使用 unittest 测试烧瓶应用程序时出错 [英] Error while testing flask application with unittest

问题描述

我有

<块引用>

ModuleNotFoundError: 没有名为project"的模块

尝试运行 test_req.py 时我的项目结构是:

├──实例/│ ├──烧瓶.cfg├──项目/│ ├── __init__.py│ ├── base_processing.py│ ├──模型.py|├── 视图.py│ ├──模板/│ │ ├── base.html│ │ ├── login.html│ │ ├── note.html│ │ ├── notes.html│ └── 静态/│ ││ └── 测试/│ ├── test_req.html├── 运行.py

我的 UnitTest 文件是:

# project/test_req.py导入单元测试导入操作系统从项目导入应用程序from project.models import db, User, Note从 project.views 导入 *TEST_DB = 'test.db'类 RequestTests(unittest.TestCase):@类方法def setUpClass(cls):app.config['TESTING'] = Trueapp.config['WTF_CSRF_ENABLED'] = Falseapp.config['DEBUG'] = Falseapp.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + \os.path.join(app.config['BASEDIR'], TEST_DB)app.secret_key = 'staytrue'cls.app = app.test_client()定义设置(自我):db.create_all()def 拆解(自我):db.drop_all()def test_main_page(self):response = self.app.get('/', follow_redirects=True)self.assertEqual(response.status_code, 200)def test_auth(self):u = 用户(用户名 =测试名1"，密码 =1234567"，电子邮件 =网络@mail.com")db.session.add(u)db.session.commit()response = self.app.post('/login', data=dict(username='testname1', password='1234567'), follow_redirects=True)使用 self.app.session_transaction() 作为 sess:self.assertEqual(sess['username'],'testname1')如果 __name__ == "__main__":单元测试.main()

当我从我的根目录运行它时，我的测试也可以很好地使用nose2.这也是我第一次以这种方式组织我的项目布局.

解决方案

Module 不是文件夹，它应该是一个 .py 文件.由于您没有 project.py 文件，因此您不应指定 from project import app.

指定from project import app意味着有project.py文件，你想从这个文件导入类app.>

如果您的 test_req.py 和 app.py 文件位于同一文件夹中，则只需在您的 import app 中使用:代码>test_req.py

也替换:

from project.models import db, User, Note从 project.views 导入 *

到

from models import db, User, Note从视图导入 *

进一步阅读:

• /folder1/MyPythonFile1.py 文件看起来像这样:

  class Class1:def __init__(self):经过类 Class2:def __init__(self):经过

  和 /folder1/folder11/MyPythonFile2.py 文件看起来像这样:

  类 Class3:def __init__(self):经过

  文件 /folder2/MyApp.py 使用上述文件中的类，如下所示:

  from folder1.MyPythonFile1 import Class1从 folder1.folder11.MyPythonFile2 导入 Class3obj1 = Class1()obj3 = Class3()

  将此示例应用于您的特定案例并相应地更新您的导入.

  I have

  ModuleNotFoundError: No module named 'project'

  while trying to run test_req.py My project structure is:

  ├── instance/
  │   ├── flask.cfg
  ├── project/
  │   ├── __init__.py
  │   ├── base_processing.py
  │   ├── models.py
  |   ├── views.py
  │   ├── templates/
  │   │   ├── base.html

  │   └── static/
  │   │ 
  │   └── tests/
  │       ├── test_req.html
  ├── run.py
  

  My UnitTest file is:

  # project/test_req.py
  
      import unittest
      import os
  
      from project import app
      from project.models import db, User, Note
      from project.views import *
  
      TEST_DB = 'test.db'
  
      class RequestTests(unittest.TestCase):
  
          @classmethod
          def setUpClass(cls):
              app.config['TESTING'] = True
              app.config['WTF_CSRF_ENABLED'] = False
              app.config['DEBUG'] = False
              app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + \
                  os.path.join(app.config['BASEDIR'], TEST_DB)
              app.secret_key = 'staytrue'
              cls.app = app.test_client()
  
          def setUp(self):
              db.create_all()
  
          def tearDown(self):
              db.drop_all()
  
  
          def test_main_page(self):
              response = self.app.get('/', follow_redirects=True)
              self.assertEqual(response.status_code, 200)
  
          def test_auth(self):
              u = User(username='testname1', password='1234567', email='[e-mail]')
              db.session.add(u)
              db.session.commit()
              response = self.app.post('/login', data=dict(username='testname1', password='1234567'), follow_redirects=True)
              with self.app.session_transaction() as sess:
                  self.assertEqual(sess['username'], 'testname1')
  
  
      if __name__ == "__main__":
          unittest.main()
  

  Also my test work just fine with nose2, when I run it from my root directory. Also this is the first time I'm organizing my project layout this way.

  解决方案

  Module is not a folder, it should be a .py file. As you don't have project.py file, you should not specify from project import app.

  Specifying from project import app means that there is project.py file and you want to import class app from this file.

  if your test_req.py and app.py files are located in the same folder, then just use: import app in your test_req.py

  Also replace:

  from project.models import db, User, Note
  from project.views import *
  

  to

  from models import db, User, Note
  from views import *
  

  Further reading:

  • Python modules

  • Importing

  Also, I would recommend to use PyCharm Community Edition, it is free, multilpatform and open source, and will help you to solve such tasks just via two mouse clicks.

  Assume we have the following project structure in the root folder of our project:

  /folder1/MyPythonFile1.py
  /folder1/folder11/MyPythonFile2.py
  /folder2/MyApp.py
  

  /folder1/MyPythonFile1.py file looks like that:

  class Class1:
      def __init__(self):
          pass
  
  
  class Class2:
      def __init__(self):
          pass
  

  And /folder1/folder11/MyPythonFile2.py file looks like that:

  class Class3:
      def __init__(self):
          pass
  

  File /folder2/MyApp.py uses classes from aforecited files and looks like that:

  from folder1.MyPythonFile1 import Class1
  from folder1.folder11.MyPythonFile2 import Class3
  
  obj1 = Class1()
  obj3 = Class3()
  

  Apply this example to your particular case and update your imports accordingly.
