A picture’s worth a 1000 tests.

Unit testing asserts can be difficult to use. Approval tests simplify this by taking a snapshot of the results, and confirming that they have not changed.

In normal unit testing, you say assertEquals(5, person.getAge()). Approvals allow you to do this when the thing that you want to assert is no longer a primitive but a complex object. For example, you can say, Approvals.verify(person).
