Question

PHPUnit和测试新手，并一直关注Teamtree House的指南。但是我在这一点上陷入困境，并想知道是否有人可以提供帮助。以下是我的文件中的详细信息：

phpunit.xml ---在root

<phpunit backupGlobals="true" bootstrap="tests/bootstrap.php">
  <!-- Blacklist the vendor folder -->
  <filter>
    <blacklist>
      <directory>vendor</directory>
    </blacklist>
  </filter>
  <!-- Add the main testsuite -->
  <testsuite>
    <directory>tests</directory>
  </testsuite>
</phpunit>

bootstrap.php --- in ./tests/bootstrap.php

<?php
// Get autoloader
require './vendor/autoload.php';

// Get tests
require './tests/PigLatinTest.php';

// Initialise twig
$loader = new Twig_Loader_Filesystem('./src');
$twig = new Twig_Environment($loader);

PigLatinTest.php --- in ./tests/PigLatinTest.php

<?php
require 'vendor/autoload.php';
require 'src/PigLatin.php';

class PigLatinTest extends PHPUnit\Framework\TestCase
{
  /**
   * @test PigLatin
   */
  public function englishToPigLatinWorksCorrectly()
  {
    /**
     * Given I have an english word
     * If I pass that word to my PigLatin converter
     * I get back the correctly transformed version
     */
     $word = 'test';
     $expectedResult = 'esttay';

     $pigLatin = new PigLatin();
     $result = $pigLatin->convert($word);

     $this->assertEquals(
        $expectedResult,
        $result,
        "PigLatin conversion did not work correctly"
     );
  }
}

PigLatin.php --- in ./src/PigLatin.php

<?php

class PigLatin
{
  public function convert($word)
  {
    // Remove first letter of the word
    $first_letter = substr($word, 0, 1);
    $new_word = substr($word, 1, strlen($word) - 1);
    $new_word .= $first_letter . 'ay';

    return $new_word;
  }
}

当我在终端中运行命令 phpunit 时，我得到以下输出：

PHPUnit 6.2.3 by Sebastian Bergmann and contributors.

Time: 68 ms, Memory: 10.00MB

No tests executed!

但是当我运行 phpunit PigLatinTest.php 时，我收到以下错误：

PHP Fatal error:  Uncaught PHPUnit\Runner\Exception: Class 'PigLatinTest' could not be found in 'PigLatinTest.php'. in phar:///usr/local/bin/phpunit/phpunit/Runner/StandardTestSuiteLoader.php:101

这让我很困惑，我根本找不到解决方案。如果有人有一些值得赞赏的见解！

您的问题与所有包含有关。他们试图包含错误的文件。

<强>测试/ bootstrap.php中

<?php
// Let's use absolute paths instead with the help of __DIR__ which
// will give us the path to the current folder.
require __DIR__ . '/../vendor/autoload.php'; // Up one folder where the vendor is

// Removed the include for PigLatinTest since PHPUnit will handle that.

// Again, let's use __DIR__ to solve the path issues.
$loader = new Twig_Loader_Filesystem(__DIR__ . '/../src');

$twig = new Twig_Environment($loader);

// If you're PigLatin-class isn't loaded with autoloading (in your composer.json),
// let's include it in here. Again, with the help of __DIR__
require __DIR__ . '/../src/PigLatin.php';

<强>测试/ PigLatinTest.php
在您的测试类中，我们可以删除所有include。引导程序已经处理好了。

<强>结论
重要的是要记住，如果您包含/要求包含/需要其他文件的文件，则所有相对路径将与执行包含的文件相关，而不是文件本身。最好的方法是：require __DIR__ . '/relative/from/this/file.php。魔术常量__DIR__为您提供了写入文件的绝对路径。

一旦将文件包含到项目中一次，其中的所有类和函数都可以在请求的其余部分中访问。不需要多次包含它。

PHPUnit类无法找到自己
