Test Automation Beyond Test Execution
2 likes258 views
This document discusses test automation beyond just test execution. It introduces model-based testing (MBT) as a potential solution to challenges like tight schedules, low resources, and continuous changes. MBT uses visual models of system behavior to understand all possible scenarios and improve test coverage. It can make the test design process smarter, faster and earlier. MBT frameworks allow requirements analysis, test writing and testing, and maintenance across roles like business analysts, developers and testers. Success requires modeling skills, early adoption, peer reviews, management support, and focusing on concepts before tools. The document advocates integrating MBT with automated testing for maximum benefit.

- 10. MBT Framework: Testing And Beyond Requirements Analysis Planning & Inception Implementation & Maintenance Design & Development Test Writing &Testing Business Analysts/ Developers/ Testers visualize system workflows, collaborate, and develop mutual understanding. Business Analysts & Product Owners use model for customer validations All roles collaborate on model/details, remove ambiguities & gaps. Business & UX Analysts use model for usability reviews. Business Analysts use models for user story mapping Testers start generating high level tests (system level). Developers may use model for validation of design against requirements. Business Analysts & Testers continue to refine model and make final adjustments . Testers re-generate updated tests. Automation Engineer & Testers work on automating flows. Technical Writers may use models to start writing user documentations. Testers generate tests for manual and automated test execution. Testers incorporate test execution results back into model for future RBT analysis. Business Analysts/ Developers/ Testers use models for RBT analysis for business impact Business Analysts & Testers incorporate escaped defects into the model & re-generate updated tests. Business Analysts/ Developers/ Testers apply algorithms for test scope selection for release updates. All roles use model for root-cause analysis.
- 11. Visualization, Collaboration & Communication • Encourages collaboration across all roles – Product Owners, Business Analysts, Developers, Test Analysts • All roles reach agreement earlier in the development cycle (e.g., defining user journeys) • Shared understanding – visual is the key • “Talk” to your team. Use model as a tool to facilitate the communication.
- 12. • Peer & team reviews • Part of the standard process Our Experience with Industry MBT Myths • Adds to traditional test design techniques and practices doesn’t replace them • Test design standards • Examples & reference materials • Stay at user level • MBT impacts the whole test process • A MUST: strong support from management to lead the process and tool changes in the organization. • Focus on the concept before focusing on the tool • Modeling skills are very critical • Support from all roles • This is one of the major perception challenges • New way of thinking – do not fit into “existing box” • Good training, examples, reference materials • Drivers and experts from all roles • Apply Test Case generation strategies & algorithms; intelligent filtering • BEST: Integrate MBT framework with automated testing MBT always correct MBT solves all the problems MBT will cause tests explosion MBT is just tooling
