In Madrid, Spain, Matthew Heusser, a software delivery consultant and writer, attended the ExpoQA conference where he was surprised by the culture shock of speaking English in a predominantly Spanish-speaking audience. He observed two major categories in testing: day-to-day feature testing and release-testing after code completion, which is often compressed to reduce time. This compression can slow down delivery. He also noted a significant gap between legacy teams that have not modernized and newer teams starting from scratch. The use of techniques like DevOps can help bridge this divide. In his tutorial on lean software testing, he emphasized the importance of reducing batch size and variability in work to improve flow and reduce queues. He also discussed performance testing types, including front-end and back-end testing, synthetic monitoring, and application usage patterns. The panel discussion touched on topics such as whether testers will need to learn coding skills, how to convince management of QA's importance, the future of testing, and the lack of testing education worldwide. Matthew highlighted the limitations of certifications like ISTQB, which he believes can only teach a few technical tools in a short period.
