The Secret to Successful Test Automation


5

Let’s start by defining “agile”

Agile teams:

Deliver business value frequently

at a sustainable pace while adapting to the changing

needs of the business Source: Elisabeth Hendrickson


6

The key is “sustainable pace”

Technical debt slows us down

The Death Spiral

High technical debt + insufficient automation = even less time


9

Automated tests are code

public class CalculatorFixture extends

ColumnFixture { public String startDate; public String endDate; public double startBalance; public double endBalance; public String irrTarget; private Calculator calculator = new

Calculator(); private Double irr;

Test code deserves the same respect as production code!
