variable scope in api

By Obedient Ocelot on Dec 06, 2020

1-GLOBAL variables allow you to access data
between collections, requests, test scripts,
and environments. Global variables are
available throughout a workspace. I use global variables
when I need to quickly test something.

2-COLLECTION variables are available throughout 
the requests in a collection and are independent
of environments, so do not change based on the selected environment.
I use collection variables when
I use single environment like url details.
We can refer to the variable by using {{}}(double curly brace)
and  it can be used anywhere

3-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.

4-LOCAL variables are temporary, and only
accessible in your request scripts. 
Local variable values are scoped to a 
single request or collection run, and are no longer
available when the run is complete.


5-DATA variables come from external CSV and JSON files
to define data sets you can use when running collections
via the Collection Runner.

Only accessible within the same collection and
can not be accessed anywhere else
