Programming Logics and Testing Techniques

What is the purpose of conditional statements in programming?

• To make decisions based on specified conditions.

• To confuse the programmer

• To slow down the program execution

• To increase the code complexity

What is unit testing and why is it important in software development?

• Unit testing is important in software development to ensure code quality, identify bugs early, facilitate code refactoring, and provide a safety net for future changes.

• Unit testing slows down the development process

• Unit testing is primarily used for debugging after deployment

• Unit testing is only necessary for small projects

Explain one functional testing technique commonly used in software testing.

• Decision Table Testing

• Boundary Value Analysis

• Pairwise Testing

• Equivalence Partitioning

How is stress testing different from other types of testing?

• Stress testing is conducted by end-users, while other types are done by developers.

• Stress testing is only applicable to hardware, while other types are for software.

• Stress testing evaluates system robustness under extreme conditions, while other types focus on functional or performance aspects.

• Stress testing focuses on user interface design, while other types focus on system architecture.

What are some common back-end techniques used in software development?

• Front-end development, UI/UX design, Mobile app development

• Database management, server-side scripting, API development, authentication, security implementation

How do conditional statements help in controlling the flow of a program?

• Conditional statements help in controlling the flow of a program by always executing all blocks of code.

• Conditional statements help in controlling the flow of a program by executing different blocks of code based on specified conditions.

• Conditional statements help in controlling the flow of a program by randomizing the execution order.

• Conditional statements help in controlling the flow of a program by skipping specified conditions.

What are the benefits of writing unit tests for software components?

• Unit tests make code refactoring harder

• Unit tests help in identifying bugs early in the development process, ensure code quality, facilitate code refactoring, provide documentation for the codebase, and aid in regression testing.

• Unit tests slow down the development process

• Unit tests are not useful for identifying bugs

Describe the process of conducting a functional testing on a software application.

• Functional testing does not require any documentation or test cases.

• Conducting functional testing on a software application involves evaluating the software's functionality by testing each function against the requirements.

• Functional testing is only done after the software is released to users.

• Functional testing involves testing the software's design rather than its functionality.

Why is stress testing important for ensuring the reliability of a software system?

• Stress testing helps identify the system's behavior under extreme conditions and uncover potential weaknesses, bottlenecks, or failure points.

• Stress testing is a waste of time and resources.

• Software systems never encounter extreme conditions, so stress testing is unnecessary.

• Stress testing is only useful for hardware, not software systems.

Give an example of a back-end technique used to optimize database performance.

• Caching

• Data Encryption

• Load Balancing

• Indexing
