用于 symfony2 中功能测试的 PHPUnit DataProvider

Question

我正在尝试对如下表单进行功能测试

//快乐场景

public function testRegisterActionInvalidCase($password, $confPassword, $gender, $country, $city, $schoo, $schoolName, $shortName, $keyWords, $expectedMessage) {
    $user = $this->_testUtilityService->getRandomEntity($this->_userService, 'FOS\UserBundle\Model\User');
    $token = $user->getConfirmationToken();
    $url = $this->generateUrl('teacher_register', array('token' => $token));
    $crawler = $this->client->request('POST', $url);
    $crawlerResponse = $this->client->getResponse();

    //[ASSERTIONS] Page is loaded ok
    $this->assertEquals(200, $crawlerResponse->getStatusCode());
    //[ASSERTIONS] that the loaded page is the correct one
    $this->assertContains($this->Translator->trans('Teacher Registration'), $this->client->getResponse()->getContent());
    $form = $crawler->selectButton('Save')->form();
    $confPassword = $password = $this->Faker->password();

    if ($gender === 'GENDER') {
        $gender = $this->Faker->randomElement([Gender::FEMALE, Gender::MALE]);
    }
    if ($gender === 'COUNTRY') {
        $country = $this->_testUtilityService->getRandomEntity($this->_countryService, '\ITJari\GeneralBundle\Entity\Country');
    }
    if ($gender === 'CITY') {
        $city = $this->_testUtilityService->getRandomEntity($this->_cityService, '\ITJari\GeneralBundle\Entity\City');
    }
    if ($gender === 'SCHOOL') {
        $schoo = $this->_testUtilityService->getRandomEntity($this->_schoolService, '\ITJari\SchoolBundle\Entity\School');
    }

    // fill in the form to be submitted
    $form["plainPassword['first']"] = $password;
    $form["plainPassword['second']"] = $confPassword;
    $form["gender"] = $gender;
    $form["country"] = $country;
    $form["city"] = $city;
    $form["school"] = $schoo;
    $form["school_name"] = $schoolName;
    $form["short_name"] = $shortName;
    $form["key_words"] = $keyWords;
    $crawler = $this->client->submit($form);
    //[ASSERTIONS] that the form submitted successfully
    $this->assertTrue($crawler->filter('html:contains("Teacher has been created successfully")')->count() > 0);
}

//大小写无效 我如何使用数据提供程序来测试功能测试的无效案例？ 这是我的尝试:

    $token = $user->getConfirmationToken();

但是我不知道如何将表单验证消息分配给使用数据提供者

Answer 1

请记住一些注意事项。

• 从不在单元测试期间调用返回随机数据的方法。因为这样可能会发生测试一次通过而另一次失败的情况。
• 不要生成 url，而是在测试中对其进行硬编码。我知道一开始感觉不对，但这实际上是你想做的事情。例如，如果您有一个公共(public) api 并且您“不小心”更改了 url，测试仍然可以工作，但是依赖该 api 的应用程序将停止工作。测试会警告您有关更改，然后您可以查看这是否真的是您想要的。

总的来说，这些测试对我来说看起来很复杂。我会把它分成 2 或 3 个测试。您可以在另一个测试中检查页面是否加载正常。此外，如果您需要 token 、用户或其他任何内容来进行身份验证，我建议您使用某种隐式登录方法。

数据提供者看起来像这样:

    /**
     * Test description
     * @dataProvider getSomeData
     * @param array $data
     */
    public function testSomething($data)
    {
        $test = $data['test'];
        ...
    }

    static function getSomeData()
    {
        return array(
            array('test' => 'a'),
            array('test' => 'b'),
            array('test' => 'c'),
        );
    }

如果你用 phpunit 做功能测试，没问题，但真的要考虑使用 behat。一旦你习惯了，它就容易多了。
