发布时间：2021-10-02 19:47:14编辑：雪饮阅读（）

 assertFileExists断言用于断言一个文件是否存在，存在则断言为真。

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

final class FileExistsTest extends TestCase
{
    public function testFailure(): void
    {
        $this->assertFileExists('D:\phpstudy_pro\Extensions\php\php7.4.3nts\php.java');
    }
    public function testSuccess(): void
    {
        $this->assertFileExists('D:\phpstudy_pro\Extensions\php\php7.4.3nts\php.exe');
    }
}
运行结果如：
C:\Users\Administrator>D:\phpstudy_pro\Extensions\php\php7.4.3nts\php.exe C:\Users\Administrator\PhpstormProjects\untitled\vendor\phpunit\phpunit\phpunit -c C:\Users\Administrator\PhpstormProjects\untitled\organizing\phpunit.xml C:\Users\Administrator\PhpstormProjects\untitled\organizing\tests\FileExistsTest.php
