Hi, when I run a unittest on a form containing a MultipleChoiceField, and
in the unittest I test setting what I think should be a valid field, it
does not pass. It appears that field in question extracts the data is uses
for the test before the test database is created, and actually uses the
production database for the values.
The result of the test and the (altered snippets) are below, if anyone can
help I'd be grateful.
The below example includes a mock of the data fill function, but there is
no difference in the ultimate response, if the mock setup is not used. If
the production database contains the correct IDs the test passes.
