AttributeError：＆＃39;模块＆＃39;对象没有属性＆＃39; TestSpider＆＃39;

Question

我正在尝试使用python中的unittest，但是我收到以下错误：AttributeError: 'module' object has no attribute 'TestSpider'我的测试代码如下

import unittest

from spiders.eshopsite import EshopsiteSpider

### Unit Test for the EshopsiteSpider class

class TestSpider(unittest.TestCase):

    def testExtractAnchor(self):
        testArray = [u'/test1', u'/test1/test2', u'test2']
        testObj = EshopsiteSpider()
        testOutputArray = testObjextractAnchors(testArray)
        self.assertEqual(len(testArray), len(testOutputArray))
        index = 0
        ### A loop is needed to compare each element in the
        ### arrays. To assert if they are equal
        while index < len(testOutputArray):
            varOne = testOutputArray[index]
            varTwo = testArray[index].encode('utf8')[1:]
            self.assertEqual(varOne, varTwo)
            index = index + 1



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

和我的文件夹结构：

完整的堆栈跟踪：

Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'TestSpider'

为了执行测试，我使用了以下命令：python3 -m unittest tests/TestSpider

根据其他测试，我无法弄清楚出了什么问题。即使我在测试函数中注释掉了所有内容，除了第一个语句之外，我也会得到同样的错误。

我希望有人可以指出我正确的方向或帮助解决方案。
