Trends show that Internet of Things grows by 30% every year worldwide, rеaching up to 25 billion(!) devices till 2025. This means that many of the current testers will very soon start their adventure with real hardware devices. It also means that more and more complicated integration with modern services and technologies such as Amazon DRS, Alexa, Behavioral Recognition, vision processing, AI, ML and many more is expected. What are the limitations encountered in such conditions? What are the main challenges and what a modern tester should know before they start their testing game? Why we should focus on safety aspects? And finally, how to find yourself in a testing environment when Time to Market statement has paramount importance in terms of building business models? Dawid will focus on the current challenges and risks coming in the near future and how to deal with them to avoid a safety headache. He will also present the way to easier identify and mitigate them.

  Bonus: How King Uses AI to Test Candy Crush Saga   

Candy Crush Saga is one of the biggest mobile games today that has been around for 7 years. It is increasingly a challenge to test a game that has technical debt combined with new features being added for millions of players. Alex will show us how King is training artificial intelligence (AI) programs (bots) to test its games by mimicking human players. Join Alexander as he discusses how King is taking testing to the next level by using machine learning to train bots to test and evaluate game feature in an unsupervised scalable way. He discusses ways to extend and use AI bots to test parts of code that normally is a challenge to tackle as human tester. Alexander explains how this AI approach can be generalized to test other applications.

  Bonus: Performance Assertion during the Functional Testing   

With this talk Petros will give an introduction to the concept of the Timings API that has been developed by GoDaddy. Most testing teams follow a CI/CD process where Selenium is commonly used for test automation. Selenium WebDrivers provide access to the same APIs as real browsers, including the widely supported W3C performance API. Using Timings API, one can insert some JavaScript code into the WebDriver object, performance data can be collected and posted back to the webservice. The response from the webservice includes a boolean field that testers can use for assertion - just like they would with functional checks! The field indicates whether performance was above/below the baseline.
