How we achieved zero errors based on the results of integration tests

If your solutions consist of many systems connected to each other and developing independently, if you are constantly stumbling on errors caused by incorrect interaction of these systems, you must have thought about organizing integration testing. 

In this talk, I will tell you about my experience in organizing this kind of testing, the problems we faced, and how to solve them. Our team had come a long way from a stage when absolutely nothing was possible to a mature team which produces high-quality software. 

Ideas from the talk can be used to create teams when starting any QA projects.
