In our time, the amount of data is constantly increasing. Ozon is visited every month by more than 80 million users and more than 40 million orders created in the second quarter of 2021. This talk is about how to prepare data for tests. Dmitry will use the example of Ozon integration testing to show how teams prepare states for different environments. They have created a special service for creating or searching test data. And use different data sources and write tests on Go.
