Risk Based Testing - Revisited

Sreeram Kishore Chavali

9 July 2002


Agenda

  • Examples of Risks

  • Customizing test plan template

  • Discussion and Q&A


Business Risks

  • System forces user to spend more time than he feels appropriate

  • System Crashes resulting in loss of business

  • Corrupts data

  • Delivers slow performance

  • Incorrect Documentation


Software Bugs – Risks Examples

  • Risk Level 5:

    • System crashes

    • Cannot Enter Data

    • Loss of Data

    • Inconsistent Data accepted

    • Invalid data accepted

    • System becomes unusable

    • Mostly Positive Test Cases fall under this Risk Level. 100% chances of user facing this scenario


Software Bugs – Risks Examples

  • Risk Level 4

    • Test Scenarios that are not always encountered

    • System does not work properly at boundary conditions

    • Invalid data and invalid states of application

    • System is usable but causes sporadic problem and gives an impression of being unstable and incomplete

    • > 50% chances of user encountering this scenario


Software Bugs – Risks Examples

  • Risk Level 3

    • Mostly negative test cases

    • Cause application to behave incorrectly

    • Chances of user encountering this scenario is less probability

    • < 30% possibility of user encountering this situation

    • Application is usable and working


Software Bugs – Risks Examples

  • Risk Level 2

    • Any test scenario with less than 10% probability of user encountering this scenario

    • Application behavior not consistent but there are workarounds

    • Acceptable discrepancies


Software Bugs – Risks Examples

  • Risk Level 1

    • Remote GUI Defects: Accelerator not working in a not so frequently used dialog

    • Almost 0% probability of user finding the problem

    • Even if user finds the problem, it is something user would not worry about reporting this issue.


Risk Matrix


Test Plan Vs Test Execution

  • Test Plan enables us to explain test scenario, assumptions, scope and other details

    • Needed in a paragraph format

    • Use Word format to specify

    • Will consists of set of cases

    • Cannot be used in metrics

    • Not changed frequently

  • Test Case: A case independent of test scenario with a defined expected outcome

    • Atomic entity

    • Can be used in metrics

    • Can be changed or removed


Customize the Template to suit needs

  • Customize Template to make it usable

  • Still Achieve Basic objectives

    • One Sheet of all test cases

    • Easy to filter, report and monitor

    • Easy to add/modify case details and status


Realizing Benefits with Risk based test cases and Excel Sheet format

  • Test Execution by Risk

  • Quantifying progress

  • Understand Test Progress and dynamics of developments

  • Concurrent update of Status

  • Continuous addition/modification/deletion of cases
