Localflavor Test Case issues

[James Rivett-Carnac]

Hey,

I'm trying to add localflavor for Singapore, and am running into issues getting my test cases to pass.

When manually validate my test cases by running the validators from the django-admin shell, they pass all my test cases.  But when I run my test cases from the test runner, I get:

AssertionError: ValidationError not raised

and the test case test_postcode seems to be adding another invalid test, None:[u'This field is required.'], but I might be confused by this.

Any help in what I'm doing wrong would be appreciated.

My code is at
