Unit -V Testing Tools and Measurements
The
V-Model, or Validation and Verification model, is an extension of the Waterfall
Model. It emphasizes the validation and verification of the software at every
stage of development.
In the V-Model, each development
stage corresponds to a testing phase. Development activities form one arm of
the "V", while the testing activities form the other arm. The bottom
of the "V" is where the actual coding happens.
Stages of the V-Model:
- Requirements Analysis: Requirements are
gathered and analyzed.
- Corresponding Testing Phase: Acceptance Testing
- System Design: The system architecture is
designed.
- Corresponding Testing Phase: System Testing
- Architectural Design (or High-Level Design):
The system is broken down into smaller units.
- Corresponding Testing Phase: Integration
Testing
- Module Design (or Low-Level Design):
Detailed design for every module.
- Corresponding Testing Phase: Unit Testing
V-Model Testing Tools and
Management:
1. Requirement Management
Tools:
- Tools: DOORS, ReQtest, JIRA (with requirement
management plugins), Confluence
- Purpose: Capture, trace, analyze, and manage
changes in requirements.
2. Test Design and Modeling
Tools:
- Tools: Rational Rose, StarUML, Microsoft Visio
- Purpose: Design system architecture, modules, and
their interactions.
3. Unit Testing Tools:
- Tools: JUnit (for Java), NUnit (for .NET),
TestNG, xUnit, MSTest
- Purpose: Test individual units or components of a
software.
4. Integration Testing Tools:
- Tools: JIRA, TestRail, Postman (for API
testing), SoapUI
- Purpose: Test the interaction between integrated
components.
5. System Testing Tools:
- Tools: Selenium, QTP/UFT, TestComplete,
LoadRunner (for performance testing)
- Purpose: Test the entire system's functionality and
performance.
6. Acceptance Testing Tools:
- Tools: Cucumber (for Behavior Driven
Development), SpecFlow, FitNesse
- Purpose: Ensure the software meets business
requirements and is ready for release.
7. Test Management Tools:
- Tools: Quality Center (QC) or ALM from Micro
Focus, TestRail, Zephyr, QTest
- Purpose: Organize and manage test cases, plan test
runs, track defects, and report on testing progress and metrics.
8. Defect Management/Tracking
Tools:
- Tools: JIRA, Bugzilla, MantisBT, Redmine
- Purpose: Log, track, and manage defects throughout
their lifecycle.
9. Continuous Integration and
Continuous Deployment (CI/CD) Tools:
- Tools: Jenkins, Bamboo, Travis CI, CircleCI
- Purpose: Automate building, testing, and deployment
processes to ensure continuous feedback and quicker releases.
Conclusion:
The
V-Model emphasizes the parallel relationship between development and testing
stages, ensuring that each phase of development is backed by a corresponding
testing phase. By utilizing appropriate tools at each stage, teams can ensure a
structured, methodical approach to both development and testing, resulting in a
more robust software product.
