Writing tests for utility classes and static methods is made easier with clear patterns. This skill helps you check pure functions, null handling, edge cases, and boundary conditions. You can generate AssertJ assertions and @ParameterizedTest for string utils, math utils, validators, and collection helpers.
You do not need mocking for these tests because utility methods have no state or side effects. The focus is on verifying correct behavior for all kinds of inputs. This is useful for any developer who wants reliable helper code.
The skill provides ready to use examples and step by step instructions. It saves time and ensures your utility tests are thorough and easy to read.
