What is Factory Boy and how does it improve performance?

Factory Boy is a Python library that helps create test data for your applications. It improves performance by automating the generation of complex data structures, making tests faster and more reliable.

Can you give me an example of how to use Factory Boy?

Sure! You can define a factory for your model, like this:

import factory

class UserFactory(factory.Factory):
    class Meta:
        model = User

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

Then, you can create a user instance with UserFactory(), which will generate a user with random data.

What are the benefits of using Factory Boy over manual data creation?

Using Factory Boy reduces boilerplate code, ensures consistency in your test data, and allows for easy modifications. It also helps in creating complex relationships between models effortlessly.

Are there any limitations to using Factory Boy?

Yes, while Factory Boy is powerful, it may require some initial setup and understanding of your data models. Additionally, it might not cover every edge case, so manual data creation might still be necessary in some scenarios.
