test.SimpleTestCase.assertFieldOutput()

SimpleTestCase.assertFieldOutput(fieldclass, valid, invalid, field_args=None, field_kwargs=None, empty_value='') [source]

Asserts that a form field behaves correctly with various inputs.

Parameters:

Parameters:	fieldclass – the class of the field to be tested. valid – a dictionary mapping valid inputs to their expected cleaned values. invalid – a dictionary mapping invalid inputs to one or more raised error messages. field_args – the args passed to instantiate the field. field_kwargs – the kwargs passed to instantiate the field. empty_value – the expected clean output for inputs in `empty_values`.

fieldclass – the class of the field to be tested.
valid – a dictionary mapping valid inputs to their expected cleaned values.
invalid – a dictionary mapping invalid inputs to one or more raised error messages.
field_args – the args passed to instantiate the field.
field_kwargs – the kwargs passed to instantiate the field.
empty_value – the expected clean output for inputs in empty_values.

For example, the following code tests that an EmailField accepts a@a.com as a valid email address, but rejects aaa with a reasonable error message:

self.assertFieldOutput(EmailField, {'a@a.com': 'a@a.com'}, {'aaa': ['Enter a valid email address.']})
