phpunit断言-assertFileIsWritable

发布时间：2021-10-02 21:26:40编辑：雪饮阅读（）

 assertFileIsWritable断言用来断言一个文件它是个文件并且可写。

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

final class FileIsWritableTest extends TestCase
{
    public function testFailure(): void
    {
        $this->assertFileIsWritable('/path/to/file');
    }
    public function testSuccess(): void
    {
        $this->assertFileIsWritable('/usr/local/file_w');
    }
}
先看我们的一个可写的文件：
[root@localhost ~]# ls -l /usr/local/file_w
-rwxrwxrwx 1 root root 0 Oct 2 09:22 /usr/local/file_w
然后我们看看运行结果：
[root@localhost ~]# /usr/local/php734/bin/php /usr/local/phpunit-9.5.8.phar /usr/local/organizing/tests/FileIsWritableTest.php
PHPUnit 9.5.8 by Sebastian Bergmann and contributors.
