如何使用 unitest class 测试我的 scrapy 方法

How to test my scrapy method with unitest class

我想在我的蜘蛛中尝试一些方法。 例如在我的项目中,我有这个模式:

 toto/
├── __init__.py
├── items.py
├── pipelines.py
├── settings.py
├── spiders
│   ├── __init__.py
│   └── mySpider.py
└── Unitest
    └── unitest.py

我的 unitest.py 看起来像这样:

# -*- coding: utf-8 -*-                                                           
import re
import weakref
import six
import unittest
from scrapy.selector import Selector
from scrapy.crawler import Crawler
from scrapy.utils.project import get_project_settings
from unittest.case import TestCase
from toto.spiders import runSpider

class SelectorTestCase(unittest.TestCase):

    sscls = Selector

    def test_demo(self):
    print "test"

if __name__ == '__main__':
    unittest.main()

和我的 mySpider.py,看起来像这样:

import scrapy

class runSpider(scrapy.Spider):
    name = 'blogspider'
    start_urls = ['http://blog.scrapinghub.com']

    def parse(self, response):
        for url in response.css('ul li a::attr("href")').re(r'.*/\d\d\d\d/\d\d/$'):
            yield scrapy.Request(response.urljoin(url), self.parse_titles)

    def parse_titles(self, response):
        for post_title in response.css('div.entries > ul > li a::text').extract():
            yield {'title': post_title}

在我的 unitest.py 文件中,如何调用我的蜘蛛? 我试图在我的 unitest.py 文件中添加 from toto.spiders import runSpider,但它没有... 我遇到了这个错误:

Traceback (most recent call last): File "unitest.py", line 10, in from toto.spiders import runSpider ImportError: No module named toto.spiders

我该如何解决?

尝试:

import sys
import os
sys.path.insert(0, os.path.join(os.path.dirname(os.path.realpath(__file__)), '../..')) #2 folder back from current file

from spiders.mySpider import runSpider
