  3. Overview • Aim • Generating regression test cases • Written in C • Platform independent • Non-deterministic

  4. Terminology • Dimension • The type of a variable • The type of comparison (>, <, ==) • Feature • Possible values in a dimension For instance: • typedef enum {FALSE, TRUE} BOOL;

  5. Reason behind • Exhaustive testing is overkill • 12 dimensions of 2 features each: 2^12 = 4096 • Three-feature combination is enough

  6. Usage Command line arguments: 2..52: features in one dimension • n: n-tuple of features • w: without given combination of features • s: seed the random number generator • o: read old test files • h: help

  7. Example

  8. Comparison

  9. Algorithm

  10. Data Structure • struct feature • struct tu_arr, tu_iter /* tuple array & iterator */ • struct test /* test case, a combination of features */ • struct without, wchain /* restrictions */ • struct state

  11. Modules

  12. General Routine

  13. Integration • Adapter

  14. Fin
