Traditional SDLC models often face the limitation of ______ when dealing with changing requirements.
- Adaptability
- Lack of planning
- Limited documentation
- Rigidity
Traditional SDLC models often face the limitation of rigidity when dealing with changing requirements. These models often have well-defined phases and may struggle to accommodate changing requirements, making them less adaptable.
What is the main objective of performance testing in software development?
- Ensure 100% code coverage.
- Identify and fix all defects.
- Validate user interface design.
- Verify if the software meets specified performance criteria
The main objective of performance testing is to verify if the software meets the specified performance criteria, such as response time, scalability, and resource utilization. It helps ensure the software's performance is acceptable.
The process of tracing and identifying the origin of requirements is facilitated by the use of a __________ matrix.
- Requirements
- Stakeholder
- Traceability
- Validation
Traceability matrices are used to trace and identify the origin of requirements. They help ensure that each requirement is linked to its source and that nothing is missed during the development process.
Imagine a scenario where a user identifies a bug in a mobile application and reports it through the app's feedback system. What steps would typically follow in the bug tracking and resolution process?
- The bug is documented and prioritized.
- The bug is fixed immediately.
- The bug is ignored by the development team.
- The user is asked for payment.
Bug tracking and resolution typically involve documenting the reported bug, prioritizing it based on its impact and severity, assigning it to a developer, fixing it, testing the fix, and then releasing an update. Ignoring or asking for payment is not standard practice.
The _____ SOLID principle emphasizes that high-level modules should not depend on low-level modules, but they should depend on abstractions.
- Dependency Inversion
- Interface Segregation
- Liskov Substitution
- Open-Closed
The Dependency Inversion SOLID principle states that high-level modules should not depend on low-level modules; both should depend on abstractions. This promotes the use of interfaces or abstract classes to achieve this separation of concerns, enhancing maintainability and flexibility in the software.
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.
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.
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.
Which limitation of SDLC is highlighted by the need for extensive documentation in every phase?
- Excessive emphasis on user involvement.
- Lack of flexibility and adaptability.
- Lack of structure in SDLC.
- Potential for scope creep.
The extensive documentation requirement in traditional SDLC models underscores the limitation of rigidity and lack of adaptability to changing project needs, making it challenging to manage evolving requirements.
How do tools like Selenium WebDriver facilitate automated testing in software development?
- They automate the entire software development process.
- They only work with Java applications.
- They provide a framework for automating web application testing.
- They require manual test case creation.
Selenium WebDriver is a tool that provides a framework for automating web application testing. It allows testers to write test scripts in various programming languages and automate the testing of web applications across different browsers.
