Introduction
Risk based testing is a concept which define the roadmap for making test strategy and taking decision on release of product. This concept outlines many of the important aspect of testing when time to market and quality has to be met. How many of times you have tested your product in limited time? I hope you have done it many a times? What approach you normally take when your testing schedule has been reduced and you are asked to test the application in limited schedule? Do you follow any defined approach to overcome such a scenario? I hope many of us “not”. We know all these concepts but making use of it is really difficult as we do not know how to approach with this concept.
Purpose
The purpose of this article is to present a practical approach to Risk based testing based on my experience. It may be applicable or may not be applicable for your day to day activity.

Testing schedule and effort has been reduced.
Process
Entry Criteria
Test Cases & Scenarios are ready
Identification of Important Test Scenario or Cases
The first step is to identify the important test scenario or cases based on below mentioned parameters:
• Capability
• Reliability
• Usability
• Performance
• Installability
• Compatibility
• Supportability
• Testability
• Maintainability
• Portability
• Localizability
Mechanics for Identification and Prioritization of Test Scenarios
To identify and prioritize the test scenarios, you need to prepare a Test Factor matrix and assign test scenarios, weightage based on the importance of above parameters. To carry out this you need to do brainstorming session with your team members.
It is not necessary that you are going to provide score for all the test cases for all the factors. Some of your test cases do not suffice the above factors. In that case you need not to give scoring. This help in focusing only on important cases.
The Test Factor matrix gives you an analysis based on important quality factors that are required to be fulfilled in the product. It helps in identifying your test scenarios which must be executed before the delivery of the product.
The customer input may be required for prioritizing the test scenario based on your analysis.
From Test Factor matrix , you can analyze that “Performance is not a major concern area”, the major concern area are “Usability”, “Reliability”, “Capability”.
Now start with Usability Test Scenarios – execute the cases based on maximum weightage to minimum weightage. Follow the same rule for other factors.
Output
• Test Factor matrix
• Test Priority List
