php 单元测试

常用命令

新建一个单元测试

php artisan make:test ReplyTest --unit
单独执行某个测试

 phpunit tests/Unit/ReplyTest.php
单独执行某个测试中的函数

phpunit --filter a_thread_has_a_creator
带上测试环境变量进行测试就不需要 CsrfToken

APP_ENV=testing phpunit --filter an_authenticated_user_may_participate_in_forum_threads

APP_ENV=testing phpunit

测试类例子


class TestCase extends Illuminate\Foundation\Testing\TestCase {

	/**
	 * Creates the application.
	 *
	 * @return \Illuminate\Foundation\Application
	 */
	public function createApplication()
	{
		$app = require __DIR__.'/../bootstrap/app.php';

		$app->make('Illuminate\Contracts\Console\Kernel')->bootstrap();

		return $app;
	}

}
class FooTest extends TestCase {

    public function testSomethingIsTrue()
    {
        $this->assertTrue(true);
    }

}
你可以从终端机执行phpunit 命令来执行应用程序的所有测试。

$response = $this->call('GET', 'user/profile');

$response = $this->call($method, $uri, $parameters,  $cookies, $files, $server, $content);
接着你可以检查Illuminate\Http\Response 对象：

$this->assertEquals('Hello World', $response->getContent());
从测试调用控制器

你也可以从测试调用控制器：

$response = $this->action('GET', 'HomeController@index');

$response = $this->action('GET', 'UserController@profile', array('user' => 1));

phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="bootstrap/autoload.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false"
         syntaxCheck="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="SESSION_DRIVER" value="array"/>
        <env name="QUEUE_DRIVER" value="sync"/>
    </php>
</phpunit>

覆盖率

pecl install xdebug
php.ini 手动添加 zend_extension=xdebug.so
 php -m|grep xdebug

phpunit --coverage-html ./tests/report 来生成 html 报告

在 phpunit.xml 添加如下代码：
<filter>
        <!--这里配置了白名单，只有这里边的代码会被统计覆盖率-->
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./tests/Unit</directory>
        </whitelist>
    </filter>
<logging>
   <log type="coverage-html" target="./tests/report" charset="UTF-8"/>
</logging>
 然后直接执行 phpunit 即可。

测试demo

git clone https://github.com/sebastianbergmann/money.git
phpunit --configuration build/phpunit.xml
//或者如下执行方式也行
php build/tools/phpunit.phar --configuration build/phpunit.xml

hook

PHPUnit则为我们提供了全面的hook接口：

public static function setUpBeforeClass()/tearDownAfterClass()//测试类构建/解构时调用
protected function setUp()/tearDown()//测试方法执行前/后调用
protected function assertPreConditions()/assertPostConditions()//断言前/后调用
<?php
namespace Tests;

use App\Example;
use PHPUnit\Framework\TestCase as BaseTestCase;

class ExampleTest extends BaseTestCase
{
    // 类静态属性
    private static $example;

    public static function setUpBeforeClass()
    {
        self::$example = new Example();
    }

    public function testGetTrue()
    {
        // 类的静态属性更新
        self::$example->setMsg("hello big_cat");
        $result = self::$example->getTrue();
        $this->assertTrue($result);
    }

    public function testGetFalse()
    {
        $result = self::$example->getFalse();
        $this->assertFalse($result);
    }

    /**
     * 依赖 testGetTrue 执行完毕
     * @depends testGetTrue
     * @return [type] [description]
     */
    public function testGetMsg()
    {
        $result = self::$example->getMsg();
        $this->assertEquals($result, "hello big_cat");
    }
}
