LoadStorm is an on-demand load and performance testing tool that utilizes Amazon Web Services for massive scalability. It is a web application that allows developers and testers to generate large volumes of virtual user HTTP traffic against a target server application. Rather than providing a million features, the design goal of LoadStorm is to make load testing as scalable and cost-effective as possible. Product Introduction: Many web application developers don’t need the complexity built into traditional enterprise software solutions (e.g. LoadRunner). Most cannot afford the license fee for those solutions anyway. Open source tools are priced right, but it still […]

There are 3 primary functions that you need to consider when load testing your web application: Build a test plan – define the traffic behavior Run a test – define how much, duration, schedule Analyze the test results – view the reports LoadStorm’s user interface presents each of these to you by clicking on a tab at the top of the page. Build a Test Plan A test plan is what tells LoadStorm the VUser activities to simulate. When you run a load test, you must choose one of your plans. This plan is defined by scenarios which represent […]

LoadStorm has an example load test plan for you to try. It is an easy way to learn LoadStorm because you don’t have to create test scenarios – you simply use one we have created for you. Our built-in example provides a very quick way to run a load test and see some results. It simulates browsing through a static web site installed on Amazon’s S3. The content of the site is publicly available information from the CIA. First, you copy the example. Go to the home page. Click on Copy Example button Select the radio button next to CIA FactBook.

We created a brief video that shows the main screens in our load testing tool. The video explains the primary navigation and what features are available on each tab. The application has a Build tab where you can create test plans. Plans contain scenarios, and scenarios contain steps. Each test scenario corresponds to a type of user on your site. For example, you may create a test plan with 3 scenarios: Login and post comments Anonymous browsing of a product catalog Shopping cart experience with credit card purchase Each of these scenarios can be assigned a value to control the […]

We beg our customers to consider iterative load testing cycles that begin with small volumes your web application can handle easily. Then, gradually increase the peak volume in subsequent test cycles until you find the breaking point. Occasionally a test will be terminated early because the target server fails. There is a STOP TEST button on the page for a running test, and sometimes a customer will press the button because the Error Rate and Response Times indicate a failure condition – there is no need to continue the test. The test didn’t reach the Peak VUsers scheduled. When this happens […]
