> HaltonSequenceGenerator.skipTo(int index) does not throw a NotPositiveException when the parameter is negative.In the documentation it is stated that an NotPositiveException will be thrown if the parameter value is less than zero.
> However, in this test case:
> {code:java}
> public class HaltonSequenceGenerator_Test{
> public void test() throws Throwable{
> HaltonSequenceGenerator haltonSequenceGenerator = new
> HaltonSequenceGenerator(1);
> try {
> double[] doubleArray =
> haltonSequenceGenerator.skipTo((-4584));
> org.junit.Assert.fail();
> } catch
> (org.apache.commons.math3.exception.NotPositiveException e){
> //NotPositiveException caught and test successful
> }
> }
> } {code}
> The int parameter is negative and a NotPositiveException should be thrown, however the method executes normally, and test case fails.
