What is the difference between scalability and performance testing?

Scalability testing evaluates how well a system can grow and handle increased loads, while performance testing measures the system's speed and responsiveness under various conditions.

Can you give me examples of each type of testing?

Sure! For scalability testing, you might simulate a sudden increase in user traffic to see if the system can handle it. For performance testing, you could measure how quickly a page loads under normal conditions.

Why is scalability testing important for web applications?

Scalability testing is crucial because it ensures that your web application can accommodate growth, preventing crashes and maintaining user satisfaction as demand increases.

How often should I perform these tests?

It's recommended to perform scalability and performance testing regularly, especially before major releases or when significant changes are made to the application.
