You can use the results to drill down into specific virtual user sessions to diagnose problems. With minimal scripting, you can quickly record specific actions and replay them across tens of thousands of real browsers. LoadNinja makes it easy to create browser-based load tests using a record and playback process. While it's more resource-intensive to spin-up actual instances of browsers, the rise of cloud computing has lowered these costs over time - and it's now an affordable option. For example, Apache JMeter doesn't actually perform browser tasks, such as rendering HTML or executing JavaScript, so these timings aren't included in the performance test results.Д«rowser-based tests incorporate these browser timings into the performance testing results to paint a more complete picture. The problem with protocol-based tests is that they don't test anything beyond the server response.

Many applications that required load testing were thick clients that could only be accessed via thick clients.Load testing is often outsourced to third parties on an infrequent basis to verify performance.Hardware is expensive and protocol-based tests are highly efficient using tools like Apache JMeter.There are several reasons for taking this approach: For example, you might use Apache JMeter to send tens of thousands of requests to a REST API server and analyze the response times, error rates and other performance metrics.

Conventional load testing involves simulating traffic by creating a load at an API or protocol level.
