phpunit断言-assertDirectoryIsReadable

发布时间：2021-10-01 23:22:35编辑：雪饮阅读（）

 assertDirectoryIsReadable用于断言一个目录是否存在并且可读。

DirectoryIsReadableTest.php：
<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class DirectoryIsReadableTest extends TestCase
{
    public function testFailure(): void
    {
        $this->assertDirectoryIsReadable('/path/to/directory');
    }
    public function testFailureRead(): void
    {
        $this->assertDirectoryIsReadable('/usr/local/a');
    }
}
运行结果：
[root@localhost local]# /usr/local/php734/bin/php /usr/local/phpunit-9.5.8.phar /usr/local/organizing/tests/DirectoryIsReadableTest.php
PHPUnit 9.5.8 by Sebastian Bergmann and contributors.

FAILURES!

这里实际上/path/to/directory目录是不存在的。
[root@localhost local]# ls /path/to/directory
ls: cannot access /path/to/directory: No such file or directory
而另外一个目录/usr/local/a虽然存在。
当时我设置了不可读的权限
[root@localhost local]# chmod 000 /usr/local/a
[root@localhost local]# ls -la /usr/local/a
total 4
d-wx-wx-wx   2 root root    6 Oct 1 10:59 .
drwxr-xr-x. 21 root root 4096 Oct 1 10:59 ..
但是从上面的结果来看，只有一个错误，实际上应该是两个错误，因为这个/usr/local/a这个目录被设置了不可读的权限。
因为官方文档https://phpunit.readthedocs.io/zh_CN/latest/assertions.html#assertclasshasstaticattribute
中有提到：
当 $directory 所指定的目录不是个目录或不可读时报告错误，错误讯息由 $message 指定。
或者是这里我堆这个不可读的理解不太对吧。
