/**
* {@code @DoubleRangeSource} is an {@link ArgumentsSource} that provides access to a range of {@code double} values.
*
* The supplied values will be provided as arguments to the annotated {@code @ParameterizedTest} method.
*
* For more details and examples, see
* the documentation on Range Sources
*
*
* This annotation is {@link Repeatable}, to make it usable with {@link org.junitpioneer.jupiter.cartesian.CartesianTest}.
* If used with {@link org.junit.jupiter.params.ParameterizedTest}, it can only be used once (because {@code ParameterizedTest}
* can only take a single {@link ArgumentsSource}). Using it more than once will throw an {@link IllegalArgumentException}.
* If used with {@link org.junitpioneer.jupiter.cartesian.CartesianTest}, it can be repeated to provide arguments to
* more than one parameter.
*
*
This annotation can be used on a method parameter, to make it usable with
* {@link org.junitpioneer.jupiter.cartesian.CartesianTest}. If used with {@link org.junit.jupiter.params.ParameterizedTest},
* the annotation has to be on the method itself as any other {@link ArgumentsSource}.
*
*
*
* For more details and examples, see
* the documentation on Cartesian product tests
