Python Nose2 测试在调用 Class 方法时未完成
Python Nose2 Tests Not Finishing When Class Method Called
当我 运行 我的测试包括使用 setuptools 和 nose2 调用 @classmethod 时，测试套件没有完成它只是继续 运行ning。但是我已经检查过测试确实通过并到达函数的末尾，测试套件只是没有完成 运行ning。如果我使用 decode_auth_token 删除测试，它工作正常。我能够将它缩小到 class 方法，因为我也测试了其他 class 方法，它们会导致同样的问题
有人知道为什么会这样吗？下面是相关的代码片段，没有 post 太多我的代码
我的用户模型中的代码
@classmethod
def decode_auth_token(cls, auth_token):
try:
payload = jwt.decode(auth_token, config.SECRET_KEY, algorithms=['HS256'])
# check the hash of what we expect the token to be and token we got to be the same
if bcrypt.check_password_hash(User.by_id(payload['sub']).api_token_hash, auth_token):
return payload['sub']
else:
return 'Token does not match Api Token.'
except jwt.ExpiredSignatureError:
return 'Signature expired. Please log in again.'
except jwt.InvalidTokenError:
return 'Invalid Token. Please log in again.'
调用下面两个函数也会出现问题
@classmethod
def is_username_taken(cls, username):
return db.session.query(db.exists().where(User.username==username)).scalar()
@classmethod
def is_email_taken(cls, email):
return db.session.query(db.exists().where(User.email==email)).scalar()
尽管调用此函数不会导致问题
@classmethod
def by_username(cls, username):
return User.query.filter(User.username == username).first()
这是测试
import unittest
import sys
from . import AppTestCase, API_ROOT
from app.extensions import db, bcrypt
from app.models import User, UserSchema, Location, Company
class TestUserModel(AppTestCase):
def test_encode_auth_token(self):
user = User.by_username('jdoe')
auth_token = user.encode_auth_token(user.id)
self.assertTrue(isinstance(auth_token, bytes))
def test_decode_auth_token(self):
user = User.by_username('jdoe')
auth_token = user.encode_auth_token(user.id)
self.assertTrue(isinstance(auth_token, bytes))
self.assertEqual(User.decode_auth_token(auth_token), user.id)
print('DONE')
第一个测试工作正常，第二个测试打印出 Done 并正确解码 auth_token return 正确的用户 ID，但不会导致测试套件完成。它只是在打印完成后保持 运行ning。
这是设置脚本，我运行使用python setup.py test
进行测试

根据评论中某人的建议，我使用调试器确定它确实完成了测试。它实际卡住的地方是在 tearDown() 期间。我的以下功能是卡住的地方。
def tearDown(self):
"""Clean db session and drop all tables."""
db.drop_all()
随着调试器的进一步深入，我确定它最终卡住了
for table, fkcs in collection:
if table is not None:
self.traverse_single(table, drop_ok=True, _is_metadata_operation=True)
else:
for fkc in fkcs:
...
更具体地介绍此方法 self.traverse_single(table, drop_ok=True, _is_metadata_operation=True)。我假设它在等待生成器 return 时卡住了？不确定，但下面是我在它再次卡住之前得到的最后几行。
