Mock_Response::getBody() 的返回值必须是 Psr\Http\Message\StreamInterface 的实例，在 PHPUnit 9.5.10 测试中返回的字符串

Question

我最近在我的 Symfony 4 应用程序中升级到 PHPUnit 9.5.10，现在我似乎有一堆与我使用 Guzzle 对端点进行的 HTTP 调用相关的失败测试。

失败的是：

1) Tests\AppBundle\Services\CourseTest::testUpdateAssignedCourseFromKey with data set "valid Course, current refkey" (AppBundle\Entity\Referral Object (...), array(true), AppBundle\Entity\Site Object (...), 'lambda')
TypeError: Return value of Mock_Response_0807f175::getBody() must be an instance of Psr\Http\Message\StreamInterface, string returned

/private/var/www/crmpicco/src/AppBundle/Services/Course.php:250
/private/var/www/crmpicco/src/AppBundle/Services/Course.php:187
/private/var/www/crmpicco/src/AppBundle/Services/Course.php:92
/private/var/www/crmpicco/Tests/AppBundle/Services/CourseTest.php:99

我的测试方法如下所示：

    /**
     * @dataProvider refkeyProvider
     *
     * @param Referral $referral
     * @param Site     $site
     * @param $expectedpartner
     *
     * @internal param Person $person
     */
    public function testUpdateAssignedCourseFromKey(Referral $referral, $apiresult, Site $site, $expectedCourse)
    {
        $apiresult = json_encode($apiresult);
        $response = $this->getMockBuilder('GuzzleHttp\Psr7\Response')->getMock();
        $response->expects($this->any())
            ->method('getBody')
            ->will($this->returnValue($apiresult));
        $client = $this->getMockBuilder('\GuzzleHttp\Client')->getMock();
        $client->expects($this->any())
            ->method('request')
            ->will($this->returnValue($response));

        $partner = new Course($this->username, $this->password, $client);
        $partner->setDoctrine($this->getDoctrine());

        $owner = $site->getOwner();
        $partner->updateAssignedCourseFromKey($site, $referral);

        $this->assertEquals($owner->getRefkey()->getRefkey(), $referral->getRefkey());
        $this->assertEquals($site->getRefkey()->getRefkey(), $referral->getRefkey());

        if (self::ANY_COURSE == $expectedcourse) {
            $this->assertNotEmpty($site->getOwner()->getCourseShortname());
        } else {
            $this->assertEquals($site->getOwner()->getCourseShortname(), $expectedcourse);
        }
    }

第 250 行是$data = json_decode($response->getBody());使用 Guzzle 进行 HTTP 调用的响应。

有我的解决方法。

use GuzzleHttp\Psr7\Stream;

$responseMock->expects($this->once())->method('getBody')->willReturn(new Stream(fopen('data://text/plain,' . $yourString,'r')));
