Community chat ? about godog

it is simple to debug it, since you have two slices of bytes to compare, assert the length first, then loop through every byte and compare it, if it does not match you can print the sequence of bytes [:i] as string in order to know where it did not match exactly. The issue in general does not relate to godog, that is all about your step definitions, you should not question such issues here, but rather on stackoverflow since it does not relate to godog

func (a *apiFeature) theResponseShouldMatchJSON(body *gherkin.DocString) (err error) {
	var expected, actual []byte
	var data interface{}
	if err = json.Unmarshal([]byte(body.Content), &data); err != nil {
		return
	}
	if expected, err = json.Marshal(data); err != nil {
		return
	}
	actual = bytes.TrimSpace(a.resp.Body.Bytes())
	if len(actual) != len(expected) {
		return fmt.Errorf("expected json length: %d does not match actual: %d", len(expected), len(actual))
	}
	for i, b := range actual {
		if b != expected[i] {
			return fmt.Errorf("expected json does not match actual at character: %s^%s", string(actual[:i]), string(actual[i:i+1]))
		}
	}
	return
}

Hi, I rarely visit any chats, so guess if you wish to have a channel, where people using godog could connect and chat or have discussions. feel free to create such and add a reference in README, I could also place it in the description of repository if there will be people using it. cheers.

I think it's better that you do it as I'm not a core member of godog and DATA-DOG.

does anyone else need a community chat?

Hello, I am stuck with a problem with my REST API test. Below is the scenario:

I have a struct like:

type Status struct {
	ErrorCode 	string	`json:"ERROR_CODE"`
	ErrorText  	string	`json:"ERROR_TEXT"`

}

type OutputResponse1 struct {
	Status Status `json:"STATUS"`
}

type OutputResponse2 struct {
	Status Status `json:"STATUS"`
	Config json.RawMessage `json:"CONFIG"`
}

A byte type variable:

var responseByte []byte

And two different kind of output response:
//--------------1

	responseByte, _ = json.Marshal(OutputResponse1{
		Status: Status{
			ErrorCode: "-2",
			ErrorText:  "Config was not found",
		},
	})

	//------------2
	responseByte, _ = json.Marshal(&OutputResponseSuccess{
			Status: Status{
				ErrorCode: "0",
				ErrorText:  " ",},
			Config: json.RawMessage(body),
	})

The json.Rawmessage is something coming from another source which looks like:
{
"binaryVersion":"1.0.0",
"configVersion":"1.1.1"
}

Now in feature file I have tested out something like this:

//--------------1

And the response should match json:
"""
{
"STATUS": {
"ERROR_CODE": "-2",
"ERROR_TEXT": "Config was not found"
}
}
"""

THIS TEST PASS

The other one being one with json.RawMessage

And the response should match json:
"""
{"STATUS":{"ERROR_CODE":"0","ERROR_TEXT":" "},"CONFIG":{"binaryVersion":"1.0.0","configVersion":"1.1.1"}}

  """

NOW THIS ONE FAILS, EVEN THOUGH THE GODG OUTPUT HAS THE ACTUAL AND EXPECTED SAME TO SAME

------------------------Acutal output of godog test---------------------------
And the response should match json:

"""
{"STATUS":{"ERROR_CODE":"0","ERROR_TEXT":" "},"CONFIG":{"binaryVersion":"1.0.0","configVersion":"1.1.1"}}
"""

Expected json does not match actual:
{"STATUS":{"ERROR_CODE":"0","ERROR_TEXT":" "},"CONFIG":{"binaryVersion":"1.0.0","configVersion":"1.1.1"}}

--- Failed scenarios:

Any idea?

@vickeyshrestha most likely there is a new line in the actual response from your REST api action. try trimming the actual value taken from response body. Usually with similar issues you should check the length, because spaces and all that stuff are not visible. I should have trimmed spaces in this example.

@l3pp4rd Hello, thank for your quick answer. I tried trimming down the leading and trailing white space with the mentioned function. Unfortunately, it did not work out for me. Still showing the same problem. I tried with a very basic example that has a struct with "json.RawMessage" type in it. Still it failed in that case as well.

@l3pp4rd Cool, Thank you for your guidance. Sorry about putting this question here, I did not know that (I am new to golang ). I will open this issue in stackoverflow. :)
