PHPUnit和全局变量 [英] PHPUnit and Globals

问题描述

我正在学习和探索PHPUnit与PHP 5.2.9的应用程序，并且遇到了globals问题.我已将$ backupGlobals设置为FALSE，并包含文档'@backupGlobals disabled'，但这似乎并不影响PHPUnit备份全局变量的行为.有什么我想念的吗?我需要更改PHPUnit的xml文件吗?创建引导程序?

I am learning and exploring applications of PHPUnit with PHP 5.2.9 and have run into the globals issue. I have set $backupGlobals to FALSE, included the doc '@backupGlobals disabled' and this doesn't seem to affect the behaviour of PHPUnit's backing up of the globals. Is there something I'm missing? Do I need to alter PHPUnit's xml file? Create a bootstrap?

config.php:

config.php:

$testString = 'Hello world!';

basicApp.php:

basicApp.php:

require ('D:\data\clients\security.ca\web_sites\QRASystems.com\wwwroot\__tests\BasicApp\config.php');

class BasicApp {

public $test;

public function __construct() {
    global $testString;
    $this->test = $testString;
}

public function getTest() {
    return $this->test;
}

public function setTest($test){
    $this->test = $test;
}

BasicAppTest.php:

BasicAppTest.php:

require ('D:\data\clients\security.ca\web_sites\QRASystems.com\wwwroot\__tests\BasicApp\BasicApp.php');

class BasicAppTest extends PHPUnit_Framework_TestCase{
    protected $testClass;
    protected $backupGlobals = FALSE;
    protected $backupGlobalsBlacklist = array('testString');

    public function SetUp(){
        $this->testClass = new BasicApp;
        $this->testClass->bootstrap();
    }

    public function testGlobal(){
        echo $this->testClass->getTest();
        $this->assertNotNull($this->backupGlobals);
        $this->assertFalse($this->backupGlobals);
        $this->assertNotEmpty($this->testClass->test);
    }

    public function testMethods(){
        $this->testClass->setTest('Goodbye World!');
        echo $this->testClass->getTest();
        $this->assertNotNull($this->backupGlobals);
        $this->assertNotNull($this->testClass->test);
        if (empty($this->testClass->test)) echo 'Method set failed!';
    }
}

testGlobal()在$ this-> assertNotEmpty($ this-> testClass-> test)上失败，表明$ this-> backupGlobals设置为FALSE，并且PHPUnit仍在备份全局变量.

testGlobal() fails on $this->assertNotEmpty($this->testClass->test), indicating that $this->backupGlobals is set to FALSE and that globals are still being back up by PHPUnit.

通过进行以下更改使我可以正常工作

I got this working by making the following changes-

BasicAppTest.php:

BasicAppTest.php:

    protected $backupGlobals = FALSE; <- REMOVED
    protected $backupGlobalsBlacklist = array('testString');  <- REMOVED

config.php:

config.php:

global $testString; <- ADDED
$testString = 'Hello world!';

我很震惊，这在某个地方还没有被掩盖过！

I am dumbfounded that this hasn't been covered before somewhere!

推荐答案

在您的测试用例中，您正在定义PHPUnit看不到的 new $backupGlobals属性.由于该属性是受保护的，因此可以在构造函数中将其设置为false，但是PHPUnit使用其构造函数来传递有关如何运行测试方法的信息.而是创建一个 phpunit.xml配置文件将backupGlobals属性设置为false.

In your test case you are defining a new $backupGlobals property that PHPUnit won't see. Since the property is protected, you could set it to false in the constructor, but PHPUnit uses its constructors to pass information on how to run the test method. Instead, create a phpunit.xml configuration file to set the backupGlobals property to false.

<phpunit backupGlobals="false">
    <testsuites>
        <testsuite name="Test">
            <directory>.</directory>
        </testsuite>
    </testsuites>
</phpunit>
