Phpunit unit test

1. Install ubuntu 12.04

wget https://phar.phpunit.de/phpunit.pharchmod +x phpunit.pharmv phpunit.phar /usr/local/bin/phpunit

2. Test Case phpunit1.php test dependency)

Demonstrate how to use @ depends annotation to express dependencies between test methods

<?phpclass StackTest extends PHPUnit_Framework_TestCase{    public function testEmpty()    {        $stack = array();        $this->assertEmpty($stack);                                                                                                                                     return $stack;    }                                                                                                                                 /**     * @depends testEmpty     */    public function testPush(array $stack)    {        array_push($stack, 'foo');        $this->assertEquals('foo', $stack[count($stack)-1]);        $this->assertNotEmpty($stack);                                                                                                                                     return $stack;    }                                                                                                                                 /**     * @depends testPush     */    public function testPop(array $stack)    {        $this->assertEquals('foo', array_pop($stack));        $this->assertEmpty($stack);    }}

4. to quickly locate defects, we hope to focus on relevant failure tests. This is why PHPUnit skips the test when the test on which a test depends fails. Through the dependency between tests, defect locating is improved.

The following example shows phpunit2.php:

<?phpclass DependencyFailureTest extends PHPUnit_Framework_TestCase{    public function testOne()    {        $this->assertTrue(FALSE);    }                                      /**     * @depends testOne     */    public function testTwo()    {    }}?>

5. Execution result

6. More than one @ depends annotation can be used for testing. PHPUnit does not change the test running sequence, so you need to ensure that all tests on which a test depends appear before this test.

There are multiple tests marked by @ depends. The first parameter is the basis provided by the first producer, the second parameter is the basis provided by the second producer, and so on.

Case study: phpunit3.php

<?phpclass MultipleDependenciesTest extends PHPUnit_Framework_TestCase{    public function testProducerFirst()    {        $this->assertTrue(true);        return 'first';    }             public function testProducerSecond()    {        $this->assertTrue(true);        return 'second';    }             /**     * @depends testProducerFirst     * @depends testProducerSecond     */    public function testConsumer()    {        $this->assertEquals(            array('first', 'second'),            func_get_args()        );    }}?>
