Subject [math] testing issue with Kolmogorov-Smirnov bootstrap methods
Date Tue, 24 Nov 2015 10:40:23 GMT
Hi all,

It seems the new bootstrap method introduced in fbc327e9 in order
to solve MATH-1246 creates some random test failures.

The reason is that an EnumeratedRealDistribution instance is
created without a random generator (there are no way to pass
a random generator in the bootstrap method). This
EnumeratedRealDistribution will therefore create a Well19937c
generator with the default constructor, which uses time to seed
the generator. Depending on the way this generator is seeded,
the testBootstrapSmallSamplesWithTies test fails quite often.

Would it be possible to pass a random generator somewhere and
to configure it with a fixed seed for the Junit tests?

best regards,
Luc
