💡 Hint

Common Mistakes

Using Client as a base class instead of TestCase

Using SimpleTestCase which does not support database

Using Form which is not a test class

Use TestCase as the base class to write tests that interact with the database and Django components.

💡 Hint

Common Mistakes

Using 'valid' which is not a method

Using 'validate' which is not a form method

Using 'check_valid' which does not exist

The correct method to check if a Django form is valid is is_valid().

4fill in blank

hard

Fill both blanks to create a form instance with POST data and check validity.

Django

form = [1](data=[2])
self.assertTrue(form.is_valid())

Drag options to blanks, or click blank then click option'

AMyForm

B{'username': 'bob'}

CUserForm

D{'email': '[e-mail]'}

💡 Hint

Common Mistakes

Passing data without the 'data=' keyword

Using wrong form class name

Passing data as a list instead of a dictionary

Create the form instance by calling the form class with data= and a dictionary of POST data.

5fill in blank

hard

Fill all three blanks to test form errors when required fields are missing.

Django

form = [1](data=[2])
self.assertFalse(form.is_valid())
self.assertIn('[3]', form.errors)

Drag options to blanks, or click blank then click option'

B{}

Cname

Demail

💡 Hint

Common Mistakes

Using non-empty data which makes form valid

Checking for a field name not required by the form

Forgetting to check form.errors

Testing an empty form data dictionary should make the form invalid and produce errors for required fields like 'name'.
