What is the main purpose of using a testing framework like JUnit or TestNG?
- To automate unit and integration tests
- To create user interfaces
- To manage software development projects
- To write software documentation
JUnit and TestNG are testing frameworks that automate the execution of unit and integration tests, making it easier to validate code and improve software quality.
One of the limitations of traditional SDLC is that testing is often relegated to the _____ phase, which can lead to delays.
- Development
- Planning
- Requirements
- Testing
One of the limitations of traditional SDLC is that testing is often relegated to the Development phase. This means that testing occurs late in the cycle, which can lead to delays and increased costs due to the identification and rectification of defects late in the process. It is more effective to incorporate testing earlier in the process to catch issues sooner.
Which aspect of database design ensures that there is minimal redundancy and dependency by organizing fields and tables of a database?
- Data Serialization
- Data Validation
- Database Fragmentation
- Database Normalization
Database Normalization is the process of organizing data in a database to minimize redundancy and dependency, which leads to a more efficient and reliable database structure.
A team is developing a real-time gaming application. During which type of testing would they assess the application's responsiveness and stability under peak user load?
- Integration Testing
- Performance Testing
- System Testing
- Unit Testing
In this scenario, the team needs to assess the application's responsiveness and stability under peak user load, which is the primary goal of performance testing. Performance testing evaluates system behavior under different conditions and helps identify bottlenecks and issues.
What challenges might a development team face when implementing pair programming as a code review technique?
- Improved code quality and efficiency
- Increased productivity and quality issues
- Reduced collaboration
- Reduced knowledge sharing between team members
Pair programming, as a code review technique, may lead to reduced knowledge sharing between team members. While it can enhance code quality and efficiency, it may challenge knowledge distribution.
Which prototyping model is characterized by building a partial implementation of a system and then progressively expanding and refining it?
- Agile Model
- Incremental Model
- Spiral Model
- Waterfall Model
The Incremental Prototyping Model involves building a partial implementation of the system and then progressively expanding and refining it by adding new features or functionality.
What is a limitation faced by organizations when trying to shift from a traditional SDLC approach to Agile methodologies?
- Difficulty in changing organizational culture and mindset.
- Enhanced process control.
- Improved documentation.
- Increased project predictability.
Shifting from traditional SDLC to Agile often faces the limitation of changing the organizational culture and mindset. Agile requires a more flexible, collaborative, and adaptive approach, which can be challenging for organizations used to a more structured and hierarchical culture.
What does the acronym SDLC stand for in the context of software development?
- Software Deployment Cycle
- Software Development Loop
- System Development Life Cycle
- Systematic Development
SDLC stands for "System Development Life Cycle." It is a structured approach to software development that defines stages and tasks, ensuring the systematic creation of high-quality software.
The _____ model in SDLC is characterized by its focus on risk assessment and iterative development.
- Agile
- Spiral
- V-Model
- Waterfall
The Spiral model in SDLC is characterized by its focus on risk assessment and iterative development, making it suitable for complex projects.
In the context of Configuration Management, what is the significance of maintaining a Configuration Item (CI) record?
- It ensures all team members are trained in configuration management.
- It helps track changes, relationships, and attributes of configuration items.
- It's a formal document of no real value.
- It's only required for large organizations.
Maintaining Configuration Item (CI) records is crucial in Configuration Management. These records track changes, relationships, and attributes of CIs, enabling effective control and traceability throughout the SDLC.
Which software maintenance model is focused on addressing and fixing known errors or issues in a software product?
- Adaptive Maintenance
- Corrective Maintenance
- Perfective Maintenance
- Preventive Maintenance
Corrective Maintenance is centered on fixing known issues and errors in software. It is one of the key aspects of software maintenance. Other models address different aspects of maintenance.
Which of the following best describes the process of Test-Driven Development (TDD)?
- Skip testing altogether
- Write code first, then test
- Write tests first, then code
- Write tests only when necessary
TDD involves writing tests before writing the actual code. These tests are meant to define the expected behavior of the code, and developers implement the code to meet these predefined expectations.
