Test Automation - Keytorc Approach
- 2. Definitions for Test Automation In software testing, test automation is the use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes to predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or add additional testing that would be difficult to perform manually. Test automation is; the use of software to perform or support test activities, e.g. Test management, test design, test execution and results checking.

Test Automation in Software Delevopment Lifecycle Performance, simulator Acceptance tools Requirement specification test Architectural design Test design tools: Logical design tools Physical design tools Management tools Test execution & comparison tools Detailed design Static analysis tools: System test Integration test Code Unit test Coverage tools Dynamic analysis tools Debugging tools
- 5. Key to Success The major key to the success of Test Automation: “To reduce manual testing activities and redundant test operations using a systematic solution to achieve a better testing coverage.”
- 6. Test Automation Decision Test Execution Period ? (Frequency) Maturity & Maintenance Effort ? (Cost) Required Technology ? (Cost, Technology) Cross-platform Support and Reusability ? (Cost, Modularity) Mismatch between Automated and Manual Application Behavior ? (User Experience) Are the Scenarios Automatable? Test Execution Period Not Possible Whenever Possible Regularly Once in a While Costs Much Costs Little

- 12. Object-Based Recognition Advantages Very flexible controls Deep-dive automation chance Not sensitive for mature applications Disadvantages Platform dependent Unified control handicap Have maintenance issues for low quality code
- 13. Image-Based Recognition Advantages Automates everything appears on screen Platform independent Valid for web, desktop and mobile Easy-to-use Disadvantages Cannot automate non-GUI software Extremely-sensitive to screen properties Less flexible than object-based recognition
