) {
    list($student,$result)=$data;
    error_log("Entered testGetStudent, finding student id: $result");
    $resultx = $student->getStudent($result);
    $this->assertEquals($result, $resultx);
    }

}

P.S. Note the implementation I used for getStudent to get it to pass! I imagine this is not the test you intended to do.
