Software Testing- Black Box

Which of the following is the main focus of boundary value analysis?

• Testing inputs at the system's boundaries

• Testing random input values

• Testing only valid inputs

• Testing system performance

Boundary value analysis is based on which principle?

• Errors are most likely to occur at boundaries

• Errors occur randomly

• Complex conditions lead to errors

• Systematic testing prevents all errors

For input range 5–15, which value would NOT be considered a boundary value?

• 5

• 15

• 10

• 4

Equivalence partitioning is primarily used to:

• Test performance

• Reduce the number of test cases

• Detect boundary defects

• Test non-functional aspects

Which of the following is an equivalence class for 'age must be between 18 and 65'?

• 18, 19, 20

• 17, 66

• 18–65, 65

• Boundary values only

What is a decision table used for in software testing?

• To handle inputs with conditions and their corresponding actions

• To test database queries

• To identify boundary values

• To check performance metrics

How many decision rules are needed for a decision table with 3 conditions and 2 possible values per condition?

• 3

• 5

• 6

• 8

Decision table testing is best suited for:

• Simple systems with few inputs

• Systems with complex combinations of inputs and actions

• Functional testing only

• Load testing

State transition testing is most useful when:

• There are limited input ranges

• The system behaves differently based on its state

• The system is stateless

• The system performs high-volume transactions

In state transition testing, a transition represents:

• An event that changes the system state

• A series of test cases

• A state that does not change

• A condition that does not trigger an action
