使用本地PHP服务器模拟外部API的简单解决方案（无二进制依赖项）

专为PHPUnit设计，但您可以将其用于任何东西。

工作原理

每次调用ApiMocker::start时，都会启动一个新的本地PHP服务器（通过php -S）。

服务器从临时文件中读取其路由配置（URL、方法和相应的响应）。此文件在每次请求时都会重新读取，因此您可以在服务器启动后重新配置路由和响应。

此文件由php-http-mock软件包自动写入和创建，并通过环境变量传递给服务器。

示例

<?php

declare(strict_types=1);

namespace Test\Integration\App\HttpMock\Client;

use App\HttpMock\Client\ApiMocker;
use PHPUnit\Framework\TestCase;
use Symfony\Component\HttpClient\HttpClient;
use Symfony\Contracts\HttpClient\HttpClientInterface;

final class ApiMockerTest extends TestCase
{
    private ApiMocker $apiMocker;
    private HttpClientInterface $httpClient;

    protected function setUp(): void
    {
        $this->apiMocker = ApiMocker::create();
        $this->apiMocker->start();

        $this->httpClient = HttpClient::createForBaseUri($this->apiMocker->getBaseUri());
    }

    protected function tearDown(): void
    {
        $this->apiMocker->stop();
    }

    /**
     * @test
     */
    public function allowsDifferentResponsesOnTheSameUri(): void
    {
        $this->apiMocker->routeWillReturn('/expected-uri', responseCode: 400, responseBody: 'get response');
        $this->apiMocker->routeWillReturn('/expected-uri', 'POST', 500, 'post response');

        $getResponse = $this->httpClient->request('GET', '/expected-uri');
        $this->assertSame(400, $getResponse->getStatusCode());
        $this->assertSame('get response', $getResponse->getContent(false));

        $postResponse = $this->httpClient->request('POST', '/expected-uri');
        $this->assertSame(500, $postResponse->getStatusCode());
        $this->assertSame('post response', $postResponse->getContent(false));
    }

    /**
     * @test
     */
    public function returnsRequestsMadeToApiServer(): void
    {
        $this->apiMocker->routeWillReturn('/request?to=keep', 'POST');
        $this->httpClient->request('POST', '/request?to=keep', ['body' => 'expected-body']);

        $request = $this->apiMocker->lastRequestOn('/request?to=keep', 'POST');

        $this->assertSame('expected-body', $request->getContent());
    }
}
