Hello, friends! Could you please give me approaches or software you are using while testing your products? Are you doing it manually or are you writing automated tests?
I write unit, integration, and end-to-end tests. For the Node.JS ecosystem, check out Mocha (https://mochajs.org/) and Chai (https://www.chaijs.com/). Ideally you should automate test execution on git push, or as a part of your deployment process.
