stanfy / behave-rest Goto Github PK

Здравствуйте Олег!

Я работаю инженером по тестированию backend-а. Как начинающий автоматизатор тестирования, осваиваю Python3. 

Во первых, хочу поблагодарить вас за behave-rest - получился очень полезный инструмент для QA-инженера, постоянно используем в работе для тестировния api. :)

Так как я предпочитаю понимать как работает и что делает инструмент, которым пользуюсь, я начал разбираться в структуре фреймворка и сильно так завис на одном моменте. 

Вопрос такой: что такое context.r ? 

Если предназначение context в behave я понимаю, то происхождение  и назначение r поставило меня в тупик.

В behave_rest/steps/init.py неоднократно встречается context.r

Приведу пример:

@step('I want to reuse "{parameter_name}" parameter')
def store_parameter(context, parameter_name): data = context.r.json()
return setattr(context, parameter_name, data[parameter_name])

context.r.json() подозрительно напоминает то, как мы присваеваем объект Responce (модуль requests) в переменную r:

r=requests.get("какой-нибудь урл"), где результат запроса из r потом распарсили в словарь с помощью json().

В дальнейшем, в файле также можно встретить конструкцию context.r. 

Связана ли она с модулем requests и если связана, то где во фреймворке behave-rest описано, что в r присваивается объект Responce?

Спасибо за внимание, буду очень рад если проясните ситуацию :)

Am i missing anything, Could you please help?

Thanks for building this framework. I need to perform a POST requests with user details that accepts application/json, how do I do that please?

Could you please help to resolve this?

Hi.

Great job, thanks.

Is it possible to connect to an https url without checking the certificate?

Thanks for sharing Python BDD framework and its really helpful to build over this.

Could you please help to perform POST operation using same framework?

When I try run the projects (run command line: behave or behave features/twitter.feature) my promt shows the log above:

Exception ImportError: No module named yaml Traceback (most recent call last): File "/usr/local/bin/behave", line 11, in <module> sys.exit(main()) File "/Library/Python/2.7/site-packages/behave/__main__.py", line 109, in main failed = runner.run() File "/Library/Python/2.7/site-packages/behave/runner.py", line 672, in run return self.run_with_paths() File "/Library/Python/2.7/site-packages/behave/runner.py", line 677, in run_with_paths self.load_hooks() File "/Library/Python/2.7/site-packages/behave/runner.py", line 631, in load_hooks exec_file(hooks_path, self.hooks) File "/Library/Python/2.7/site-packages/behave/runner.py", line 304, in exec_file exec(code, globals, locals) File "features/environment.py", line 1, in <module> from yaml import load ImportError: No module named yaml

Any idea?
