PHPUnit DataProvider用於symfony2中的功能測試

Question

我正在嘗試對表單進行功能測試，如下所示

//快樂的場景

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);
}

//無效案例如何使用數據提供程序測試無效案例進行功能測試？ 這是我的嘗試：

 /** 
 * @dataProvider provideDataForRegistrationActionInvalidCase
 * @assertions Assert for exception asserted on "exception message"
 * 
 */
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;

}

但是我不知道如何將表單驗證消息分配給使用數據提供程序

Answer 1

請記住一些注意事項。

• 從不在單元測試期間調用返回隨機數據的方法。 因為這種方式可能會發生測試通過一次，然后再次失敗。
• 不要生成網址，而是在測試中對它們進行硬編碼。 我知道一開始感覺不對，但這實際上是你想做的事情。 例如，如果您有一個公共API，並且“意外地”更改了網址，則測試仍然有效，但依賴於api的應用程序將停止工作。 測試將警告您有關更改，然后您可以看到這是否真的是您想要的。

一般來說，測試看起來很復雜。 我會把它分成2或3個測試。 您可以在另一個測試中檢查頁面是否正常加載。 另外，如果您需要令牌，用戶或其他任何身份驗證，我建議您制作某種隱式登錄方法。

數據提供者看起來像這樣：

    /**
     * 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進行功能測試，那很好，但是真的考慮使用behat。 一旦你習慣了，它就容易多了。
