The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

python unittest module: how to create test fixture for multiple tests of server functions with one setUp call?

Asked by akkl in Python Scripting Language

Tags:

Hello,

I have a newbie question on the Python unittest module:

I have a library with lots of functions that interface to a server. To test these I wrote a unittest TestCase like this inside the python file defining the interface, which I've stripped to pseudocode:

# ....define clientAPI

if __name__ == '__main__':
    import unittest
    import os

    class TestclientAPI(unittest.TestCase):
        servername = 'myserver'

        def setUp(self):

            # ...start up myserver

        def tearDown(self):

            # ....shutdown myserver

        def test_clientfunction1(self):

            #...test clientfunction1 against myserver

        def test_clientfunction2(self):

            #...test clientfunction2 against myserver

        def test_clientfunction3(self):

            #...test clientfunction3 against myserver

    unittest.main()

The problem here is that this starts up and shuts down the server before and after every test. In order to avoid contention over the socket and server startup delays, I have to put long sleeps into the setUp and tearDown methods.

How do I restructure this test case so the server-startup and server-shutdown steps for the test fixture happen only at the beginning and end of the entire cluster of test functions?

Thanks much
