The Challenges of End-to-End Testing of Microservices
Microservices work well with independent teams who have end-to-end responsibility and use an automated CI/CD pipeline. Ensuring software quality through end-to-end testing can conflict with rapidly integrating and releasing software components. If an end-to-end test fails, the CI/CD pipelines of all involved microservices are blocked until the problem causing the test to fail is solved.

Applying a Zero-Bug Policy at Redgate
A zero-bug policy is a simple yet effective bug management system that can help you avoid being buried deep in months or sometimes even years-old bugs. Any bugs you agree are serious enough for you to fix, you fix right away, and any other bug will not be fixed and closed. Tom Walsh spoke about how Redgate Software applied the zero-bug policy at Lean Agile Exchange 2020.

Ensuring Software Quality at eBay Denmark
Quality is not only about not releasing bugs to production, it is much more than that. Quality is a product that is user-friendly, easy to access and use, has high performance/short load time, and is about code that is stable and easy to maintain. Jette Pedersen gave a talk about how to ensure good quality products at Swiss Testing Day 2020.
