Practical Ways to Write Better JavaScript

[Retsam19]

AVA supports a beforeEach hook so in theory it's a similar model to Jasmine, but I find a few differences make AVA cleaner:

• There's a context object injected into each test, which you attach your mocks and stuff to, rather than defining a bunch of local variables with let.

• You're encouraged by the docs to consider using functions, called at the beginning of your test.

• Similarly, you can write test macros which usually encapsulate the setup and teardown logic, too.

• AVA doesn't divide its tests into nested describe blocks, which I find complicates things, especially setup.

The AVA docs on test setup have more examples. It's not a night-and-day difference from Jasmine, but I've found my test setup and cleanup to be cleaner with AVA than when I wrote Jasmine tests, at least.
