What Is Testing
“Good testing involves balancing the need to mitigate risk against the risk of trying to gather too much information”
Gerald Weinberg
Testing is a search for information
Value: identify risks
Cost: execution time

Risk Management Theatre
“Risk management theatre is the outcome of optimising processes for the case that somebody will do something stupid or bad”
Jez Humble
Release Testing is high cost, low value theatre
Build Quality In
“Cease dependence on mass inspection to improve quality. Improve the process and build quality into the product in the first place”
Dr. W. Edwards Deming, 1900-1993
Testing is an activity, not a phase
Everybody is responsible for quality
Build Quality In
More Releases = Lower Risk
Risk = probability * cost
Smaller, more frequent releases reduce risk
“Decomposing a large batch into several smaller batches reduces the risk of failure”
Don Reinertsen
