Not every engineer by heart remember these steps and keywords to setup the Environment Variables. Therefore, this will be a quick-guide for any one from an Intern to Senior Lead.

(JTW format as an example : xxxxxx.yyyyy.zzzzzz)
“typ”: “JWT” }

TestLink, one of the famous open-source web-based test-case management tool in the software quality assurance industry. Couple of year ago, I was granted to work along with the tool to not only to manage test-cases, but also to integrate the test-link with the organizational automation framework.
Integration was not an easy task at all initially as there was no proper step-by-step guide to configure, code and setup the integration. Therefore this post is written with the initiative of guiding and assisting anyone who could face the challenge.
Regardless of the test methodology, as either BDD (Behavior Driven Development) or TDD…
