因此,我要阅读这本名为“#34;服从测试山羊”的书。在学习Python时,我在第六章遇到了一个问题。它说我应该能够运行我们在本章和前一章中设置的functional_tests,没有错误;然而,我不断得到一个我不知道如何解决的追溯。

我真的不知道问题是什么(我不擅长Python全部并尝试运行pdb,但我甚至不知道它的一半是什么意思)并且没有人知道我知道并且我已经问过我可以采取哪些措施来解决问题。
提前致谢!
编辑:这里是test_can_start_a_list_and_retrieve_it_later - 只需要注释即可,但def test_can ...行号是19。
def test_can_start_a_list_and_retrieve_it_later(self):
# Edith has heard about a cool new online to-do app. She goes
# to check out its homepage
self.browser.get(self.live_server_url)

self.assertEqual(
inputbox.get_attribute('placeholder'),

)
# She types "Buy peacock feathers" into a text box (Edith's hobby
# is tying fly-fishing lures)
inputbox.send_keys('Buy peacock feathers')
# When she hits enter, the page updates, and now the page lists

# Satisfied, they both go back to sleep
编辑2:这里是check_for_row_in_list_table。请注意,这从文档的第14行开始。
def check_for_row_in_list_table(self, row_text):
table = self.browser.find_element_by_id('id_list_table')
rows = table.find_elements_by_tag_name('tr')
self.assertIn(row_text, [row.text for row in rows])
答案 0 :(得分:2)
在我的工作中发现错误。我显然错过了list.html中的s
<form method="POST" action="/lists/{{ list.id }}/add_item">
