Question

使用鼻子测试时，变量是否可以从cmd移动到我的模块？

场景：我正在运行需要针对网站的生产和沙箱版本运行的selenium测试（www.sandbox.myurl.com和www.myurl.com）

我写了一个自定义的鼻子插件，让我可以设置针对

运行的环境

已编辑的代码

env = None

class EnvironmentSelector(Plugin):
"""Selects if test will be run against production or sandbox environments.
"""

def __init__(self):
    Plugin.__init__(self)
    self.environment = "spam"  ## runs against sandbox by default

def options(self, parser, env):
    """Register command line options"""
    parser.add_option("--set-env",
                      action="store",
                      dest="setEnv",
                      metavar="ENVIRON",
                      help="Run tests against production or sandbox"
                      "If no --set-env specified, runs against sandbox by default")

def configure(self, options, config):
    """Configure the system, based on selected options."""

    #set variable to that which was passed in cmd
    self.environment = options.setEnv
    self.enabled = True

    global env
    print "This is env before: " + str(env)
    env = self.passEnv()
    print "This is env after: " str(env)
    return env

def passEnv(self):
    run_production = False

    if self.environment.lower() == "sandbox":
        print ("Environment set to sandbox")
        return run_production

    elif self.environment.lower() == "prod":
        print ("Environmnet set to prod")
        run_production = True
        return run_production

    else:
        print ("NO environment was set, running sandbox by default")
        return run_production

在我的包中，我有一个@setup函数，在运行测试套件之前将相应的URL传递给webdriver。

在我的setup()模块的顶部，我有

from setEnvironment import env

我在设置功能

中包含了值为env的print语句

Whiles env在setEnvironment.py中设置为True，它被导入为None，这是env的原始作业。

如何让变量成功导入@setup？

SETUP.PY

以下是我每次调整setEnvironment脚本时运行的内容。

from setuptools import setup

setup(
    name='Custom nose plugins',
    version='0.6.0',
    description = 'setup Prod v. Sandbox environment',
    py_modules = ['setEnvironment'],
    entry_points = {
        'nose.plugins': [
            'setEnvironment = setEnvironment:EnvironmentSelector'
            ]
        }
    )

看起来你正在这样做，变量的值是在导入时分配的。尝试这样的事情：

#at the top of the setup() module
import setEnvironment
...

#in setup() directly
print "env =", setEnvironment.env

您的代码中也存在一些小错字。以下应该有效（setEnvironment.py）：

from nose.plugins.base import Plugin

env = None

class EnvironmentSelector(Plugin):
    """Selects if test will be run against production or sandbox environments.
    """

    def __init__(self):
        Plugin.__init__(self)
        self.environment = "spam"  ## runs against sandbox by default

    def options(self, parser, env):
        """Register command line options"""
        parser.add_option("--set-env",
                          action="store",
                          dest="setEnv",
                          metavar="ENVIRON",
                          help="Run tests against production or sandbox"
                          "If no --set-env specified, runs against sandbox by default")

    def configure(self, options, config):
        """Configure the system, based on selected options."""

        #set variable to that which was passed in cmd
        self.environment = options.setEnv
        self.enabled = self.environment

        if self.enabled:
            global env
            print "This is env before: " + str(env)
            env = self.passEnv()
            print "This is env after: " + str(env)
            return env

    def passEnv(self):
        run_production = False

        if self.environment.lower() == "sandbox":
            print ("Environment set to sandbox")
            return run_production

        elif self.environment.lower() == "prod":
            print ("Environmnet set to prod")
            run_production = True
            return run_production

        else:
            print ("NO environment was set, running sandbox by default")
            return run_production

这是我的测试代码（pg_test.py），用直接python运行：

import logging
import sys

import nose

from nose.tools import with_setup

import setEnvironment

def custom_setup():
    #in setup() directly
    print "env =", setEnvironment.env


@with_setup(custom_setup)
def test_pg():
    pass

if __name__ == '__main__':   
    module_name = sys.modules[__name__].__file__

    logging.debug("running nose for package: %s", module_name)
    result = nose.run(argv=[sys.argv[0],
                            module_name,
                            '-s',
                            '--nologcapture',
                            '--set-env=prod'
                            ],
                      addplugins=[setEnvironment.EnvironmentSelector()],)
    logging.info("all tests ok: %s", result)

当我跑步时，我得到了：

$ python pg_test.py
This is env before: None
Environmnet set to prod
This is env after: True
env = True
.

Ran 1 test in 0.001s

OK

使用nose插件将布尔值传递给我的包
