phpunit單元測試問題

Question

<?php 
namespace app\tests;

use PHPUnit\Framework\TestCase;
use GuzzleHttp\Client;

class UserTest extends TestCase
{
    private $client;

    public function setUp()
    {
        $this->client = new \GuzzleHttp\Client( [
            'base_uri' => 'http://z.slim.com',
            'http_errors' => false, 
        ]);
    }


    public function testUser()
    {
        $response = $this->client->get('/user/vilay');
        $this->assertEquals(200, $response->getStatusCode());
        $body = $response->getBody();
        $data = json_decode($body, true);
        $this->assertArrayHasKey('code', $data);
        $this->assertArrayHasKey('msg', $data);
        $this->assertArrayHasKey('data', $data);
        $this->assertEquals(0, $data['code']);
    }
}

寫完測試程式碼之後，執行

php vendor/bin/phpunit app/tests/UserTest.php

沒有執行到測試，直接把phpunit腳本輸出了

dir=$(d=${0%[/\]*}; cd "$d"; cd "../phpunit/phpunit" && pwd)

# See if we are running in Cygwin by checking for cygpath program
if command -v 'cygpath' >/dev/null 2>&1; then
    # Cygwin paths start with /cygdrive/ which will break windows PHP,
    # so we need to translate the dir path to windows format. However
    # we could be using cygwin PHP which does not require this, so we
    # test if the path to PHP starts with /cygdrive/ rather than /usr/bin
    if [[ $(which php) == /cygdrive/* ]]; then
        dir=$(cygpath -m "$dir");
    fi
fi

dir=$(echo $dir | sed 's/ /\ /g')
"${dir}/phpunit" "$@"

另外，我把單元測試配置到系統環境變數裡面，執行測試

phpunit app/tests/UserTest.php

需要在程式碼頭部引入autoload.php

#

require_once 'vendor/autoload.php';

沒辦法自動載入的嗎

Answer 1

已解決，在前面兩位朋友的答案提示下，自己找到了解決方法

網路找些教學很多都是用指令執行

php vendor/bin/phpunit tests.php

可能是因為版本原因，早期的版本是php腳本文件，我的版本是"phpunit/phpunit": "^6.2"，vendor/bin/phpunit是個shell腳本文件，（沒有用過5. x的具體我也不知道）。

正確使用方式是，給予腳本檔案可執行權限

chmod a+x vendor/bin/phpunit
chmod a+x vendor/phpunit/phpunit/phpunit

執行測試

sh vendor/bin/phpunit app/tests/UserTest.php

自動載入方式實作了，使用composer載入的phpunit元件包，在專案的根目錄中有個phpunit.xml,可以在裡面設定自動載入的路徑

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/5.7/phpunit.xsd"
         bootstrap="vendor/autoload.php"
         backupGlobals="false"
         beStrictAboutOutputDuringTests="true"
         beStrictAboutTestsThatDoNotTestAnything="true"
         beStrictAboutTodoAnnotatedTests="true"
         verbose="true">
    <testsuite>
        <directory suffix="Test.php">tests</directory>
    </testsuite>

    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">src</directory>
        </whitelist>
    </filter>

    <logging>
        <log type="coverage-html" target="build/coverage/html" title="phpDox"
             charset="UTF-8" highlight="true" lowUpperBound="60" highLowerBound="90"/>
    </logging>

</phpunit>

Answer 2

你可以在框架外，隨便寫一個單元測試文件，使用phpunit xxx.php 測試一下，這樣就知道是否phpunit安裝正常，是否引入autoload.php方式錯了,逐一排查。
