  Before this reading, I mostly thought about becoming a “good developer” in terms of technical skills, knowing more languages, frameworks, and tools, and use them according to what was needed to reach the goal. However, the book shifts focus on identity and long-term growth. It argues that being a Software Craftsman is not just about competence; it is about commitment to mastery. The three stages—apprentice, journeyman, and master—made the abstract idea of growth feel structured and personal. I strongly identify with the apprentice stage. The idea that everyone begins with “Hello World,” but what differentiates people is how they approach growth afterward, really resonated with me. The journeyman stage was interesting because it expands responsibility outward. It is not enough to just improve personally; you begin contributing to others and strengthening the community. But something interesting is that reality of modern software development is that you may be with a single tea...

  The article “JUnit Testing: The Basics and a Quick Tutorial” explains the fundamentals of Junit and how it works in testing environment. The author begins by describing unit testing as the process of verifying small pieces of code independently, ensuring each component behaves correctly before integrating it into a full application. JUnit supports this by allowing developers to write automated tests using annotations and assertions that compare expected and actual results. The article highlights that testing early improves code quality, helps detect bugs quickly, and supports continuous integration workflows. It also introduces major features such as annotations, assertions, parameterized tests, and exception testing. Finally, the tutorial demonstrates how to install JUnit, write a simple test class, and run tests from an IDE or command line. I selected this resource because I am currently learning software testing and writing unit tests myself. This article is short but sum...
