Hi.
While experimenting on
https://issues.apache.org/jira/browse/MATH-1300
I created a new
JDKRandomGeneratorTest
that inherits from
RandomGeneratorAbstractTest
similarly to the classes for testing all the other RNG implemented in
CM.
The following tests (implemented in the base class) failed:
1.
testNextIntNeg(org.apache.commons.math4.random.JDKRandomGeneratorTest)
Time elapsed: 0.001 sec <<< ERROR!
java.lang.Exception: Unexpected exception,
expected<org.apache.commons.math4.exception.MathIllegalArgumentException>
but was<java.lang.IllegalArgumentException>
2.
testNextIntIAE2(org.apache.commons.math4.random.JDKRandomGeneratorTest)
Time elapsed: 0.015 sec <<< ERROR!
java.lang.IllegalArgumentException: bound must be positive
This is caused by try/catch clauses that expect a
"MathIllegalArgumentException"
but "JDKRandomGenerator" extends "java.util.Random" that for those
methods throws
"IllegalArgumentException".
What to do?
Regards,
Gilles
