Scenario Matrix Template

About

A Scenario Matrix Template is a structured table that lists possible test scenarios along with their conditions, inputs, expected behaviour, and outcomes. For Maintainability Testing, this template helps QA teams ensure the system is easy to maintain, update, and troubleshoot over its lifecycle.

The matrix captures both functional and non-functional scenarios related to:

• Ease of code modification

• Impact of changes on existing functionality

• Effort required to diagnose and fix defects

• Documentation and maintainability-related standards

This approach allows for systematic coverage, so testers can plan and execute maintainability-related validations in a clear, traceable manner.

Template

Scenario ID	Scenario Description	Preconditions	Test Data / Inputs	Steps to Execute	Expected Result	Priority	Remarks
MT-01	Verify ease of code modification for a small bug fix	Stable build available	Source code with minor bug identified	Modify relevant code, rebuild, redeploy	Change can be implemented and deployed with minimal effort and no unintended side effects	High	Helps measure code changeability
MT-02	Validate impact analysis accuracy	Change request documented	Change request affecting a specific module	Perform impact analysis using tool or manually	All dependent modules and affected components identified correctly	High	Supports maintainability planning
MT-03	Check regression coverage after modification	Automated regression suite available	Modified build	Run regression suite	All existing features function as expected, no new defects introduced	High	Ensures stability after changes
MT-04	Evaluate documentation accuracy after update	Updated code changes	Code change log	Review updated system documentation	Documentation reflects the latest code changes accurately	Medium	Supports future maintenance work
MT-05	Measure time taken for defect diagnosis	Known defect in system	Logs and monitoring tools	Attempt to identify root cause	Root cause identified within acceptable timeframe	Medium	Measures diagnosability aspect
MT-06	Validate reusability of components	Existing reusable component	Requirement for similar functionality	Implement feature using existing component	Component can be reused with minimal modification	Low	Improves maintainability by reducing effort
MT-07	Verify maintainability under time pressure	Urgent change request	Production environment copy	Apply emergency fix	Fix deployed quickly without causing further issues	Medium	Simulates high-pressure scenarios
