Test Automation An Approach to Automated Software Regression Testing Presented by Adnet, Inc Feb 2015

Introduction Automates manual repeatable test processes using formal testing procedure Automates manual repeatable test processes using formal testing procedure Controls test execution, comparison of actual outcomes to predicted outcome with test preconditions Controls test execution, comparison of actual outcomes to predicted outcome with test preconditions Saves time and deduces cost by automating repeated manual testing Saves time and deduces cost by automating repeated manual testing Why Test Automation Repeated manual test prone to human errors (overlooking) Repeated manual test prone to human errors (overlooking) Learning cost of new test teams or new members Learning cost of new test teams or new members Regression test cycles are increasing with distributed development Regression test cycles are increasing with distributed development Wider acceptance of Agile model (needs frequent and more tests) Wider acceptance of Agile model (needs frequent and more tests) Manual test data setup with multiple data-sets increases complexity Manual test data setup with multiple data-sets increases complexity 2 Test Automation – Introduction

Scope and Approach (each software, not enterprise) Scope and Approach (each software, not enterprise) What to Automate (often repeatable tests- regression tests) What to Automate (often repeatable tests- regression tests) Smoke Tests (undocumented exploratory tests) Smoke Tests (undocumented exploratory tests) Individual often repeated test cases Individual often repeated test cases More useful for key business function where accuracy required More useful for key business function where accuracy required Easy accommodates variation in test datasets Easy accommodates variation in test datasets What not to automate What not to automate Stress and Load Test Stress and Load Test Need different tools Need different tools Different Strategy Different Strategy 3 Test Automation – Scope and Approach

8 Results Generated After Execution A snapshot of test result file in excel format. For Illustration Only A detailed log file will also be created. Screenshots stored locally as well as in ALM.
