freezegun VS Moto

* in C++.

On Python, just use freezegun to inject controllable timestamps in response to calls to time methods.

I had much fun with https://github.com/spulec/freezegun

If you're ever in Python-land, freezegun is a super neat library that snags all the time/date related functions and lets you control time from code.

For example, freezegun which is a common testing utility.

FreezeGun is a library that helps with mocking out the datetime.datetime.now function. It is a very useful tool for testing code that uses the datetime library.

Another way of doing so would be to inject the value directly to the method. Python has a very good library to sandbox the tests when using the built-in datetime objects: freezegun. Once again, and unfortunately for us, the project was using arrow so this was not a possibility.

If you do time sensitive tests, use freeze gun to make them reproducible https://github.com/spulec/freezegun

> OpenMoto

I dunno if you're trying to play on "hashimoto" but https://github.com/getmoto/moto#readme would be a prime name collision for any such "OpenMoto" name

But yes, please, to adopting Vault. I don't have a horse in the race about Consul but my suspicion is such an effort would only be worthwhile if trying to adopt Nomad, too, which I gravely doubt

Unfortunately I do not believe AWS provides any "test" gateways. I do know there are mock AWS servers you can run on your own. The one I use is called Moto. It does not cover everything (unfortunately it's the most comprehensive out there AFAIK), but it's decent enough to test most standard calls via the sdk. I'm not sure if it covers authorization though...we tend to use security roles on tasks for authorization.

If using Python use Moto to mock AWS Services

You can use a library such as moto https://github.com/getmoto/moto

The Pythonic motto library mocks AWS services, removing the need to deploy your application or pay for API calls against AWS services. Other programming languages have their motto implementation.

Has anyone managed to configure moto (https://docs.getmoto.org/en/latest/) in a docker container in the similar way LocalStack does?

As for mocking, you can take a look at the moto library for mocking the AWS SDK, or for more simple cases even just use a `unittest.Mock/MagicMock` object. If you're having trouble trying to use the mocks in your code, it's a good sign your code is too highly coupled and it'd pay to re-factor, for example using dependency injection, design patterns like adapter/facade etc. (but don't over-do it)

To add on to the integration tests point, for mocking out your AWS resources you should check out moto if you don't want run your test against real AWS resources as they may cost you and is usually slower.
