SilverStripe蓝宝石单元测试抛出错误，当使用objFromFixture方法从灯具中检索对象时，“找不到对象”

Question

我正在从事SilverStripe项目。我现在正在尝试为我的应用程序编写单元测试和功能测试。在测试中，我使用Fixture文件将页面植入数据库。当我尝试为SilverStripe项目内置的Page类的固定装置播种时，就很好了。以下是我的代码。

class PageTest extends \SilverStripe\Dev\FunctionalTest
{
    protected static $fixture_file = 'fixtures.yml';

    public function testMyMethod()
    {
        $expectedURLs = [
            'new_page' => 'testing1',
            'old_page' => 'testing2',
        ];

        foreach ($expectedURLs as $fixture => $urlSegment) {
            $obj = $this->objFromFixture('Page', $fixture);

            $this->assertEquals($urlSegment, $obj->URLSegment);
        }
    }
}

这是我的灯具文件。

Page:
    new_page:
        Title: New Page 1
        Heading: Wellington
        PublishedDate: 2015-12-12 00:00:01
        ShowInFooterUsefulLinks: true
        PageTheme: Default
        URLSegment: testing1
    old_page:
        Title: Old Page 1
        Heading: Wellington 1
        PublishedDate: 2015-12-12 00:00:01
        ShowInFooterUsefulLinks: true
        PageTheme: Default
        URLSegment: testing2

以上测试正在按预期进行。

在测试中，我想改用EventPage类。我有一个叫做EventPage的类，它是从Page类扩展的。该EventPage类表具有一个额外的字段，称为EventDate。这样我将我的灯具文件修改为以下文件。

EventPage:
    new_page:
        Title: New Page 1
        Heading: Wellington
        PublishedDate: 2015-12-12 00:00:01
        ShowInFooterUsefulLinks: true
        PageTheme: Default
        URLSegment: testing1
        EventDate: 2015-12-12 00:00:01
    old_page:
        Title: Old Page 1
        Heading: Wellington 1
        PublishedDate: 2015-12-12 00:00:01
        ShowInFooterUsefulLinks: true
        PageTheme: Default
        URLSegment: testing2
        EventDate: 2015-12-12 00:00:01

这次我改用EventPage类。

我也为此修改了我的测试课程

class PageTest extends \SilverStripe\Dev\FunctionalTest
{
    protected static $fixture_file = 'fixtures.yml';

    public function testMyMethod()
    {
        $expectedURLs = [
            'new_page' => 'testing1',
            'old_page' => 'testing2',
        ];

        foreach ($expectedURLs as $fixture => $urlSegment) {
            $obj = $this->objFromFixture('EventPage', $fixture);

            $this->assertEquals($urlSegment, $obj->URLSegment);
        }
    }
}

运行测试时，出现以下错误。

我的考试有什么问题，我该如何解决？

读取错误消息：

Fatal error: Couldn't find object 'new_page' (class: Eventage)

[似乎在测试代码中有一个错字，其中Eventage应该为EventPage。
