  8. Anyone Recognize This Phrase? Program Overview The computer science curriculum is designed to prepare students to enter the rapidly expanding computer field. It is based upon the Institute of Electrical and Electronic Engineer Computer Society and the Association for Computing Machinery recommendations for curricula and courses. The four-year undergraduate curriculum in computer science includes a sound preparation in science, mathematics, English, statistics and computing. Students majoring in computer science at Texas A&M will take a 12-hour area of concentration in another department. Electives are available in the areas of: algorithms, languages and computability, software systems, networking, computer systems and architecture, artificial intelligence and cognitive modeling, vision, graphics and robotics and computational science and engineering. Advanced undergraduates may take graduate courses in these areas. …a sound preparation in science, mathematics, English, statistics and computing.

  9. Why is English in the List? • Nearly all jobs require “Excellent communications skills” • Employers will probably see your writing before your programming—laziness or ineptitude in one will be applied to the other • Not just for technical writers • Not just for a job interview • Clear writing will distinguish you from people with equal technical skills

  10. Agenda • Introduction • Overview of Schlumberger • A footnote about your degree program • What is automated testing, and why do it? • Challenges in test automation

  11. What is Testing? • “Testing is an infinite process of comparing the invisible to the ambiguous in order to avoid the unthinkable happening to the anonymous.” - James Bach

  12. Problem Number 1 Development Effort Incremental • Which Leads To: • Risks for customers • Risks for product team • Increased support cost • Debate the finish criteria: • Remove features • Extend deadlines • Add resources Testing Effort Cumulative • Take short cuts: • Don’t test features • Don’t test configurations • Don’t do non-functional tests

  13. Solution: Add Test Automation Development Effort Manual Test Effort Test Automation Effort We can refocus manual test efforts on important, new testing. What if we eliminate repetitive tests?

  14. What Must Automated Tests Do? • Mimic behavior of a user or application in an environment • Validate the results ofthis behavior • Maintain or improve upon standards of otherforms of testing.

  15. What is Test Automation Not? • Not record and playback • Not a cheap alternativeto other methods of testing

  16. Example • The TestComplete version of “Hello World.”

  17. Impact? • Application exists (is installed?) • Application starts without error • Application accepts input without error • Application saves file without error • Application exits without error

  18. Basic Metrics

  19. Problem Number 2 • Question: “Should add feature X?” • Answer: “Hmmm.” • Question: “Should we support configuration X?” • Answer: “Yes.”

  20. Testing Effort Grows on Multiple Dimensions Features Configurations Data Sets

  21. Two Part Solution • All Pairs Testing http://en.wikipedia.org/wiki/All-pairs_testing • Run automated tests in parallel

  22. WebCam of HTC Automation

  23. Impact

  24. Problem Number 3

  25. Agenda • Introduction • Overview of Schlumberger • A footnote about your degree program • What is automated testing, and why do it? • Challenges in test automation

  26. John Wanke • Started at Schlumberger in 2010 • Tested economics, asset management, and enterprise planning applications • Currently I lead the test automation effort for the Production Solutions group (services-based products)

  27. John Wanke • Studied at Wichita State University • Electrical Engineering, Mathematics • Held the following positions before Schlumberger • Lead Systems Analyst / Software Engineer • Lab Systems Administrator • Web master/application developer • I/T Manager • Software Quality Assurance Engineer/Developer for message queueing administration and monitoring • http://www.linkedin.com/in/johnwanke

  28. Management, Marketing, and Machiavelli • Well-known • Established • Easily understood • Simple operation • Alien and foreign • Newcomer • Complex • Requires skill to use

  29. Challenges of Test Automation:Manage Expectations

  30. Merak Enterprise Planning (MEP) Solution Overview

  31. MEP Product Architecture

  32. The Technical Challenge • “The challenge you face is gaining automated / deterministic control of your test environment.” -- Jonathan Lee

  33. The Technical Challenge, Part 1:Known Test Platforms

  34. Merak Enterprise Planning Test Environment

  35. The Technical Challenge, Part 2:Known Testware Development Effort • Software written to test software • Subject to same controls as any other software asset • Versioned to be in sync with app Manual Test Effort Test Automation Effort

  36. The Technical Challenge, Part 3:Find a Tester or Make One

  37. Q & A
