PHPUnit 错误 "Failed to open stream: No such file or directory"

Question

我刚刚安装了 PHPUnit Testing，但出于某种原因它无法读取我的文件。我确定它在正确的路径中，但为什么 PHPUnit 找不到它？

这是我的示例代码：

functions.php

<?php 

 function my_addition($arg1, $arg2){
        return $arg1 + $arg2;

 ?>

这是要测试的代码和文件：

functions_test.php

<?php 


use PHPUnit\Framework\TestCase;




class functions_test extends TestCase {


public function testmy_addition() {
    include("./data/functions.php");
    $result = my_addition(1,1);
    $this->assertEquals(2, $result);

}


}


?>

我该怎么做才能让它生效并通过？

Answer 1

您应该可以在包含语句中使用 __DIR__ . "/data/functions.php"
（也就是前后两个下划线）

我在我的测试环境中做了一个快速测试，没有任何问题。

__DIR__ 魔法常量为您提供了运行测试文件的完整路径。来自 PHP 网站：

The directory of the file. If used inside an include, the directory of the included file is returned. This is equivalent to dirname(__FILE__). This directory name does not have a trailing slash unless it is the root directory.
