问题描述

我一直在尝试使自己熟悉单元测试，但是却遇到了很多麻烦.我有一个尝试使用Unittest的瓶子应用程序，这似乎不合适，所以现在我正在尝试WebTest.

I've been attempting to familiarize myself with unit testing but have been having a lot of trouble with it. I have a bottle app that I tried using Unittest, which didn't seem appropriate, so now I'm trying WebTest.

问题在于，即使遵循该站点上最基本/最肤浅的示例，我也无法远程操作它.

The trouble is that I can't get it to even remotely work, even following along with the most basic/superficial example on the site.

这里是例子:

from webtest import TestApp
import mywebapp

def test_functional_login_logout():
    app = TestApp(mywebapp.app)

    app.post('/login', {'user': 'foo', 'pass': 'bar'}) # log in and get a cookie

    assert app.get('/admin').status == '200 OK'        # fetch a page successfully

    app.get('/logout')                                 # log out
    app.reset()                                        # drop the cookie

    # fetch the same page, unsuccessfully
    assert app.get('/admin').status == '401 Unauthorized'

我的代码:

@get('/')
def page():
    letters = scorer.get_letter_set()
    c = db_connect()
    c.execute('SELECT player_name,score FROM Scores order by score DESC limit 5')
    data = c.fetchall()
    c.close()

    return template('board', letters=letters, scores=data, letterset=json.dumps(letters))

然后，在控制台中(一个问题是，我似乎无法从文件中获取任何测试代码.如果我在项目目录中运行任何文件，则Bottle将改为运行开发服务器.任何尝试运行测试文件会导致导入错误.)

Then, in the console (one problem is that I can't seem to get any testing code to work from a file. If I run any file in my project directory, bottle runs the development server instead. Any attempt to run test files results in import errors.)

>>> from webtest import TestApp
>>> import board
>>> app = TestApp(board.page)
>>> res = app.get('/')

我收到此错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/webtest/app.py", line 322, in get
    expect_errors=expect_errors)
  File "/usr/local/lib/python2.7/dist-packages/webtest/app.py", line 605, in do_request
    res = req.get_response(app, catch_exc_info=True)
  File "/usr/local/lib/python2.7/dist-packages/webob/request.py", line 1313, in send
    application, catch_exc_info=True)
  File "/usr/local/lib/python2.7/dist-packages/webob/request.py", line 1281, in call_application
    app_iter = application(self.environ, start_response)
  File "/usr/local/lib/python2.7/dist-packages/webtest/lint.py", line 198, in lint_app
    iterator = application(environ, start_response_wrapper)
TypeError: page() takes no arguments (2 given)

推荐答案

正如@ ron.rothman所提到的那样，问题在于您试图将方法包装在TestApp中而不是应用程序中.

As @ron.rothman mentions, the problem is that you are trying to wrap a method inside TestApp instead of the application.

根据您的代码-

@get('/')
def page():
    letters = scorer.get_letter_set()
...

很明显，您使用的是默认应用程序，而不是自己创建Bottle的实例.

its evident that you are using the default application instead of creating an instance of the Bottle yourself.

修复-

进行以下更改-

在page()方法之前添加前两行-

Add these first two lines before you page() method-

app = Bottle()
@app.get('/')
def page():
    letters = scorer.get_letter_set()
...

确保将包含上述代码的文件另存为mywebapp.py

Make sure you save the file containing your above code as mywebapp.py

在单元测试代码中，这样编写包装行-

In your unit test code, write the wrapper line like this-

def test_functional_login_logout():
    app = TestApp(mywebapp.app)
...
