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,
|Step 1: Create your scenario|
|Step 2: Write that scenario in English|
|Step 3: Translate english to Code|
|Step 4: Create Code so it works|
|Step 5: Run your test for feedback while you code|
|Step 6: Approve result so it continues to work|
|Step 7: Change the requirement|
|Step 8: See the new solution|
|Step 9: Re-approve so it continues to work|
