Testing Popup Windows
We often receive questions about how Load Tester handles popup windows. In this post, I’ll describe how Load Tester handles these elements and provide a sample recording.
How does Load Tester Handle Popups?
Users do not regularly encounter popups. As a result, these windows may appear to function differently from regular browser windows.
However, when recording using a virtual browser, Load Tester records any calls to the server. Replaying a recording or running a test will replay those calls whether issued from a normal browser window or a popup.
NOTE: The following method is only applicable to “Virtual Browser” recordings.
Recording a Popup Window

Generating Load from Multiple Regions – Load Tester 6.6
Load Tester’s cloud load generation feature includes the ability to use datacenters located in different geographical regions.
This post contains detailed steps for adding an Amazon EC2 account and for running a new test configuration. These instructions apply to Web Performance Load Tester 6.6 and up. For Load Tester 6.5 and earlier, see Generating Load from Multiple Countries – Load Tester 6.5.
Why Load Test From Multiple Regions?
Generating load from different regions enables more realistic load tests. Rather than using just local datacenters, tests can simulate traffic from all over the world rather than just local datacenters.
This feature also allows testing … Continue reading »

Mail Server Load Testing
Mail servers can be load tested by sending a large number of emails to a mail server over a specific period of time and recording how the server behaves as it receives those connections. Organizations may require this type of load testing for several reasons. For example, they generally receive a consistent, low level of mail traffic with intermittent periods of high traffic. They may also expect growth within a certain period of time and want a mail server that is capable of scaling with the organization’s growth.
REST/Web Services and API Load Testing
In this post, I’ll discuss why API testing is important, a typical situation that a tester might experience, and how to perform API testing with Web Performance Tester.
How to Change Recorded Hostnames/Edit Recorded URLs
Web Performance Tester offers several tools for changing recorded hostnames. Below, I describe common situations users may experience, and the appropriate method of changing datasources for each.
Load Tester 5.4 Released!
Our goal with Load Tester 5.4 was to build the easiest to use load testing tool, even if you had no experience with load testing. It should just make sense when you look at it, with every button in the right place and all of the right information at your fingertips. We’ve spent most of 2013 reworking the user interface, trying out several different ways of doing the normal load testing workflow, until it both looked great and let us get load testing done as quickly as possible.
But of course, user interface improvements weren’t the only changes: we threw in … Continue reading »
Scheduling Load Tests with Load Tester 5.4
Many of our customers want to run tests off-hours to minimize collateral inconveniences. For example, if the rest of your QA team is working on the same test server as you, it might behoove you to run a load test at 2:00 AM when the team is asleep. Load Tester has had the ability to schedule off-hours tests for years, but the feature remains a frequently asked question among potential testers.
In Load Tester 5.4’s streamlined user interface, you can schedule a test from the ‘Control’ menu by choosing “Schedule Load Test.” A “Scheduled Operation” dialog will appear, and you can … Continue reading »
How Much Bandwidth Do You Need To Do a Load Test?
One of the common questions people are interested in is finding out how much a test is going to cost. There are a lot of factors that go into this equation, such as getting an appropriately sized testing license, configuring a test server environment, reserving hardware for Load Engines, and bandwidth costs between the Load Engines and the content delivery servers (such as a CDN or origin servers). Let’s take a look at just how we might calculate the bandwidth charges that are involved in a single test.
If your site is only needs to support a few hundred users, then … Continue reading »
Measuring Web Page Load Times using JMeter
At last count there were over 65 separate commercial load testing tools out there, but few with the name recognition of the open source program JMeter. Often people will call us up and ask to compare Load Tester with JMeter, but I only had a cursory look at it many years ago, and couldn’t speak from recent first-hand knowledge. So, when someone called me last week asking about JMeter, it seemed like a good opportunity to give it another look.
