Black box testing focuses on the:

• Internal code structure

• External behavior of the system

• Source code logic

• Compiler performance

Which of the following is NOT a black box testing technique?

• Boundary Value Analysis

• Control Flow Testing

• Decision Table Testing

• Equivalence Partitioning

The main purpose of black box testing is to:

• Verify code syntax

• Validate functional requirements

• Check compiler errors

• Test hardware interfaces

In black box testing, test cases are derived from:

• Software specifications

• Source code

• Compiler reports

• Database schema

Equivalence Partitioning divides:

• Source code lines

• Input data into valid and invalid classes

• Loops and branches

• Software modules

In Equivalence Partitioning, one test from each partition:

• Represents all values in that partition

• Tests only boundary values

• Tests the entire code

• Requires exhaustive testing

Boundary Value Analysis focuses on:

• Average values

• The edges of input domains

• Random inputs

• User interface

Which of the following is an example of a boundary value?

• Middle value of range

• Minimum and maximum inputs

• Random test data

• Repeated values

Decision Table Testing is useful for:

• Linear programs

• Simple inputs

• Complex business rules

• Structural coverage

A Decision Table typically includes:

• Loops and variables

• Conditions and actions

• Statements and functions

• Classes and objects
