2. What’s Agile Testing?

3. It’s a mindset
it’s a different way of thinking about testing
it’s about re-thinking software testing

4. The tester in the XP discipline helps the customer to choose and write
acceptance tests, to automate them. He or she serves also as a coach
developer in software testing techniques. He or she is not responsible for finding
trivial bugs, this being responsibility from the developers themselves. He or she
doesn’t work isolated, instead, it’s part of the team. He or she thinks in the
tests that will go to CI, and help developers in pair to solve issues.

36. Testimonials

37. "Before understanding the importance of automated tests it was like more work,
but after using tests to guide me on the development, I could think better in the
software architecture to solve problems and feel safety during the deployments"
~@marioLopez
"Having a coach that helps me to develop software with quality in mind gave me
more confidence than someone just testing and pointing my errors and mistakes”
@edmargomes
"The automated tests made more sense to me in the moment I needed to refactor
an important part in the application, and today I feel good that doing a big refactoring
will not compromise my weekend, because I know things are being constantly tested
=)"
~@troll

40. Conclusion

41. Agile testing is about people working as a team
to develop software with quality, independent of
roles, whether testers or developers.
