Suppose program P has been executed against a test suite T consisting of five tests, t1, t2, t3, t4, t5 and t6. A total of six entities are covered by the tests as shown in the following table: 0 (or 1) in a column indicates that the corresponding entity is not covered (or covered). The entities could be basic blocks in the program, functions, def-uses, or any other testable element of interest. Follow procedure CMIMX to find the minimal cover set for the six entities. ----------------------------- 1 2 3 4 5 6 ----------------------------- t1 0 1 0 1 0 1 t2 1 0 0 0 1 0 t3 1 1 0 1 0 0 t4 1 0 1 0 0 0 t5 0 1 0 1 1 0 t6 1 0 0 0 0 0 -----------------------------
