At various conferences, people always talk about how to write more tests, how to make them shorter, longer, and which automation tools to use. Meanwhile, the test environment itself and the state of it can have a strong effect on the behavior of your application and tests. For example, let's see what happens to the application if you turn Wi-fi off or change the theme in the system. It's interesting and will allow you to break out of the routine of endless writing and support of autotests.
Don't think the talk will be interesting only for the tester. Developers will find out where bugs can hide and how to protect themselves from their appearance.
