what is environment variable
Environment Variable , a variable that accessible
only when the environment is active
Usually used for an app with multiple environment ,
we can use env variable to store variable with same name
and different value to store environment specific data
for example :
xxxNamed app has 3 environments with different
URL and Crendentials
But all endpoints are exactly the same no matter what
environment you work on
so we can create 3 environment called
QA1 , QA2 , QA3 and run same set of request
by selecting different environment.
Only one environment can be active at a time.
