  • 1. June 27, 2006. Call in at 12:55 pm Eastern Time Carey Schwaber Analyst Forrester Research Teleconference Evaluating Functional Testing Solutions: The Forrester Wave ™ Q2 2006
  • 2. Agenda <ul><li>The what and why of functional testing solutions </li></ul><ul><li>How Forrester evaluated functional testing solutions </li></ul><ul><li>The findings of Forrester’s evaluation </li></ul><ul><li>Recommendations and WIM </li></ul>
  • 3. Agenda <ul><li>The what and why of functional testing solutions </li></ul><ul><li>How Forrester evaluated functional testing solutions </li></ul><ul><li>The findings of Forrester’s evaluation </li></ul><ul><li>Recommendations and WIM </li></ul>
  • 4. Definitions <ul><li>Functional tests: </li></ul><ul><li>Tests to verify that application functionality conforms to predefined specifications </li></ul>
  • 5. What are the key ingredients of a functional testing solution? <ul><li>In scope: </li></ul><ul><ul><li>Manual testing </li></ul></ul><ul><ul><li>Functional test automation </li></ul></ul><ul><ul><li>Test management </li></ul></ul><ul><li>Out of scope: </li></ul><ul><ul><li>Unit testing </li></ul></ul><ul><ul><li>Static analysis </li></ul></ul><ul><ul><li>Performance testing </li></ul></ul><ul><ul><li>Application monitoring </li></ul></ul>
  • 6. “Does your shop conduct any automation of functional test scripts?” Base: 74 IT decision-makers at North American and European companies
  • 7. Pros and cons of manual testing <ul><li>Pros </li></ul><ul><li>Cost of test case design is minimal </li></ul><ul><ul><li>No required tools or tool expertise </li></ul></ul><ul><ul><li>No automation necessary </li></ul></ul><ul><ul><li>No need for lead time prior to test execution </li></ul></ul><ul><li>Can be scripted, exploratory, or both </li></ul><ul><ul><li>Simultaneous learning, test design, and test execution (Bach) </li></ul></ul><ul><ul><li>Useful before, during, and after design and execution of standard manual test scripts </li></ul></ul><ul><li>Cons </li></ul><ul><li>Cost of test execution is high </li></ul><ul><ul><li>Cost = execution time X labor rate </li></ul></ul><ul><ul><li>Execution time is high </li></ul></ul><ul><ul><li>No efficiencies when execution is repeated </li></ul></ul><ul><li>Scripted test execution is tedious </li></ul><ul><ul><li>No creativity required </li></ul></ul><ul><li>All forms are highly error-prone </li></ul><ul><ul><li>Quality depends on tester’s attention to detail over time </li></ul></ul><ul><ul><li>Documentation of test results is another potential source of errors </li></ul></ul>
  • 8. Specialized tool support can improve efficiency of scripted manual testing <ul><li>Tool support helps manual testers: </li></ul><ul><ul><li>Store test plans, test scripts, and test results in a single, secure location </li></ul></ul><ul><ul><li>Share test components (e.g., “login”) across test cases </li></ul></ul><ul><ul><li>Automate data entry and data verification </li></ul></ul>
  • 9. Pros and cons of test automation <ul><li>Pros </li></ul><ul><li>Frees testers for more intelligent types of testing (e.g., exploratory testing) </li></ul><ul><li>Drives down time, cost of test execution </li></ul><ul><li>Permits shops to expand scope of testing efforts </li></ul><ul><li>Cons </li></ul><ul><li>Increases up-front investment in test design </li></ul><ul><li>Easy to waste time automating the “wrong” tests — or the right tests in the wrong way </li></ul><ul><li>Requires more technical expertise, specialized tools support than manual testing </li></ul>
  • 10. A simplified view of the economics of test automation If a test script will be run every week for the next two years, automate the test if the cost of automation is less than the cost of manually executing the test 104 times. Choose to automate when: To calculate the cost of automating a test script: Cost of automation Cost of manually executing the test as many times as the automated test will be executed Cost of test automation Cost of tool(s) Labor costs of script creation Labor costs of script maintenance
  • 11. “Why does your company not perform any test automation?” Base: 38 North American and European IT decision-makers at companies that don’t perform any test automation
  • 12. The right balance varies by test effort <ul><li>Testing team composition </li></ul><ul><ul><li>Programming skills vs. subject matter expertise </li></ul></ul><ul><ul><li>Division of labor that leverages each team members’ strengths </li></ul></ul><ul><ul><li>Assessment of development team’s own testing efforts </li></ul></ul><ul><li>Nature of the application under test </li></ul><ul><ul><li>Application technology </li></ul></ul><ul><ul><li>Application stability </li></ul></ul><ul><li>Timeline </li></ul><ul><ul><li>Time available for creation of automated test scripts </li></ul></ul><ul><ul><li>Expected lifetime of the application </li></ul></ul>
  • 13. The benefits of an integrated test management solution for manual and automated testing <ul><li>Common interface for planning and monitoring all test activities </li></ul><ul><li>Change management for manual and automated test assets </li></ul><ul><li>Submission of defects from manual testing and test automation tool directly to test management tool </li></ul><ul><li>Incremental automation of portions of the test suite </li></ul>
