Question

I have defined a custom error but if I test if custom error gets raised, it fails.

My models.py:

class CustomError(Exception):     '''     This exception is my custom error     '''  class Company(models.Model):     name = models.CharField(max_length=200)      def test_error(self):     raise CustomError('hello') 

and in my tests.py:

import unittest from myapp.models import Company,Customer,Employee,Location,Product,ProductCategory,AllreadyPayedError,CustomError  class CompanyTestCase(unittest.TestCase):     def setUp(self):         self.company = Company.objects.create(name='lizto')      def test2(self):         self.assertRaises(CustomError, self.company.test_error) 

The test fails with this output:

====================================================================== ERROR: test2 (myapp.api.tests.CompanyTestCase) ---------------------------------------------------------------------- Traceback (most recent call last):   File '/Users/......./tests.py', line 27, in test2     self.assertRaises(CustomError, self.company.test_error)   File '/System/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/unittest.py', line 320, in failUnlessRaises     callableObj(*args, **kwargs)   File '    /Users/....../models.py', line 17, in test_error     raise CustomError('hello') CustomError: hello  ---------------------------------------------------------------------- Ran 18 tests in 1.122s 

Anybody an idea what I should do to test if CustomError gets raised

Thanks Andy for your answer the problem was however that I was using the wrong/different kinds of imports: In my settings in my INSTALLED_APPS I had myproj.myapp

After I changed:

from myapp.models import Company,CustomError  

To:

from myproj.myapp.models import Company,CustomError  

It worked as expected
