🔍 What is Load Testing?

Load Testing is a type of non-functional testing that evaluates how a software application performs under an expected user load. It helps identify performance bottlenecks, system scalability, and stability before deployment.

💡 Why is Load Testing Important?

• Prevents system crashes due to high traffic

• Identifies performance issues before release

• Improves user experience and reliability

• Saves businesses from financial losses due to downtime

📌 Key Aspects of Load Testing:

✅ Determines max operating capacity

✅ Evaluates infrastructure sufficiency

✅ Tests application sustainability under peak loads

✅ Identifies server, database, and network limitations

⚡ Real-World Examples:

🚀 E-commerce failures during major sales events

✈️ Airline website crashes due to high traffic

📚 Online encyclopedia overwhelmed by free access promotion

🔧 Load Testing Strategies:

🔹 Manual Load Testing

🔹 Open-source & Enterprise-class Tools

🔹 In-house Developed Tools

🛠 Popular Load Testing Tools:

🔹 LoadRunner

🔹 Apache JMeter

🔹 Gatling

📊 Load vs. Stress Testing:

🔸 Load Testing checks system performance under expected workloads

🔸 Stress Testing pushes the system beyond limits to find breaking points

✅ Advantages of Load Testing:

✔️ Prevents downtime & improves performance

✔️ Enhances scalability & reliability

✔️ Reduces failure costs & increases user satisfaction

Ignoring Load Testing can lead to huge financial losses and damaged reputations—test before it’s too late! 🚀
