overview
Overview
  • Aim
    • Generating regression test cases
  • Written in C
    • Platform independent
  • Non-deterministic
terminology
Terminology
  • Dimension
    • The type of a variable
    • The type of comparison (>, <, ==)
  • Feature
    • Possible values in a dimension

For instance:

    • typedef enum {FALSE, TRUE} BOOL;
reason behind
Reason behind
  • Exhaustive testing is overkill
    • 12 dimensions of 2 features each: 2^12 = 4096
  • Three-feature combination is enough
usage
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
data structure
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
