PHPUnit-mockry:：mock vs mockry:：namedMocks

我正在用mockry编写PHPUnit测试（phpv5.6.32，PHPUnit 3.7.21，mockry dev master），发现了一些关于使用

mockry:：mock

和

mockry:：namedMocks

的不理解的地方

我的代码如下，问题如下：

我在LegendTest.php中使用信号收集对象的

mockry:：namedMock（）

而不是

mockry:：mock（）

是否正确

关于，我希望第一个参数是类名（

SignalsCollection

），第二个参数应该是extends语句（

\ArrayObject

）-但在我的例子中，我得到了一个错误：

mockry\Exception\BadMethodCallException:Received Charts\SignalsCollection:：getIterator（），但是没有指定期望值

，所以我只给出一个参数，这很好。为什么？我做错了什么？我很困惑

我是否错过了这个测试用例中的某些内容，或者我应该做一些不同的事情来改进测试

Signal.php：

class Signal
{
    protected $id = 0;
    protected $colName = '';
    protected $tableName = '';

    public function getId()
    {
        return $this->id;
    }

    public function setColName($colName)
    {
        $this->colName = $colName;

        return $this;
    }

    public function setTableName($tableName)
    {
        $this->tableName = $tableName;

        return $this;
    }
}

SignalsCollection.php：

class SignalsCollection extends \ArrayObject
{
}

Legend.php

class Legend
{
    protected $signalsCollection = null;
    protected $graphModel = null;

    public function __construct(SignalsCollection $signalsCollection, GraphModel $graphModel)
    {
        $this->signalsCollection = $signalsCollection;
        $this->graphModel = $graphModel;
    }

    public function getSignalsCollection()
    {
        return $this->signalsCollection;
    }

    public function removeSignal(Signal $signal)
    {
        foreach ($this->signalsCollection as $key => $item) {
            if ($item->getId() === $signal->getId()) {
                $this->signalsCollection->offsetUnset($key);
                break;
            }
        }
    }
}

LegendTest.php：

class LegendTest extends \PHPUnit_Framework_TestCase 
{
    protected function tearDown()
    {
        parent::tearDown();
        Mockery::close();
    }

    public function testRemoveSignal()
    {
        $testSignal = Mockery::mock('\Charts\Signal')
            ->shouldReceive('setColName', 'setTableName')
            ->andReturn(Mockery::self())
            ->mock();
        $testSignal
            ->setColName('testColumnName')
            ->setTableName('testTableName');

        $testSignalSecond = Mockery::mock('\Charts\Signal')
            ->shouldReceive('setId', 'setColName', 'setTableName')
            ->andReturn(Mockery::self())
            ->mock();
        $testSignalSecond
            ->setId(1)
            ->setColName('testColumnName')
            ->setTableName('testTableName');

        $signalsCollection = Mockery::namedMock('\Charts\SignalsCollection')
            ->shouldReceive('append', 'offsetUnset')
            ->andReturn(Mockery::self())
            ->mock();
        $signalsCollection
            ->append($testSignal)
            ->append($testSignalSecond);

        $legend = new Legend($signalsCollection, Mockery::mock('\Charts\GraphModel'));
        $this->assertEquals($signalsCollection, $legend->getSignalsCollection());

        $legend->removeSignal($testSignalSecond);
        $signalsCollection->offsetUnset(1);

        $this->assertEquals( $signalsCollection, $legend->getSignalsCollection() );
    }
}
