Software Quality Assurance Practice Exam

What does the concept of "extreme unit testing" emphasize?

1. Short development cycles

2. All code must have unit tests before coding begins

3. Integration of multiple teams

4. Post-release testing

The correct answer is: All code must have unit tests before coding begins

The concept of "extreme unit testing" emphasizes that all code must have unit tests before moving forward with development. This approach aligns with the principles of Extreme Programming (XP), which is a methodology that promotes frequent releases in short development cycles. By requiring unit tests to be created prior to the actual coding process, it ensures that developers maintain a high level of code quality from the start. This practice encourages test-driven development (TDD), where the design and implementation of code are driven by test cases, fostering a robust and reliable codebase. While other options may relate to software development practices, they do not encapsulate the core principle of "extreme unit testing." For example, while short development cycles are characteristic of Agile practices, they do not inherently relate to the strict testing criteria established in extreme unit testing. Similarly, integration of multiple teams and post-release testing are essential components of the software development lifecycle but do not specifically address the foundational aspect of unit testing before coding begins, which is crucial in the extreme unit testing context. This focus on preemptive unit tests is what sets extreme unit testing apart in the realm of software quality assurance.
