QA

As Quality Assurance professionals, many times we used to talk about this term BAU (Business As Usual) Testing. Many of us know exactly what it is, but yet because of the jargon BAU, we may tend to think it is something else. In a typical software life cycle model of Define-Design-Code-Test-Deploy-Maintain-Retire, most of us pre-dominantly get involved in "Test" phase.

Unit testing is often talked about in software development, and is a term that I've been familiar with during my whole time writing programs. Like most software development terminology, however, it's very ill-defined, and I see confusion can often occur when people think that it's more tightly defined than it actually is.
