How to properly build backend testing on node.js?

Question

Software testing

Hey!
I am writing a rest api on a node. The backend accesses several databases, everything works in docker-compose. I want to cover api with tests, which, preferably, would access the server from a separate container. Among the tests will be testing authorization that works through cookies.
What is the best way to organize testing? What libraries to use?
Thanks in advance.

Answer 1

npm i superagent

Try Gulp, grunt
Throw the tester on the deploy, it will be even better)
You can also add a timeout so that the test does not survive
the server This is how it was on an old project.
