Voice User Interface (VUI) is a relatively new and promising direction in development. Although the omnipotent assistant Alice and the processes of developing skills have already buzzed everyone's ears information about testing voice interfaces is still very little. Faced with the challenge of testing a voice app I immersed myself in the research of ways and tools to test this "beast". I was trying to use my experience of testing products at GUI for VUI, but I faced a lot of issues. As a result, I formed an optimal testing process for myself, fixed the features and even created a small cheat sheet that simplifies the work of the voice application tester.
