我可以使用PHPUnit模拟接口实现吗？

Posted 2021-04-30

我有一个我想要模拟的界面。我知道我可以模拟该接口的实现，但有没有办法只是模拟接口？

<?php
require __DIR__ . '/../vendor/autoload.php';

use MyHttpIClient as IHttpClient;  // The interface
use MySomethingElseClient as SomethingElseClient;


class SomethingElseClientTest extends PHPUnit_Framework_TestCase {
  public function testPost() {
    $url = 'some_url';
    $http_client = $this->getMockBuilder('CpmHttpIClient');
    $something_else = new SomethingElseClient($http_client, $url);
  }
}

我得到的是：

1) SomethingElseTest::testPost
Argument 1 passed to CpmSomethingElseClient::__construct() must be an instance of
MyHttpIClient, instance of PHPUnit_Framework_MockObject_MockBuilder given, called in
$PATH_TO_PHP_TEST_FILE on line $NUMBER and defined

有趣的是，PHPUnit, mocked interfaces, and instanceof会建议这可行。

答案

代替

$http_client = $this->getMockBuilder(CpmHttpIClient::class);

使用

$http_client = $this->getMock(CpmHttpIClient::class);

要么

$http_client = $this->getMockBuilder(CpmHttpIClient::class)->getMock();

完全有效！

另一答案

以下适用于我：

$myMockObj = $this->createMock(MyInterface::class);

另一答案

$http_client = $this->getMockBuilder(CpmHttpIClient::class)
                    ->setMockClassName('SomeClassName')
                    ->getMock();

在某些情况下，setMockClassName（）可用于解决此问题。
