Question

我无法找到一种方法如何使用来自behave.ini的值ApiClient初始化context.config.userdata['url']

behave.ini

[behave.userdata]
url=http://some.url

steps.py

from behave import *
from client.api_client import ApiClient

# This is where i want to pass the config.userdata['url'] value
api_calls = ApiClient('???') 


@given('I am logged as "{user}" "{password}"')
def login(context, user, password):
    context.auth_header = api_calls.auth(user, password)

api_client.py

class ApiClient(object):

    def __init__(self, url):
        self.url = url

    def auth(self, email, password):
        auth_payload = {'email': email, 'password': password}
        auth_response = requests.post(self.url + '/api/auth/session', auth_payload)

        return auth_response.text

首先，在您的behave.ini，格式重要中。也就是说，记下空格：

[behave.userdata]
url = http://some.url

其次，不是在/features/steps/steps.py中创建ApiClient对象，而是应在/features/environment.py内创建它。这个environment.py是什么？如果您不知道，它基本上是一个文件，用于定义测试运行之前/期间/之后应该发生的事情。有关详细信息，请参阅here。

基本上，你会有类似的东西：

<强> environment.py

from client.api_client import ApiClient

""" 
The code within the following block is checked before all/any of test steps are run.
This would be a great place to instantiate any of your class objects and store them as
attributes in behave's context object for later use.
"""
def before_all(context):         
    # The following creates an api_calls attribute for behave's context object
    context.api_calls = ApiClient(context.config.userdata['url'])

稍后，当您想要使用ApiClient对象时，您可以这样做：

<强> steps.py

from behave import *

@given('I am logged as "{user}" "{password}"')
def login(context, user, password):
    context.api_calls.auth(user, password)

我知道这是一个非常老的问题，但答案不是最新的。在当前文档中似乎不需要空格，OP的问题是标头标记。它必须是[behave]

行为：访问步骤定义之外的context.config变量
