In TDD, what is typically written before the actual code implementation?
- Design specifications
- Documentation
- Tests
- User manuals
In Test-Driven Development (TDD), tests are typically written before the actual code implementation. Writing tests first guides the development process and ensures that the code meets the expected behavior defined by these tests.
In TDD, what does the term "mocking" refer to?
- Creating a fake user interface for testing purposes.
- Generating random test data to evaluate system robustness.
- Intentionally introducing defects to assess error-handling capabilities.
- Simulating the behavior of objects or systems that the tested code interacts with, enabling isolated unit testing.
In TDD, "mocking" involves simulating the behavior of objects or systems that the tested code interacts with. This allows for isolated unit testing, ensuring that the focus is on the specific code being tested rather than external dependencies.
Which NoSQL database is designed for high availability and partition tolerance?
- Apache Cassandra
- CouchDB
- MongoDB
- Redis
Apache Cassandra is designed for high availability and partition tolerance, making it suitable for distributed and fault-tolerant systems. It follows the principles of the CAP theorem.
What is the primary function of Azure Blob Storage?

_______ is an architectural style for designing networked applications.
- JSON
- REST
- SOAP
- XML
REST (Representational State Transfer) is an architectural style for designing networked applications. It emphasizes a stateless client-server communication model, scalability, and a uniform interface. RESTful APIs are built based on these principles.
The Strategy design pattern defines a family of _______ algorithms and encapsulates each one, making them interchangeable.
- dependent
- interchangeable
- nested
- related
The Strategy design pattern defines a family of interchangeable algorithms. It allows a client to choose from a family of algorithms and gives them the flexibility to interchange algorithms without altering the client code.
What is the primary purpose of responsive web design?
- To ensure a consistent user experience across various devices and screen sizes
- To focus only on desktop users
- To make web pages load faster
- To use only fixed layouts for web pages
The primary purpose of responsive web design is to ensure a consistent and optimal user experience across various devices and screen sizes. This approach allows websites to adapt to different resolutions and orientations.
