Agile Testing


What is Agile testing?

“The job of tests, and the people that develop and run tests,

is to prevent defects, not to find them”- Mary Poppendieck


Agile Test approach

An agile test approach…� Adheres to the principles of Agile & Lean

� Embraces changes late in development

� Handles testing and developmentat the same time

� Works towards potential release every N’th week (that is tested and done)

� Incorporates and utilizes a cross-functional team

� Introduces demands on test environmentand support processes

� Works with a test base that evolveswith knowledge

An agile test approach (Example)

For every feature (within every sprint):• Product Owner (and if possible the customer)

involved in design and prototyping

• Developed using TDD and ATDD

• Pair Programming (and/or Code Review)

• Usability Testing

• Integration Testing (Continuous Integrationand Automated integration tests)

For every sprint:• Exploratory Testing

• User Acceptance Testing

• Performance testing

• Complete Regression Testing

• Customer Acceptance Testing

Iterative = Don’t expect to get it right the first time

Incremental = Build in vertical “slides” (features) rather than “horizontal” (layers)

The Team &the Individual


Agile development introduces demands on peoples personality!

Personality and relations

� Requires Pro-active mentality

� Nothing is served on a silver plate

� Requires more collaboration and communication skills

� Hidden conflicts surface, new conflicts arise

� Everyone have to unlearn and relearn

Staff turn-over… “I just work here…”

“I just work here…” “We have always

done it like this”

“We have always done it like this”
