Connect with an expert to learn how to work smarter and learn new ways to uncover more defects. In this issue, Michael Bolton dishes out commentary on why testers who master skills instead of memorizing techniques are relished in the software industry.

The term dependency injection has attained buzzword status within the programming community. Follow Agile developer J.B. Rainsberger as he goes beyond the buzz and breaks down a specific example of how injecting a dependency can improve the testability of your design.

One school of thought says each should do what he's best at and no more. But one company has graduated to a new way of life. Instead of isolating testers and business analysts, the two teams are melded into one—resulting in a more robust product created in less time at a reduced cost. Could this hybrid approach work for you?

Too often testers are thrown into the testing process without direct knowledge of the customers' behaviors and business process. As a tester, you need to think and act like a customer to make sure the software does-in an easy-to-use way-what the customer expects. By defining personas and using them to model the way real customers will use the software, you can have the complete customer view in designing test cases. Get the basics of how to implement customer personas, their limitations, and ways to create tests using them. See examples of good bugs found using personas while learning to write bug reports based on them.
