How do I use Factory Boy for testing in Python?

Factory Boy is a flexible and easy-to-use library for creating test data in Python. You can define factories for your models and use them to generate instances with default values.

Can you show me a simple example of a factory?

Sure! Here's a basic example:

from factory import Factory, Faker

class UserFactory(Factory):
    class Meta:
        model = User  # Assuming you have a User model

    username = Faker('user_name')
    email = Faker('email')

You can then create a user instance with UserFactory(). This will generate a user with random username and email.

What if I want to customize some fields?

You can easily customize fields when creating an instance. For example:

user = UserFactory(username='custom_user')

This will create a user with the username 'custom_user' while other fields will still be generated randomly.

Can I use Factory Boy with Django?

Absolutely! Factory Boy works great with Django. You can create factories for your Django models just like in the example I showed you.
