Abstract

Disclosed is program that facilitates thorough testing of complex software projects. By randomly generating inputs between valid boundary values, more extensive code-path testing can be performed. By providing a history file, any given test can be reproduced.

Random Walk Test Driver with Audit Trail

      Disclosed is program that facilitates thorough testing of
complex software projects.  By randomly generating inputs between
valid boundary values, more extensive code-path testing can be
performed.  By providing a history file, any given test can be
reproduced.

      The test driver will randomly select among a series of tests to
run.  Once a test is selected, any parameters relating to that test
are randomly generated between boundary values.  The selected test is
then executed with the generated parameters.

      During the course of execution, the test driver will produce a
history file.  This file indicates which tests were selected, and
what parameters were used during the test.  This file can be used as
input to the test driver to reconstruct a particular test sequence.
Thus, if a particular random test leads to a failure, that test can
be reproduced via the audit file.  This facilitates the defect
removal process.
