trailing postgres cluster

[Hassene Ben Salem]

Hi, I'm using the following snippet to run my tests.

import unittest
import testing.postgresql


class MyTestCase(unittest.TestCase):

    @classmethod
    def setUpClass(self):
        self.postgresql = testing.postgresql.Postgresql()

    @classmethod
    def tearDownClass(self):
        self.postgresql.stop()

The problem I'm currently having is that the testing postgres cluster doesn't shutdown if my test run into an Error. Is there a way to avoid this?

I tried the your script as a test, then postgresql shutdown safely.
I used unittest.main(), nosetests and py.test as test runners.
I added following testcase. It raises a simple exception.

    def test_failed(self):
        raise

Could you tell me your situation in detail?

After further analysis, I think it's more of a unittest problem. Here's some code that will generate a trailing test cluster:

import unittest
import testing.postgresql


class MyTestCase(unittest.TestCase):

    @classmethod
    def setUpClass(self):
        print 'setUpClass'
        self.postgresql = testing.postgresql.Postgresql()
        import inexistingpackage

    @classmethod
    def tearDownClass(self):
        print 'tearDownClass'
        self.postgresql.stop()

    def test_error(self):
        cur.help()

    def test_working(self):
        'working test'
        assert 1

In this code, an error occurred during the setup phase. This leads to unittest stopping and tearDownClass not being called at all.

[Takeshi KOMIYA]

I understand.
Test runners skips tearDownClass if setUpClass got error. It's rule of unittest.TestCase.

Please rewrite your setUpClass like following:

    @classmethod
    def setUpClass(self):
        print 'setUpClass'
        try:
             self.postgresql = testing.postgresql.Postgresql()
             import inexistingpackage
        except:
             self.postgresql.stop()

I think this is not a bug of testing.postgresql. so I close this.

Thanks,
