    • arguments

      static Arguments arguments(Object... arguments)
      Factory method for creating an instance of Arguments based on the supplied arguments.

      This method is an alias for of(Object...) and is intended to be used when statically imported — for example, via: import static org.junit.jupiter.params.provider.Arguments.arguments;

      Parameters:
      arguments - the arguments to be used for an invocation of the test method; must not be null
      Returns:
      an instance of Arguments; never null

    • argumentSet

      @API(status=MAINTAINED, since="5.13.3") static Arguments.ArgumentSet argumentSet(String name, Object... arguments)
      Factory method for creating an Arguments.ArgumentSet based on the supplied name and arguments.

      Favor this method over Arguments.of(...) and arguments(...) when you wish to assign a name to the entire set of arguments.

      This method is well suited to be used as a static import — for example, via: import static org.junit.jupiter.params.provider.Arguments.argumentSet;.

      Parameters:
      name - the name of the argument set; must not be null or blank
      arguments - the arguments to be used for an invocation of the test method; must not be null
      Returns:
      an ArgumentSet; never null
