PHPUnit 和 Globals

2022-01-25 00:00:00 globals php phpunit

我正在使用 PHP 5.2.9 学习和探索 PHPUnit 的应用程序，并且遇到了全局问题.我已将 $backupGlobals 设置为 FALSE，包括文档@backupGlobals disabled"，这似乎不会影响 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:dataclientssecurity.caweb_sitesQRASystems.comwwwroot\__testsBasicAppconfig.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:dataclientssecurity.caweb_sitesQRASystems.comwwwroot\__testsBasicAppBasicApp.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，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.

我通过进行以下更改来完成这项工作-

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!';

我惊呆了，这在以前没有被报道过！

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

推荐答案

在你的测试用例中，你定义了一个 PHPUnit 看不到的 new $backupGlobals 属性.由于该属性受到保护，您可以在构造函数中将其设置为 false，但 PHPUnit 使用其构造函数来传递有关如何运行测试方法的信息.相反，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>
