Multiple choice technology testing

We can achieve complete statement coverage but still miss bugs because:

  1. The failure occurs only if you reach a statement taking the TRUE branch of an IF statement, and you got to the statement with a test that passed through the FALSE branch.

  2. The failure depends on the program's inability to handle specific data values, rather than on the program's flow of control.

  3. Both A and B

  4. We are not required to test code that customers are unlikely to execute.
