Black Box Testing Quiz

What is Black Box Testing?

• Testing the internal structure of code

• Testing inputs and outputs without knowing internal code

• Debugging code errors

• Writing automated scripts

Answer explanation

Black Box Testing focuses on evaluating the functionality of software by testing inputs and outputs without any knowledge of the internal code structure. This distinguishes it from other testing methods that examine code internals.

What does Black Box Testing focus on?

• Code syntax

• Internal algorithms

• Inputs and expected outputs

• Database performance

Answer explanation

Black Box Testing focuses on evaluating the functionality of an application by examining its inputs and expected outputs, without any knowledge of the internal code or algorithms.

Which of the following is a type of Black Box Test?

• Unit Testing

• Structural Testing

• Functional Testing

• Code Coverage Testing

Answer explanation

Functional Testing is a type of Black Box Test that evaluates the software's functionality against specified requirements, without looking at the internal code structure. The other options are not classified as Black Box Tests.

Who typically performs Black Box Testing?

• Developers

• Database Administrators

• End-users or Testers

• Network Engineers

Answer explanation

Black Box Testing is typically performed by end-users or testers who evaluate the software's functionality without knowledge of the internal code structure, focusing on input and output rather than implementation details.

Which of the following is NOT tested in Black Box Testing?

• User Interface

• Database performance

• Functionality

• Security

Answer explanation

In Black Box Testing, the focus is on testing the software's functionality, user interface, and security without knowing the internal workings. Database performance is typically assessed through other testing methods, making it the correct choice.

Which of the following is not a part of software testing?

• User Interface

• Database Queries

• Functional Requirements

• System Outputs

Answer explanation

Database Queries are not a direct part of software testing; they are related to data management. Testing focuses on User Interface, Functional Requirements, and System Outputs to ensure the software meets its intended purpose.

What is the goal of Black Box Testing?

• A) Test internal logic

• B) Identify syntax errors

• C) Verify system functionality

• D) Optimize performance

Answer explanation

The goal of Black Box Testing is to verify system functionality without knowledge of internal workings. It focuses on input and output, making option C the correct choice, as it assesses whether the system behaves as expected.

Which testing method examines internal code?

• Black Box Testing

• White Box Testing

• Grey Box Testing

• Regression Testing

Answer explanation

White Box Testing examines internal code, allowing testers to understand the logic and structure of the software. In contrast, Black Box Testing focuses on outputs without knowledge of internal workings.

What is a test case?

• A coding function

• A written program

• A scenario to test inputs and outputs

• A user manual

Answer explanation

A test case is defined as a scenario to test inputs and outputs, ensuring that a program behaves as expected under various conditions. This choice accurately describes the purpose of a test case in software testing.

Which of the following is a valid Black Box Test?

• Verifying login with correct and incorrect credentials

• Reviewing code logic

• Debugging a function

• Optimizing SQL queries

Answer explanation

Verifying login with correct and incorrect credentials is a valid Black Box Test as it focuses on input and output without considering internal code structure, unlike reviewing code logic, debugging, or optimizing SQL queries.
