CST438: Week 2 Journal

A Mock is a simulated object that mimics the behavior of real objects in a controlled way, primarily used in unit testing to isolate the code being tested from external dependencies like databases or APIs. Mocks are useful because they allow developers to specify how these objects behave, enabling focused testing of the code's logic without interference from real external factors. This control enhances test performance by avoiding time-consuming operations, simplifies testing by making it easier to simulate various conditions, and provides verification of how dependencies are interacted with. Ultimately, mocks facilitate better testing practices, leading to more reliable and maintainable code.

CST438 Week 6 Journal

This week i learned about Service-Oriented Architecture (SOA) and its significant impact on modern software development. I learned that SOA promotes the creation of independent services that can communicate over a network, enhancing interoperability and system flexibility. This architecture allows for better scalability, as services can be independently updated and reused across different applications. However, I also recognized the challenges associated with SOA, such as increased complexity and the need for effective data management and governance. Overall, understanding SOA has given me valuable insights into designing systems that can adapt to changing business needs while optimizing resource utilization.
