1. Black Box Testing Focuses in the functional requirements of the program It is not an alternative to white-box techniques It is a complementary approach It uncovers a different class of errors Behavioral Testing

2. Black Box Testing Attempts to find errors in the following categories: Incorrect or missing functions Interface errors Errors in data structures Errors in external database Behavior or performance errors Initialization and termination errors

3. Control Structures Information domain Performed early in the testing process Applied during later stages of testing

4. Black Box Testing How is functional validity tested ? How is performance tested? What classes of input makes good cases? Is the system sensitive to certain input values? How are the boundaries of data class isolated? What data rates and volumes can the system tolerate? What effect will specific combinations on data have on system operation?

5. Black Box Testing Graph-based testing methods Equivalence partitioning Boundary Value Analysis Comparison testing Orthogonal Array Testing
