The second speech is devoted to the automation of testing product metrics in UI tests on iOS. Let's talk about how the metric was tested before, and what they wanted to turn it into. Add to this the challenge factors in the form of platform and business process constraints, and this is a great opportunity to share some good insights with the community.
And finally. Do you happen to encounter the same errors over and over again on Kotlin projects? And the point here may not be at all in the human factor, but, for example, in poorly understood principles of programming. If you answered “yes”, then watch 3 videos in which the speaker will analyze the causes of such errors and how you can avoid them.
