Difference Between Manual and Automated Testing (Simple)

📚 Quick Study Guide

🔍 Manual Testing: Testing software by hand, without using any automation tools. A tester executes test cases manually, observing the behavior and noting the outcomes. It's often used for exploratory testing and usability testing. 🧪 Automated Testing: Testing software using automation tools and scripts. It involves writing test scripts that execute automatically, comparing the actual results with the expected results. It's ideal for regression testing and performance testing. ⏱️ Speed: Automated testing is much faster than manual testing. 💰 Cost: Initially, automated testing requires more investment (tools, training) but can be more cost-effective in the long run. 🎯 Accuracy: Automated testing is less prone to errors compared to manual testing. 🔁 Repetitive Tasks: Automated testing is perfect for repetitive tasks, while manual testing is better for ad-hoc or exploratory testing. 💡 When to use Manual Testing: When testing usability, exploratory testing or ad-hoc testing. ⚙️ When to use Automated Testing: When conducting regression testing, performance testing, or load testing.
