​​Code Testing

Software quality is tightly controlled using issue tracking, automatic testing of merge requests, and collaborative code review.

Bison is supported by more than 2000 regression tests.  All new code must be supported by testing.


Bison includes verification tests for linear elasticity, large strain behavior, heat transfer, contact, and many other capabilities.  Details can be found in "Verification of the BISON fuel performance code".


Bison capabilities have been most thoroughly validated for light water reactor fuel performance modeling.  Details can be found in "Validating the BISON fuel performance code to integral LWR experiments" and "Assessment of BISON: A Nuclear Fuel Performance Code".  See also Assessment Cases​ on the main Bison documentation site.
