How does Equivalence Partitioning play a role in Black Box Testing?
- It helps identify invalid inputs
- It focuses on specific inputs
- It tests only functional requirements
- It is not relevant to Black Box Testing
Equivalence Partitioning is a Black Box Testing technique that divides the input domain into equivalence classes, ensuring that the test cases represent different valid and invalid partitions. This helps to identify specific inputs for testing and ensures comprehensive coverage.
What is the main objective of regression testing in the software development life cycle?
- To verify new features
- To identify defects in the initial code
- To ensure that new code changes do not introduce new defects in existing functionality
- To improve code performance
The main objective of regression testing is to ensure that new code changes do not introduce new defects or issues in the existing functionality of the software. It helps maintain the overall quality and reliability of the software.
Which software evolution model is focused on re-creating a system from scratch?
- Waterfall Model
- Incremental Model
- Spiral Model
- Big Bang Model
The Big Bang Model focuses on re-creating a system from scratch. It's a risky approach where the old system is entirely replaced with a new one.
The ______ model of software quality assurance involves both verification and validation activities.
- Waterfall
- V-Model
- Agile
- Spiral
The V-Model of software quality assurance integrates both verification and validation activities into the software development life cycle. It is a structured approach that emphasizes the relationship between development phases and corresponding testing phases.
In Agile methodologies, regression testing is often automated to facilitate continuous integration throughout the development process.
- Documentation
- Integration
- Planning
- Testing
In Agile methodologies, automated regression testing is a key component of continuous integration, allowing for frequent and automated testing as new code is integrated, ensuring that changes do not introduce defects.
How might a complex, interdependent software system pose challenges for effective Unit Testing, and what strategies might be employed to mitigate these challenges?
- Complex systems make Unit Testing easier
- Interdependencies have no impact on Unit Testing
- Complex, interdependent systems may require extensive mocking and stubbing
- Complex systems eliminate the need for Unit Testing
In complex, interdependent systems, unit testing can be challenging due to the dependencies on other units. To mitigate these challenges, extensive mocking and stubbing may be required to isolate units for testing. These techniques help create controlled environments for unit testing.
Which type of software maintenance deals with fixing bugs and errors after the software has been deployed?
- Corrective Maintenance
- Adaptive Maintenance
- Perfective Maintenance
- Preventive Maintenance
Corrective maintenance, also known as bug fixing, addresses and fixes errors, defects, or issues that occur after the software has been deployed. It is aimed at ensuring the software functions correctly.
_____ testing in UI design involves evaluating a product by testing it on users to directly observe and analyze how they use it.
- Usability
- Functionality
- Regression
- Performance
Usability testing in UI design is a crucial process where a product is evaluated by testing it on actual users. This allows designers to directly observe and analyze how users interact with the interface, providing insights into areas of improvement to enhance the user experience.
Imagine a situation where a software application processes data through several interrelated algorithms. How might white box testing be applied to validate the accuracy and efficiency of these algorithms?
- By only examining the input data
- By testing the software without any knowledge of its internal structure
- By inspecting and testing the code and internal logic of the algorithms
- By relying solely on user feedback
White box testing, in this context, involves examining and testing the internal code and logic of the algorithms to ensure their accuracy and efficiency. It requires knowledge of the application's internal structure.
______ maintenance is required to rectify defects and errors that were not discovered during the earlier stages of the development cycle.
- Corrective
- Adaptive
- Preventive
- Perfective
Corrective maintenance focuses on fixing defects and errors that were not identified during development or testing phases. It is essential for ensuring the reliability and stability of the software.
Which software architecture style divides an application into interconnected components that can be developed independently?
- Monolithic
- Microservices
- Client-Server
- Service-Oriented
Microservices architecture is an architectural style that divides an application into smaller, interconnected components that can be developed independently. Each microservice is responsible for specific functions and communicates with other services over a network. This approach enhances flexibility, scalability, and ease of development.
In the context of the Strategy design pattern, strategies are often implemented using _____?
- Inheritance
- Composition
- Polymorphism
- Encapsulation
In the Strategy design pattern, strategies are often implemented using composition. This allows different strategies to be encapsulated in separate objects that can be switched at runtime, promoting flexibility and modularity in the software design.
