Django与Lettuce和Splinter搭配，打开浏览器但不显示任何内容

Question

我正在尝试用lettuce和splinter进行测试。我有一个配置好的django应用，没什么问题。当我运行lettuce，执行一个“应该”在浏览器中访问某个网址的步骤时，它没有返回任何错误，但页面就是不显示出来。

这是我的.feature文件：

Feature: A test 
Scenario: User enters email, ajax will check if it exists
    When I go to the "/home/login/" URL 
    Then I fill in "#id_email" with "abc@def.gih"

这是我的steps.py：

from lettuce import *
from lettuce.django import django_url
from lxml import html
from django.test.client import Client
from nose.tools import assert_equals
from splinter.browser import Browser
from django.test.utils import setup_test_environment, teardown_test_environment
from django.core.management import call_command
from django.db import connection
from django.conf import settings

@before.all
def set_browser():
    setup_test_environment()
    world.browser = Browser('firefox')

@step(u'I go to the "(.*)" URL')
def i_go_to_the_url(step, url):
    world.response = world.browser.visit(django_url(url))

@step(u'I fill in "(.*)" with "(.*)"')
def i_fill_in(step, field, value):
    world.browser.fill(field, value)

它打开了浏览器，但浏览器什么都不显示，测试却成功了，而第二个测试用例失败了，错误信息如下：

Feature: A test        # candidate/feature/index.feature:1

  Scenario: User enters email, ajax will check if it exists # candidate/feature/index.feature:3
    When I go to the "/home/login/" URL             # home/feature/index-steps.py:29
    Then I fill in "email" with "dsfdf@safsdfsd"       # home/feature/index-steps.py:39
    Traceback (most recent call last):
      File "/usr/local/lib/python2.6/dist-packages/lettuce/core.py", line 117, in __call__
        ret = self.function(self.step, *args, **kw)
      File "********/candidate/feature/index-steps.py", line 40, in i_fill_in
        world.browser.fill(field, value)
      File "/usr/local/lib/python2.6/dist-packages/splinter/driver/webdriver/__init__.py", line 240, in fill
        field.value = value
      File "/usr/local/lib/python2.6/dist-packages/splinter/driver/webdriver/__init__.py", line 306, in _set_value
        self._element.clear()
    AttributeError: 'NoneType' object has no attribute 'clear'

请问有人能帮我解决这个问题吗？

Answer 1

我也遇到过同样的问题。你可以写：

When I go to the "http://0.0.0.0:8000/home/login/" URL

而不是

When I go to the "/home/login/" URL

这样一来，一切就会正常了！

你没有解释很多，但可以试试下面的方法

    world.browser.find_by_id(field).fill(value)
