What is a Test Case in Computer Science?

📚 Quick Study Guide

• 🧪 A test case is a specific set of conditions and inputs designed to verify that a software application or system is functioning correctly.
• 📝 Each test case includes input data, expected output, and preconditions.
• ✅ The goal of a test case is to determine if the software meets the specified requirements and functions as intended.
• 🐞 Test cases help identify bugs, errors, or defects in the software.
• 📈 Test cases should cover various scenarios, including positive, negative, and boundary conditions.
• 🔑 Test cases are derived from requirements documents, design specifications, and user stories.
• 💡 Effective test cases are clear, concise, and easily repeatable.
