Before you start About this series Writing code for an application is just the first phase of a lengthy process required to deliver a robust product quality program. The code must be tested to verify its operation and accuracy. It is also often necessary to analyze the code to eliminate performance bottlenecks and resource waste (especially memory). Code must also be monitored to locate faults, identify usage patterns, look for opportunities for further enhancements and optimizations, and dete
