Application Lifecycle Management

High quality software should be measured by the value it delivers to customers, and high quality software process should be measured by the continual flow of customer value. Modern processes have taught us that managing flow is all about the constraints restricting that flow. Testing, rather than being thought of as a conduit in that flow, is often perceived as an obstacle. It doesn't help that most testers struggle to answer the questions that their managers ask: What has and hasn't been tested? What do we need to test next? Where do we need to shift resources? If it works in the lab, why isn’t it working on those production machines? Where do we need to fix the performance or security? The ability-or inability- to answer these questions can determine the success and budget of a test team as well as how it is valued by its organization.

The system of apprenticeship was first developed in the late Middle Ages. The uneducated and inexperienced were employed by a master craftsman in exchange for formal training in a particular craft. So why does apprenticeship seldom happen within software testing? Do we subconsciously believe that just about anyone can test software? Join Lloyd Roden and discover what apprenticeship training is and-even more importantly-what it is not. Learn how this practice can be easily adapted to suit software testing. Find out about the advantages and disadvantages of several apprenticeship models: Chief Tester, Hierarchical, Buddy, and Coterie. With personal experiences to share, Lloyd shows how projects will benefit immediately with the rebirth of the apprenticeship system in your test team.

Warning: Registry keys may be hazardous to your program's health! Registry key entries in Windows applications-visible or hidden-are often neglected by testers. A registry key entry is a program feature just like any other application function and as such needs to be validated. Michael Stahl describes why registry keys should be accorded special attention during testing and proposes a strategy for mitigating risks posed by incorrect registry key entries. He suggests a test strategy, as well as coding standards for input value and type validation, default values, regeneration, and naming rules. Michael demonstrates the use of correct and incorrect registry keys in common commercial applications.

Test-driven development (TDD) is a new approach for software construction in which developers write automated unit tests before writing the code. These automated tests are always rerun after any codes changes. Proponents assert that TDD delivers software that is easier to maintain and of higher quality than using traditional development approaches. Based on experiences gained from real-world projects employing TDD, Peter Zimmerer shares his view of TDD's advantages and disadvantages and how the TDD concept can be extended to all levels of testing. Learn how to use TDD practices that support preventive testing throughout development and result in new levels of cooperation between developers and testers. Take away practical approaches and hints for introducing and practicing test-driven development in your organization.
