Fairies, Fakers and Factories - Boost Your Tests with Better Test Data

Discover how to enhance your testing process with better test data in this 26-minute Devoxx conference talk. Learn techniques to generate representative and randomized test data using tools like Java Faker and jFairy. Explore the benefits of creating test data factories to improve productivity and focus on writing meaningful tests. Gain insights into handling different data formats, preventing collisions, and addressing security and privacy concerns. Follow along as the speaker demonstrates practical examples using EasyRandom, DataFaker, and JayFerry, comparing their features and use cases. Understand how to implement these concepts in real-world scenarios, such as building a webshop for board games. By the end of this talk, you'll be equipped with strategies to overcome "desert blindness" in test data creation and streamline your testing workflow.
