Overview

In this lesson, we'll discover how multiple assertions can be linked together, and nested together, using the assertAll() API. It provides a useful grouping of dependent information under a common label, which we'll utilize to unit test a data class with many properties.

Summary

  • Group together assertions with assertAll()

Comments

I like this one. Even though it's just adding readability and would have failed anyway, it just feels more organised.

I agree! It's certainly a useful approach when you have several assertions with a common, overarching theme. While I don't utilize assertAll() often, it really brings some structure to test classes for model types.
