📚 Quick Study Guide

• 🔍 Definition: Test cases are a set of conditions or variables under which a tester will determine whether a system satisfies requirements or works correctly.
• 📝 Purpose: To ensure software quality by verifying that each feature works as expected.
• 🧪 Basic Components: Test case ID, test case name, preconditions, test steps, expected results, actual results, and pass/fail status.
• 💡 Black Box Testing: Testing without knowledge of the internal workings of the application. Focuses on input and output.
• ⚙️ White Box Testing: Testing with knowledge of the internal workings of the application. Involves testing code paths and logic.
• ✅ Positive Testing: Testing with valid inputs to ensure the application behaves as expected.
• ❌ Negative Testing: Testing with invalid inputs to ensure the application handles errors gracefully.
