Agree on and enforce a style guide for tests

What is the need / problem

To agree an enforce a code style guide also for our tests, which are still using the very old RSpec should syntax. Chances are that this syntax won’t work in upcoming versions of RSpec.

Who does it impact

All devs

What is the current impact of this problem

We waste time and energy review the syntax used in a PR when this better done by machines. We would be better off focusing on architecture and implementation.

Using this old syntax may stop us from upgrading RSpec in the future.

What is the benefit in focusing on this

All new tests will be written in the RSpec expect syntax without any devs having to review it and without having to worry about it for future upgrades.

Potential solutions that will solve this problem

Tech debt. Closing this as out of scope of the icebox process.

@sigmundpetersen @sauloperez @maikel @luisramos0 feel free to do with the idea what you will.

Some work got done in but it is now blocked.
