Developer testing is a critical component of software development--yet studies show that developer testing is typically inefficient and ineffective. Significant developer effort is spent without finding defects that should have been found. Learn how to be more efficient and effective by achieving higher test coverage and how to make the software itself more testable. See how to plan and carry out an efficient and effective developer testing strategy. Avoid common testing pitfalls, and learn to determine how much developer testing is enough.

"Very good and interesting material on coverage; a lot to think about. Very interested in Binder and material there. Very good in having the quantitative numbers and examples. The references and guidance are invaluable. There have been a number of 'eye openers'. Really has been enjoyable." -- Jim Roberts, ARUP Laboratories

"I've been to a lot of professional/technical training. This was far and away the best. Filled with valuable learnings from start to finish, well paced, and just the right balance of presentation, lab, and discussion. Thank you!" -- Lane Galloway, POP

"Considering the requirements of my group to do unit testing during this release cycle, the course gave me a solid understanding of how to approach unit testing. Glad I took the course." -- Clifton Epps, ViaSat

"Learning the best practices for software testing where everything I've been doing in the past has been largely self-taught. Melvin was very helpful when answering my questions." -- Aaron Deming, Teledyne CETAC Technologies

"Very good and interesting material on coverage; a lot to think about. Very interested in Binder and material there. Very good in having the quantitative numbers and examples. The references and guidance are invaluable. There have been a number of 'eye openers'. Really has been enjoyable." -- Jim Roberts, ARUP Laboratories

"Clear and engaging examples that complemented the course material. TDD exercises were really fun to do and learn from!" -- Mikhair Atavine, Demonware

"Most Valuable: Formalizing the testing knowledge that I've acquired by experience. Now I see why I thought those were good tests. I can add more good tests and avoid redundant/useless ones." -- Khouri Giordano, Nikon

"Excellent explanation. You are the best instructor I’ve ever met!" -- Joshua Kim, Senior Software Engineer, LoopNet

"Great course; Melvin was a solid instructor." -- Jeffrey Harker, Microsoft

"I like how the class is organized--it makes the principles presented very convincing. I am going to apply them in my design to have testability in mind." -- Catherine Li, CareFusion

"I really appreciated the review of all techniques, and the importance the trainer gives to applying the knowledge to our company's case... Overall, this is the most useful training I had in years!" -- Guillaume Billet, Tom Tom

"Instructor was very good, thorough, communicated well." -- Robert Hope, Technical Manager, LoopNet

"Hands-on exercises were great--broke up the lecture, helped maintain attention. " -- Allen Snook, Philips

"The class really provided me with information that will allow us to be more systematic in our unit testing. Thanks again." -- Cindy Johnson, Medtronic

"I would recommend for every developer." -- Quan Nguyen, DRS Technologies

"Very well presented, both content and pace. " -- Greg Hightower, Tideworks

"Excellent material, using studies to reinforce importance and value of the discussed ideas." -- Travis Milum, McKesson Medical Imaging


You will be able to develop optimal test cases--both functional (black box) and structural (white box).

Who Should Attend

This seminar is intended primarily for software engineers. Software leads, QA leads, and test professionals who want to learn testing from the developer's perspective are also encouraged to attend.
