Testing and Debugging Programs |
Even when your program compiles cleanly, you must also test the program by running it. Running a program helps you detect errors in statements with ampersand substitution, errors in logic, and errors in any nested programs.
To test a program by running it, use a full set of test data that is typical of the data that the program processes. To confirm that you test all the features of the program, including error-handling mechanisms, run the program several times, using different data and responses. Use test data that:
Falls within the expected range
Falls outside the expected range
Causes each section of a program to execute
