Advanced AssertJ | Break your testing habits

📄️ Extracting properties

When testing collections of complex objects, you often need to verify properties of the contained elements.

The recursive comparison feature of AssertJ allows you to compare complex objects by recursively comparing their fields.

By default, assertions fail fast—the first failed assertion stops test execution and reports the failure.

AssertJ allows you to create custom assertion classes for your domain objects, making tests more readable and expressive.

Writing custom assertion classes manually can be time-consuming, especially for large domain models.

Now it's your turn! Apply the advanced AssertJ techniques you've learned to improve the test code in the orders package.
