为什么我不能在另一个.py文件中使用其中一个.py文件中的方法？

Question

This is my code for form with button:

import sys
from ClickerBot import test_ClikerBot

def func1():
    if sys.version_info < (3, 0):
        # Python 2
        import Tkinter as tk
    else:
        # Python 3
        import tkinter as tk
    root = tk.Tk()
    root.title(“Clicker”)

   def startClick():
        root.destroy()
        clicker = test_ClikerBot()
        clicker.test_clicker_bot()

   button1 = tk.Button(root, text=“CLICK CLICK CLICK”, command=startClick())
    button1.pack()
    tk.mainloop()

if __name__ == ‘__main__‘:
    func1()

When I start this file, I receive next error:

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7    /Users/ltst/Desktop/dev/DribbleBot/venv/Scripts/main.py
Traceback (most recent call last):

    func1()

    button1 = tk.Button(root, text=“CLICK CLICK CLICK”, command=startClick())
  File “/Users/ltst/Desktop/dev/DribbleBot/venv/Scripts/main.py”, line 16, in startClick
    clicker = test_ClikerBot()
  File “/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/case.py”, line 191, in __init__
    (self.__class__, methodName))
ValueError: no such test method in <class ‘ClickerBot.test_ClikerBot’>: runTest

But in my ClickerBot class exist this method:

class test_ClikerBot(unittest.TestCase):    
   def test_clicker_bot(self):

Where is problem? I import this code from catalog studio recorder, and start learn python a week ago, because many things for me like magic and google help not every time (Sorry for bad English)

Answer 1

Your code would be ok if your test_ClikerBot class was an ordinary class. The point is that unittest is a very special framework, and TestCase classes are not meant to be used directly, but thru a TestRunner and a TestLoader that both do quite some magic under the hood. This is partly documented , but you'll probably have to read the source code of the existing runners and loaders to really find out how to make the whole thing work. A good starting point might be the already existing GUI testrunner mentionned in the doc:

The script Tools/unittestgui/unittestgui.py in the Python source distribution is a GUI tool for test discovery and execution
