Question

我想在laravel中测试HTTP路由。 URL的动作函数调用帮助程序函数，该函数调用外部API。在测试过程中如何模拟外部API调用？

public function actionFunction(){

     $helper = new HelperClassHelper();

     return Response::json($helper->getNames());

}

在这里，getNames（）函数进行了外部API调用。我该如何模拟呢？

Answer 1

您可以在操作中将HelperClassHelper添加为依赖项，然后可以在测试中对其进行模拟：

public function actionFunction(HelperClassHelper $helper){
     return Response::json($helper->getNames());
}

在测试中：

$this->app->bind(HelperClassHelper::class, function () { /* return mock */ });

Answer 2

让我这么简单。

遵循此步骤：

1。）添加服务/srv。在这种情况下，我使用的是邮递员api。

app/Services/MyService/HttpClient.php

2。）添加控制器namespace App\Services\MyService; use GuzzleHttp\Client; use GuzzleHttp\Psr7\Response; class HttpClient { public function send(array $payload) : Response { return app(Client::class) ->request('POST', 'https://postman-echo.com/post', $payload); } }

app/Http/Controllers/TestController.php

3。）添加测试文件namespace App\Http\Controllers; use App\Services\MyService\HttpClient; use Illuminate\Http\Request; use Illuminate\Routing\Controller; class TestController extends Controller { public function index(Request $request) { $response = app(HttpClient::class)->send($request->toArray()); $data = json_decode( $response->getBody()->getContents(),true); return response()->json( $data, $response->getStatusCode() ); } }

tests/Feature/SampleTest.php

4。）添加json文件namespace Tests\Feature; use App\Services\MyService\HttpClient; use GuzzleHttp\Psr7\Response; use Illuminate\Support\Facades\File; use Tests\TestCase; class SampleTest extends TestCase { public function setUp(): void { parent::setUp(); //do awesome thing } public function testExample() { $this->mock(HttpClient::class, function ($mock) { return $mock->shouldReceive('send') ->once() ->andReturn(new Response( $status = 200, $headers = [], File::get(base_path('tests/files/success.json')) )); }); $data = [ 'mock' => 'no' ]; $response = $this->call('post','/test', $data); $response->assertExactJson(['mock' => 'yes']); $response->assertStatus(200); } }以获得虚假响应：

tests/files/success.json

在laravel 5中进行测试时，如何模拟外部API？
