Easy Random is a Java library that generates random instances of arbitrary Java beans and records via an EasyRandom API extending java.util.Random. It is configurable through EasyRandomParameters controlling seeds, ranges, collection sizes, and randomization depth.

Use cases

• generate random test fixtures for java classes
• create random instances of domain objects for unit tests
• populate java beans with random data
• generate random java records for property-based testing
• seed deterministic random object generation in tests
• replace manual object mother/test data builder boilerplate

When to choose

• you need quick random instances of Java POJOs or records for testing
• you want configurable, deterministic random data generation with seeds
• you want a lightweight, dependency-free ObjectMother alternative on the JVM

When to avoid

• the project is in maintenance mode with only bug fixes, so prefer actively developed alternatives for new projects
• you need realistic, semantically valid data (names, emails) rather than arbitrary random values
• you are not on the JVM or need Java 17+ features on older runtimes
