Summary
In this chapter, we explored the skill of unit testing, from its fundamental importance to mastering its practical application with Python’s unittest and pytest frameworks. We expanded our skills by exploring intermediate concepts, such as parameterized, performance, and scenario testing, and concluded with a practical guide to tackling unit testing questions in job interviews.
As we transition into the next chapter, we’ll move from the coding realm to the data world, focusing on essential knowledge of databases and their operation. This shift will further enrich your data engineering skills, providing the necessary tools to interact with, manipulate, and manage data effectively in your future roles. Let’s continue our journey into the heart of data engineering.
