Restler，为 POST 方法编写测试

Question

我想在 Behat 中为一个将对象作为输入的 POST 方法编写一个 TestScenario。

Feature: Testing The ChildController Endpoint

  Scenario: Trying to create an Child by POSTing vars with an existing Id
    Given that I want to make a new "Child"
    And the request is sent as JSON
    And its "screening_id" is "999888777666"
    And his "first_name" is "John"
    And his "last_name" is "Doe"
    And his "birth_date" is "1979-01-01"
    And his "gender" is "m"
    When I request "/v1/child"
    Then the response status code should be 409
    And the response should be JSON
    And the response has a "error" property

我的方法是这样的：

/**
 * Child Endpoint v1
 *
 * @url POST child/
 * @status 201
 *
 * @param Child $child JSON data 
 * @return application/json
 * @throws RestException
 */
function insertChild(Child $child){......}

我传递的 JSON 对象如下所示：

{
"child": {
    "screening_id": "",
    "first_name": "",
    "last_name": "",
    "birth_date": "",
    "gender": ""
}

}

现在...当我向 Postman 提出请求时，只有：

{
    "screening_id": "",
    "first_name": "",
    "last_name": "",
    "birth_date": "",
    "gender": ""
}

它工作正常。 但是当我运行 Behat 测试时，它说我为 'child' 指定了一个无效值，我得到：

"error": {
      "code": 400,
      "message": "Bad Request: Invalid value specified for 'child'. Expecting an item of type `v1\\models\\Child`"

}

它可以在任何地方工作，而无需仅从 BeHat 指定“孩子”。

解决方案是更改行为特征文件中的顺序

由于RestContext.php bootstrap file 的定义方式，它以这种方式工作。

目前你有什么和测试结果

Feature: Testing The ChildController Endpoint

  Scenario: Trying to create an Child by POSTing vars with an existing Id # features/test.feature:3
    Given that I want to make a new "Child"                               # RestContext::thatIWantToMakeANew()
    And the request is sent as JSON                                       # RestContext::theRequestIsSentAsJson()
    And its "screening_id" is "999888777666"                              # RestContext::thatItsStringPropertyIs()
    And his "first_name" is "John"                                        # RestContext::thatItsStringPropertyIs()
    And his "last_name" is "Doe"                                          # RestContext::thatItsStringPropertyIs()
    And his "birth_date" is "1979-01-01"                                  # RestContext::thatItsStringPropertyIs()
    And his "gender" is "m"                                               # RestContext::thatItsStringPropertyIs()
    When I request "/v1/child"                                            # RestContext::iRequest()

|  POST /behat_test/v1/child HTTP/1.1
|  Host: localhost
|  User-Agent: Guzzle/3.1.2 curl/7.43.0 PHP/5.6.15
|  Content-Type: application/json; charset=utf-8
|  Content-Length: 2
|  
|  []
|  HTTP/1.1 400 Bad Request
|  Date: Sun, 20 Dec 2015 04:21:56 GMT
|  Server: Apache/2.4.16 (Unix) PHP/5.5.30

|  {
|      "error": {
|          "code": 400,
|          "message": "Bad Request: Invalid value specified for `child`. Expecting an item of type `Child`"
|      },

如果你仔细观察，请求只发送一个空数组

|  POST /behat_test/v1/child HTTP/1.1
|  Host: localhost
|  User-Agent: Guzzle/3.1.2 curl/7.43.0 PHP/5.6.15
|  Content-Type: application/json; charset=utf-8
|  Content-Length: 2
|  
|  []

修复是将And the request is sent as JSON 移动到所有属性定义下方。见下文

    Given that I want to make a new "Child"                               # RestContext::thatIWantToMakeANew()
    And its "screening_id" is "999888777666"                              # RestContext::thatItsStringPropertyIs()
    And his "first_name" is "John"                                        # RestContext::thatItsStringPropertyIs()
    And his "last_name" is "Doe"                                          # RestContext::thatItsStringPropertyIs()

    And the request is sent as JSON                                       # RestContext::theRequestIsSentAsJson()
    When I request "/v1/child"                                            # RestContext::iRequest()
