A thorough guide to parameterized tests in JUnit 5 using @ParameterizedTest. Covers setup with the junit-jupiter-params dependency, all built-in argument sources (@ValueSource, @EnumSource, @MethodSource, @CsvSource, @CsvFileSource, custom sources), argument converters (default converter, object factories, custom converters with @ConvertWith), and argument accessors/aggregators. Includes practical code examples for each feature and explains lifecycle integration, test naming, meta-annotations, and non-parameterized parameters.
