Question

首先，我是PHPUnit测试和PHP的新手，对不起，如果我错过了太明显的东西。

好的，现在，对于我的问题：我正在使用名为ItemClickSupport.java的虚拟文件系统来测试函数VfsStream。出于某种原因，在我的测试中发生了这个错误：

我知道我的Unlink课程和它返回的内容是什么，但我不知道是什么。

我正在测试的课程：

[bianca@cr-22ncg22 tests-phpunit]$ phpunit
PHPUnit 4.6.10 by Sebastian Bergmann and contributors.

Configuration read from /var/www/html/tests-phpunit/phpunit.xml

E

Time: 27 ms, Memory: 4.50Mb

There was 1 error:

/home/bianca/.composer/vendor/phpunit/phpunit/src/TextUI/Command.php:105

FAILURES!
Tests: 1, Assertions: 0, Errors: 1.

我的测试所在的课程：

class Unlink {

    public function unlinkFile($file) {

        if (!unlink($file)) {
            echo ("Error deleting $file");
        }
        else {
            echo ("Deleted $file");
        }

        return unlink($file);
    }

}

?>

有人可以帮我解决吗？

你得到的错误是因为最初你创建了这个局部变量：

$removeFile = new Unlink();

但是当你这样做时，你会将其称为$this->$removeFile：

$this->$removeFile->unlinkFile(vfsStream::url('home/test.txt'));

这不正确;您可以使用具有类变量的地方，并且您想要动态引用它。 e.g。

class YourClass {
    public $foo;
    public $bar;

    public function __construct() {
        $this->foo = 'hello';
        $this->bar = 'world';
    }

    public function doStuff() {
        $someVariable = 'foo';

        echo $this->$someVariable;  // outputs 'hello'
    }
}

您需要做的就是摆脱$this，并将其更改为：

$removeFile->unlinkFile(vfsStream::url('home/test.txt'));
