我正在尝试生菜和碎片。我有一个配置良好的 django 应用程序，没有问题。当我尝试运行生菜时，使用“应该”访问浏览器中的 url 的步骤，它不会返回任何错误，但不会显示页面。
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"
这是我的步骤.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)
它打开浏览器，浏览器不显示任何内容，但测试成功，第二种情况失败并出现以下错误：
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
