Restler, writing test in behat for POST-Method - behat

Question

I want to write a TestScenario in Behat for a POST Method that takes an Object as input.
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
My Method is like:
/**
* Child Endpoint v1
*
* #url POST child/
* #status 201
*
* #param Child $child JSON data
* #return application/json
* #throws RestException
*/
function insertChild(Child $child){......}
My JSON Object that I pass looks like this:
{
"child": {
"screening_id": "",
"first_name": "",
"last_name": "",
"birth_date": "",
"gender": ""
}
}
Now... when I make a request with Postman with only:
{
"screening_id": "",
"first_name": "",
"last_name": "",
"birth_date": "",
"gender": ""
}
it works fine.
But when I'm running the Behat Test, it says that I specified an invalid value for 'child' and I get:
"error": {
"code": 400,
"message": "Bad Request: Invalid value specified for 'child'. Expecting an item of type `v1\\models\\Child`"
}
It works from everywhere without specifying the 'child' only from BeHat not.

Solution is to change the order of things in your behat feature file
It works this way because of the way RestContext.php bootstrap file is defined.
Currently what you have and the test result
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

| {
| "error": {

| "message": "Bad Request: Invalid value specified for `child`. Expecting an item of type `Child`"
| },
If you look closely the request is sending only an empty array
| 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
|
| []
Fix is to move And the request is sent as JSON below all property definitions. See below
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 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()
And the request is sent as JSON # RestContext::theRequestIsSentAsJson()
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: 108
