void RandomVariableStreamLogNormalTestCase::DoRun ( void  )

Implementation to actually run this TestCase.

Subclasses should override this method to conduct their tests.

This test fails sometimes if the required tolerance is less than 3%, which may be because there is a bug in the implementation or that the mean of this distribution is more senstive to its parameters than the others are.

Implements ns3::TestCase.
