seeResponseMatchesJsonType does not work with null data #2522
Description
I read the documentation here and found that we can validate the types of JSON data returned with a REST webservice, and it seems to support null as a valid type :
// This is an example found here : http://codeception.com/docs/modules/REST
$I->seeResponseIsJsonType([
'user_id' => 'integer',
'name' => 'string|null',
'is_active' => 'boolean'
]);
However, using this in my tests, I get a failure when the data returned is null.
API returns :
{
"id": 123456,
"birthdate": null,
"firstname": "John",
"lastname": "Doe"
}
$I->seeResponseMatchesJsonType(array(
'birthdate' => 'string|null'
));
I get a failed test with this message :
Fail
birthdate: NULLis not of typestring|null
Can this be fixed, or is there a workaround ? Leaving only stringdoes not help. I can remove the check for the birthdate, but it is not an ideal solution.

seeResponseMatchesJsonTypeis pretty new feature so we plan to constantly improve it. Right now the best way to solve this issue is to help us make it better. Please send us a PR with a fix to it: https://github.com/Codeception/Codeception/blob/2.1/src/Codeception/Util/JsonType.phpIt would be even better if you include a failing test into https://github.com/Codeception/Codeception/blob/2.1/tests/unit/Codeception/Util/JsonTypeTest.php

On a side note, I managed to make it work by inverting the types.
string|nullfails my test, butnull|stringpasses.DavertMik commentedon Nov 12, 2015
Strange. I will try to reproduce and fix this issue

I didn't manage to reproduce it... Probably it depends on your PHP version. Which one are you using?

I see, that was fixed in #2500
