Load testing with WAPTpro

Load testing is one of several different kinds of Performance related tests (Load Testing, Stress Testing, Spike testing, Endurance testing, Scalability Testing, Volume testing). In a sense of usage all of them are related to Performance Testing definition, which in one sentence, would be:

“Performance Testing is artificially creating or simulating load and measuring how your environment handles it.”

Load testing provides system monitoring by increasing the load. You can test how the system performs under higher load, but also under base or expected load. During Load Tests you can monitor response times, throughput, server condition and much more.

The goal of Load Testing is not to break the target environment, but to measure performance parameters under high load.


WAPTpro is one of several Load testing tools that can be used for this purpose. It provides interface for testing performance parameters of a websites and web-based internet applications.

Create Scenario

To perform Load testing for a website with WAPTpro, first you need to create a test Scenario with general parameters for the test: number of virtual users, type of load, test duration or the total number of sessions for all virtual users. This can be obtained in Scenario Wizard that you can open by click on a New button in a upper left corner of the WAPTpro window. Later, these settings can be changed by clicking on a Test Volume menu item in a left section of WAPTpro window.

Mobile Website Load Testing

Internet usage on mobile devices increases every year. Even though mobile screens became bigger, its size is still significantly smaller than PC monitors. As the result the website won’t appear correctly or the content will be too small. Because of that the websites needs to be adjusted for the current device. For this purpose there is usually created a mobile version of the website. These changes can cause different performance and stability issues. That’s why there is a need for testing on those pages as well.
There is a variety of devices and web browsers. The website to identify from what device/browser the request came from it will check the “User agent” header string which contains this information. In the later part we will show an example of the header.

For the load test we will be using JMeter. You can download the newest release from here: Download JMeter
