Error when running Swagger-tester for Heroku-pets example

[ujjwal08]

I was trying to test heroku-pets example file(http://editor.swagger.io/#/) using swagger tester. I am getting an error-

**ERROR:connexion.api:Failed to add operation for PUT /pet/

ResolverError: <ResolverError: Cannot resolve operationId "None"!>
ERROR:connexion.api:Failed to add operation for POST /pet/

ResolverError: <ResolverError: Cannot resolve operationId "None"!>
ERROR:connexion.api:Failed to add operation for GET /pet/

ResolverError: <ResolverError: Cannot resolve operationId "None"!>
ERROR:connexion.api:Failed to add operation for GET /pet/{petId}

ResolverError: <ResolverError: Cannot resolve operationId "None"!>**
Starting testrun against hero.json or None using examples: True

Below is the code for my test.py file to run my configuration file for heroku-pets, which is i have saved locally in json format(config. file name- hero.json)

from swagger_tester import swagger_test

authorize_error = {
'get': {
'/pet/': [200,400, 404],
'/pet/{petId}': [200,400,404],
},
'post': {
'/pet/': [200,400, 404]
},
'put': {
'/pet/': [200,400, 404]
}
}
swagger_test('hero.json', authorize_error=authorize_error)

Below is my console output when i run my test.py file:

I have installed connexion framework also. How to resolve above errors and What is the expected output for testing ? Actually, I am new to swagger and want to learn how testing is done with help of swagger tester so that i can use this in my organisation.

Hi all,
I'm trying the Connexion library with Swagger, too.
I had the same issue at first but I think it's not a bug, it's just a missing property in our swagger.yaml file.
Please take a look at this file, from the Connexion's petstore example:

https://github.com/hjacobs/connexion-example/blob/master/swagger.yaml

first you need to add the 'operationId' property to your swagger.yaml file:

paths:
  /pets:
    get:
      tags: [Pets]
      operationId: app.get_pets
      summary: Get all pets

then you need to implement the proper function (with the same signature as you defined in swagger.yaml) inside your app:

#!/usr/bin/env python3

import connexion

def get_pets():
  return []  # your code here
 
if __name__ == '__main__':
    app = connexion.App(__name__, 8080,
    specification_dir='./swagger/')
    app.add_api('swagger.yaml', arguments={'title': 'your API title'})
    app.run()

I hope it helps.

@Swalloow @ujjwal08 Does @leonardofoderaro's solution help? Could you turn this discussion into a short stackoverflow post?
