Organizing phpunit function points_PHP tutorial

Set the scene

Create array Fixtures

[php]

protected function setUp()

{

//Create array fixture.

$this->fixture = array();

}

"Kit-level assembler" shared fixture is sharedFixture

The $sharedFixture attribute of the PHPUnit_Framework_TestSuite object is available in both the PHPUnit_Framework_TestSuite object collection and the PHPUnit_Framework_TestCase object.

[php]

protected function setUp()

{

$this->sharedFixture = new PDO(

'mysql:host=wopr;dbname=test',

'root',

''

);

}

Organizing test suites

The PHPUnit_Framework_TestSuite class of the PHPUnit framework allows us to organize some tests in a hierarchical structure composed of several test suites. Let's look at the PHPUnit-specific test suite through an example.

Example 7.1 shows a truncated version of Tests/AllTests.php, and Example 7.2 shows a truncated version of Tests/Framework/AllTests.php.

Level 1:

[php]

if (!defined('PHPUnit_MAIN_METHOD')) {

define('PHPUnit_MAIN_METHOD', 'AllTests::main');

}

require_once 'PHPUnit/Framework.php';

require_once 'PHPUnit/TextUI/TestRunner.php';

require_once 'Framework/AllTests.php';

// ...

class AllTests

{

public static function main()

{

PHPUnit_TextUI_TestRunner::run(self::suite());

}

public static function suite()

{

$suite = new PHPUnit_Framework_TestSuite('PHPUnit');

$suite->addTest(Framework_AllTests::suite());

// ...

return $suite;

}

}

if (PHPUnit_MAIN_METHOD == 'AllTests::main') {

AllTests::main();

}

?>

Level 2:

[php]

if (!defined('PHPUnit_MAIN_METHOD')) {

define('PHPUnit_MAIN_METHOD', 'Framework_AllTests::main');

}

require_once 'PHPUnit/Framework.php';

require_once 'PHPUnit/TextUI/TestRunner.php';

require_once 'Framework/AssertTest.php';

// ...

class Framework_AllTests

{

public static function main()

{

PHPUnit_TextUI_TestRunner::run(self::suite());

}

public static function suite()

{

$suite = new PHPUnit_Framework_TestSuite('PHPUnit Framework');

$suite->addTestSuite('Framework_AssertTest');

// ...

return $suite;

}

}

if (PHPUnit_MAIN_METHOD == 'Framework_AllTests::main') {

Framework_AllTests::main();

}

?>

Level 3:

[php]

/**

* PHPunit test suite

* /tests/Framework/Framework/AssertTest.php

* @anthor Chen Wei Han

* @copyright 2011-7-6 02:10:29 pm

* @package phpunit

* @todo

*/

//require_once 'PHPUnit/Framework.php';

class Framework_Framework_AssertTest extends PHPUnit_Framework_TestCase{

public function testNewArrayIsEmpty()

{

// Create array fixture.        

$fixture = array();                                        

// Assert that the size of the array fixture is 0.        

$this->assertEquals(0, sizeof($fixture));

}

public function testArrayContainsAnElement()

{

// Create array fixture.        

$fixture = array();                                        

// Add an element to the array fixture.        

$fixture[] = 'Element';

//Assert that the size of the array fixture is 1.        

$this->assertEquals(1, sizeof($fixture));

}

}

?>

Class Framework_AssertTest is a standard test case that extends PHPUnit_Framework_TestCase.

Running Tests/AllTests.php will use the TextUI test launcher to run all tests, while running Tests/Framework/AllTests.php will only run tests of class PHPUnit_Framework_*.

Kit level assembler

Class PHPUnit_Framework_TestSuite provides two template methods, setUp() and tearDown(), which are called before the first test and after the last test of the test suite respectively.

[php]

require_once 'MyTest.php';

class MySuite extends PHPUnit_Framework_TestSuite

{

public static function suite()

{

return new MySuite('MyTest');

}

protected function setUp()

{

print "nMySuite::setUp()";

}

protected function tearDown()

{

print "nMySuite::tearDown()";

}

}

?>

Incomplete and skipped tests

public function testSomething()

{

}

If we separate successful tests and failed tests as green and red lights, we also need a yellow light to mark unfinished or unimplemented tests. PHPUnit_Framework_IncompleteTest is a marking interface used to mark exceptions raised when the test result is incomplete or not currently implemented.

[php]

require_once 'PHPUnit/Framework.php';

class SampleTest extends PHPUnit_Framework_TestCase

{

public function testSomething()

{

//Optional: You can test anything.

$this->assertTrue(TRUE, 'This should already work.');

// Stop here and mark the test as incomplete.

$this->markTestIncomplete(

'This test has not been implemented yet.'

);

}

}

?>

Skipped test

Not all tests may run in a specific environment. Consider an example of a database extraction layer with multiple drivers to support different database systems. MySQL driven tests can of course only be run on a MySQL server. $this->markTestSkipped

[php]

require_once 'PHPUnit/Framework.php';

class DatabaseTest extends PHPUnit_Framework_TestCase

{

protected function setUp()

{

if (!extension_loaded('mysqli')) {

$this->markTestSkipped(

'The MySQLi extension is not available.'

);

} }

}

public function testConnection()

{

// ...

}

}

?>

PHPUnit_Framework_TestResult

When you are running all these tests, you need to store all the results somewhere: how many tests were run, which ones failed, and how long they took.

PHPUnit comes with two specific test decorators: PHPUnit_Extensions_RepeatedTest and PHPUnit_Extensions_TestSetup. The former is used to run a test repeatedly and only count as successful if all iterations succeed. The latter one is discussed in Chapter 6.

To customize PHPUnit_Framework_TestResult, there is no need to write its entire subclass. Most of the time, it is enough to implement a new PHPUnit_Framework_TestListener (see Table 22.14) and attach it to the PHPUnit_Framework_TestResult object before running the test.

Example 23.4: Running and observing a test suite

[php] www.2cto.com

require_once 'PHPUnit/Framework.php';

require_once 'ArrayTest.php';

require_once 'SimpleTestListener.php';

// Create a test suite including tests from class ArrayTest.

$suite = new PHPUnit_Framework_TestSuite('ArrayTest');

// Create a test result and attach a SimpleTestListener object as an observer to it.

$result = new PHPUnit_Framework_TestResult;

$result->addListener(new SimpleTestListener);

// Run the test.

$suite->run($result);

?>
