我正在尝试为我的小型框架应用程序编写一些PHPUnit测试,但是在文档中没有看到任何指向完整请求和断言响应的方法(包含文本或200状态,或任何事情,真的)。
有没有办法做到这一点,任何人都找到/使用过?

以下是测试Slim应用程序的示例:
https://github.com/mac2000/SlimTestable
假设我们有简单的应用程序:
<?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?
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,我们将所有路由移动到新的类构造函数,同时注意新的invoke
方法,它与run
方法相同,只是它返回响应而不是回显它。
现在您的index.php
文件可能就像这样:
<?php
require_once 'vendor/autoload.php';
$app = new App();
$app->run();
现在是时候进行测试了:
<?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', $response->headers()->get('Location'));
}
}
你应该注意到一些事情:
在设置测试时,我们正在创建$_SESSION
数组以用于测试目的,并实例化我们的App
类对象。
在测试而不是run
中,我们调用invoke
执行相同操作,但返回响应对象。
Environment::mock
用于模拟使用我们的应用程序处理的请求。

好的,所以我能够粗暴地让它变得有效。以下是端点测试类的示例。
假设您正在开发环境中工作,您可以对您自己的localhost执行curl
个请求,从而在提交回购之前进行测试。
首先,创建你的课程:
class ApiEndpointsTest extends PHPUnit_Framework_TestCase
{
protected $api_url = "http://localhost/api/v1";
//create a function that will allow you to call API endpoints at-will.
private function loadEndpoint($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
return array(
'body' => $output,
'info' => $info
);
}
//this allows you to write messages in the test output
private function printToConsole($statement) {
fwrite(STDOUT, $statement."\n");
}
使用它,您可以为特定的端点响应编写测试函数:
//this will test the actual body of the response against something expected.
public function testGetUserResponse() {
$this->printToConsole(__METHOD__);
$url = $this->api_url."/users/124";
$response = $this->loadEndpoint($url);
$expected = '[{"name":"John Smith","email":"john@acme.com"}]';
$this->assertEquals($response['body'], $expected);
}
在单独的测试中,您可以测试API调用响应的任何其他属性:
public function testGetUserMimeType() {
$this->printToConsole(__METHOD__);
$url = $this->api_url."/users/124";
$response = $this->loadEndpoint($url);
$this->assertEquals($response['info']['content_type'], 'application/json');
}
您可以在此处找到您的信息属性选项:http://php.net/manual/en/function.curl-getinfo.php
