3、Tests
Symfony集成了PHPUnit作为测试框架。可以包含unit test、integration test和application test。
- 按照惯例，test目录下，应该复制一份与你应用目录相同的目录。
- 为了避免环境污染，每次的测试可以通过
bootKernel()的方式，reboot kernel。 - 可以通过
getContainer()来获取到ServiceContainer。 - DAMADoctrineTestBundle可以每次交互时，用的是未被修改的database
- application test一般在Controller目录下，作为request/response的处理
- 可以模拟客户端，
$crawler = $client->request('GET', '/post/hello-world');，来进行测试 - Client可以可以执行其他的操作，比如：
$crawler = $client->followRedirect(); $client->followRedirects(); $client->followRedirects(false); $client->loginUser($testUser, 'my_firewall') //登录 $client->xmlHttpRequest('POST', '/submit', ['name' => 'Fabien']); //ajax请求 $client->catchExceptions(false); //异常处理 $client->request('GET', '/post/hello-world'); $client->clickLink('Click here'); //模拟点击链接 $client->request('GET', '/post/hello-world'); $crawler = $client->submitForm('Add comment', [ 'comment_form[content]' => '...', ]); //模拟提交Form ... - 测试Response，验证输出符合预期。包括一系列的Assertion函数，比如：
assertResponseIsSuccessful(string $message = '', bool $verbose = true) Asserts that the response was successful (HTTP status is 2xx). assertResponseStatusCodeSame(int $expectedCode, string $message = '', bool $verbose = true) Asserts a specific HTTP status code. - 测试Request，验证输入符合预期。包括一系列的Assertion函数，比如
assertRequestAttributeValueSame(string $name, string $expectedValue, string $message = '') Asserts the given request attribute is set to the expected value. - 验证Browser，符合预期：
assertBrowserHasCookie(string $name, string $path = '/', ?string $domain = null, string $message = '')/assertBrowserNotHasCookie(string $name, string $path = '/', ?string $domain = null, string $message = '') - Crawler Assertions
assertSelectorExists(string $selector, string $message = '')/assertSelectorNotExists(string $selector, string $message = '') Asserts that the given selector does (not) match at least one element in the response. - Mailer Assertions
assertEmailCount(int $count, ?string $transport = null, string $message = '') Asserts that the expected number of emails was sent. - Notifier Assertions
assertNotificationCount(int $count, ?string $transportName = null, string $message = '') Asserts that the given number of notifications has been created (in total or for the given transport).
