Restler，用POST方法编写测试方法

Question

我想在Behat中为一个以Object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

我的方法就像：

/**
 * 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My 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“孩子”指定了无效值。我得到了：

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

}

它可以在任何地方使用，而无需指定“孩子”。只有BeHat没有。
