行为：访问步骤定义之外的 context.config 变量

Question

我无法找到一种方法如何使用beeve.iniApiClient的值来初始化我的context.config.userdata['url']

行为.ini

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

步骤.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，对于你来说behave.ini，格式很重要。也就是说，记下空格：

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

其次，/features/steps/steps.py您应该在/features/environment.py. 这是什么environment.py？如果您不知道，它基本上是一个文件，定义了测试运行之前/期间/之后应该发生的情况。请参阅此处了解更多详细信息。

本质上，你会得到类似的东西：

环境.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，当您想使用 ApiClient 对象时，您可以这样做：

步骤.py

from behave import *

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