A _____ in Unit Testing is a condition or exception that a unit of code must handle correctly.
- Unit case
- Test suite
- Unit scenario
- Test condition
In Unit Testing, a "unit scenario" is a condition or exception that a unit of code must handle correctly. These scenarios are designed to test specific aspects of the code's behavior, ensuring that it behaves as expected under various conditions.
What role does software maintenance play in enhancing customer satisfaction and user experience?
- It has no impact on customer satisfaction.
- It can lead to more bugs and issues, decreasing satisfaction.
- It addresses user concerns, improves reliability, and adds features, increasing satisfaction.
- It only focuses on fixing minor bugs.
Software maintenance is crucial for addressing user concerns, enhancing the reliability of the software, and adding new features that can significantly improve customer satisfaction and the overall user experience. This, in turn, can lead to increased customer loyalty and positive reviews.
What is the primary purpose of utilizing software quality metrics in a project?
- To increase development speed
- To reduce project costs
- To measure the progress of the project
- To improve the quality of the software
The primary purpose of using software quality metrics in a project is to improve the quality of the software. These metrics help identify issues and areas for improvement, which, in turn, can lead to a higher-quality end product.
______ maintenance involves making functional enhancements to the software without disturbing its existing functionalities.
- Corrective
- Adaptive
- Perfective
- Preventive
Perfective maintenance involves making functional enhancements to the software without disturbing its existing functionalities. It aims to improve the software by adding new features or enhancing existing ones.
Which phase of the SDLC comes after the implementation and maintenance of the system?
- Requirements Analysis
- Testing
- Implementation
- Maintenance
The maintenance phase of the SDLC comes after the implementation phase. During maintenance, the software system is updated, improved, and adapted to changing needs and requirements.
Which factor is critical in determining the cost of software maintenance?
- Software development methodology
- Software architecture
- Size and complexity of the software
- Team communication skills
The size and complexity of the software are critical factors in determining the cost of software maintenance. Larger and more complex software systems typically require more effort and resources to maintain.
What does the reliability quality attribute signify in the context of software?
- Speed of the software
- Security of the software
- Trustworthiness and consistency of the software
- Adaptability of the software
Reliability, in the context of software, signifies the trustworthiness and consistency of the software. A reliable software system performs its functions consistently and without unexpected failures, providing a dependable user experience.
RESTful APIs use HTTP requests to POST, READ, PUT, and DELETE data, often referred to as ______ operations.
- Update
- Edit
- Modify
- Update
In RESTful API design, these operations are often referred to as "CRUD" operations, which stands for Create, Read, Update, and Delete. The "Modify" operation corresponds to the "Update" operation in CRUD.
In a context where a software system is expected to store and manage highly sensitive user data, how would the security attribute be defined and assured throughout the development process?
- Security is not necessary when dealing with sensitive data
- Security should be a one-time implementation
- Security must be a continuous concern throughout development
- Security is the sole responsibility of users
In this context, security must be a continuous concern throughout the development process. Sensitive user data requires robust security measures, including encryption, access controls, and vulnerability assessments. Security must be implemented from the project's start and maintained as threats evolve.
Which design pattern restricts the instantiation of a class to a single instance and provides a global point of access to it?
- Factory Pattern
- Singleton Pattern
- Observer Pattern
- Abstract Factory Pattern
The Singleton design pattern restricts the instantiation of a class to a single instance. It provides a global point of access to that instance, making it useful when you want to ensure there's only one instance of a class throughout your application, like a configuration manager, a database connection, or a logging service.
