Slim Framework端点单元测试 [英] Slim Framework endpoint unit testing

问题描述

我正在尝试为我的小型苗条框架应用程序编写一些PHPUnit测试，但在文档中找不到任何指向完整请求并在响应中断言(包含文本或200的方式)的方法.状态，或者其他任何东西).

I'm trying to write some PHPUnit tests for my small slim framework app, but don't see anywhere in the docs that point to a way to do a full request and assert on the response (either containing text or a 200 status, or anything, really).

有没有人发现/使用过的方法?

Is there any way to do this that anyone has found/used?

推荐答案

以下是示例您如何测试Slim应用程序的示例:

Here is example how you may test your Slim application:

https://github.com/mac2000/SlimTestable

假设我们有一个简单的应用程序:

Suppose we have simple application:

<?php
use Slim\Slim;

require_once 'vendor/autoload.php';

$app = new Slim();

$app->get('/', function(){
    echo 'home';
})->name('home');

$app->get('/hello/:name', function($name){
    echo "hello $name";
})->name('hello');

$app->map('/login', function() use($app) {
    if($app->request()->params('login')) {
        $app->flash('success', 'Successfully logged in');
        $app->redirect($app->urlFor('hello', array('name' => $app->request()->params('login'))));
    } else {
        $app->flash('error', 'Wrong login');
        $app->redirect($app->urlFor('home'));
    }
})->via('GET', 'POST');

$app->run();

我们如何测试它?

创建App类:

<?php // src/App.php
use Slim\Slim;

class App extends Slim {
    function __construct(array $userSettings = array())
    {
        parent::__construct($userSettings);

        $this->get('/', function(){
            echo 'home';
        })->name('home');

        $this->get('/hello/:name', function($name){
            echo "hello $name";
        })->name('hello');

        $this->map('/login', function() {
            if($this->request()->params('login')) {
                $this->flash('success', 'Successfully logged in');
                $this->redirect($this->urlFor('hello', array('name' => $this->request()->params('login'))));
            } else {
                $this->flash('error', 'Wrong login');
                $this->redirect($this->urlFor('home'));
            }
        })->via('GET', 'POST');
    }

    /**
     * @return \Slim\Http\Response
     */
    public function invoke() {
        $this->middleware[0]->call();
        $this->response()->finalize();
        return $this->response();
    }
}

请注意，我们将所有路由都移到了新的类构造函数中，还注意到了新的invoke方法，该方法与run方法相同，只是它返回响应而不是将其回显.

Notice that we move all our routes to new class constructor, also notice new invoke method, which do the same as run method except it returns response rather than echoing it out.

现在，您的index.php文件可能是这样的:

Now your index.php file might be like this one:

<?php
require_once 'vendor/autoload.php';

$app = new App();
$app->run();

现在是时候进行测试了:

And now it is time for tests:

<?php // tests/ExampleTest.php
use Slim\Environment;

class ExampleTest extends PHPUnit_Framework_TestCase {
    private $app;

    public function setUp()
    {
        $_SESSION = array();
        $this->app = new App();
    }

    public function testHome() {
        Environment::mock(array(
            'PATH_INFO' => '/'
        ));
        $response = $this->app->invoke();

        $this->assertContains('home', $response->getBody());
    }

    public function testHello() {
        Environment::mock(array(
            'PATH_INFO' => '/hello/world'
        ));
        $response = $this->app->invoke();

        $this->assertTrue($response->isOk());
        $this->assertContains('hello world', $response->getBody());
    }

    public function testNotFound() {
        Environment::mock(array(
            'PATH_INFO' => '/not-exists'
        ));
        $response = $this->app->invoke();

        $this->assertTrue($response->isNotFound());
    }

    public function testLogin() {
        Environment::mock(array(
            'PATH_INFO' => '/login'
        ));
        $response = $this->app->invoke();

        $this->assertTrue($response->isRedirect());
        $this->assertEquals('Wrong login', $_SESSION['slim.flash']['error']);
        $this->assertEquals('/', $response->headers()->get('Location'));
    }

    public function testPostLogin() {
        Environment::mock(array(
            'REQUEST_METHOD' => 'POST',
            'PATH_INFO' => '/login',
            'slim.input' => 'login=world'
        ));
        $response = $this->app->invoke();

        $this->assertTrue($response->isRedirect());
        $this->assertEquals('Successfully logged in', $_SESSION['slim.flash']['success']);
        $this->assertEquals('/hello/world', $response->headers()->get('Location'));
    }

    public function testGetLogin() {
        Environment::mock(array(
            'PATH_INFO' => '/login',
            'QUERY_STRING' => 'login=world'
        ));
        $response = $this->app->invoke();

        $this->assertTrue($response->isRedirect());
        $this->assertEquals('Successfully logged in', $_SESSION['slim.flash']['success']);
        $this->assertEquals('/hello/world', $response->headers()->get('Location'));
    }
}

您应该注意以下几点:

在设置测试的同时，我们出于测试目的创建$_SESSION数组并实例化App类对象.

While setting up test we are creating $_SESSION array for test purposes and instantiate our App class object.

在测试中，而不是在run中，我们正在调用invoke，它们执行相同的操作，但是返回响应对象.

In tests rather than run we are calling invoke which do the same, but returns response object.

Environment::mock用于模拟使用我们的应用程序处理的请求.

Environment::mock used to mock requests which are processed with our application.
