I am a fresher in IT industry. I have heard few software development words like " development, Integrated System Test environment, System Test environment, User Acceptance environment, Production Environment " Performance Test
I need to understand the correct sequence of above environments. Example, when does the IST environment comes into picture. when does UAT comes into picture.
Typically what I understood is the below sequence. Please correct me if I am wrong
Dev -> Integrated System Test -> System Test (Staging) -> User Acceptance Testing (UAT environment) -> Production
Good luck, jazy. I agree with your order as well. Unfortunately some of the industrial terms you'll come across will have dubious meanings. The best thing you can do is work for a place that clearly defines what all these "industrial terms" mean -- because believe me, they will mean different things to different people. I recently received an email from a customer that had a virtual flurry (no, better categorized as a blizzard) of all the testing buzzwords: unit testing, acceptance testing, system testing, functional testing, and blah blah. The customer wanted to make sure we were doing all these things.
At my place, we have Test Levels to define the scope of the test:
Then, we have Test Types to describe the objective of the test:
So, in a nutshell, we use Test Levels to define "how much" of the system we are going to test; and we use Test Types to define "what" we are going to test for. This might seem complicated, but when you have customers sending emails based on industrial buzzwords, it's important to establish a common vocabulary (all part of managing expectations).
