I didn't have to search Google or watch YouTube videos. When I started working with this tool, we just had to do the initial assessment about whether this tool will be able to support our daily work or not. It is user-friendly and easy to understand because they have created so many useful functionalities. They have always helped me within a short duration of time." "The most valuable feature is the ability to execute parallel requests, unlike JMeter and LoadRunner which can only be run sequentially." "Simple capturing of dynamic variables and simple scripting." "The licensing cost is very less for NeoLoad. Also, the tool’s help center is very responsive and helpful. This post was originally published in 2018 and was most recently updated in July 2021."I like the solution’s performance and integration. You can find the full installation and detailed breakdown here: Install the WAN emulation. The WAN emulation function, as a whole, provides the complete simulation and emulation that saves expensive overhead from having to create real WAN users for testing and provides detailed feedback of the experiences given to your users within those environments. The NeoLoad Cloud services offer ready-to-use Linux machines with the WAN emulation function already implemented.įor complete installation instructions by OS, please refer to our documentation to Install on Windows, OS X, or Linux. Note: Because installing the WAN emulation driver on a Linux system may be troublesome, the NeoLoad Cloud services may be used for on-the-spot tests. It’s also important to point out that when installing a controller on Windows (provided the Windows version is supported), the WAN emulation driver is automatically installed with it. Linux is supported with versions 2.6, 3.10, 3.14 and 4.1. Connection speed simulation is supported on OS X, but not packet loss nor latency. On Mac OS X there is no WAN emulation driver to install. For example, WAN emulation is not supported for Windows OS versions 10 and higher and Windows 2016. Requirements by OS to install WAN emulation varies. The WAN emulation feature is cross-OS compatible, working on OS X, Linux, and specific versions of Windows. Note: WAN emulation will not work on an IPv6 configured server. The WAN emulation driver itself must be installed on the network interface card’s location of the load generator, or the controller’s installation, or the load generator agent’s Installation. Here you see an actual NeoLoad reporting result and how it quickly displays the differences in network speed, and impact on the overall performance of your application over time: Thus your user path script has been pushed through a complete simulation of two cell phone types. Now, what if we compare the same script being run through a 3G mobile device? At the end of a test, the results comparatively and usefully display the full experience each type of user has emulated. Here you can see what the 4G latency would look like. NeoLoad automatically provides the adjustments and calculations needed for this emulation. Or perhaps the difference between a 3G network vs. Their latency would be different, wouldn’t it? Even with an optimized content delivery network driving the website, there is still going to be “user” latency, and emulating the percentage of this for groups A through E is a smart way of addressing this with packet loss and additional latency extended further and further in each group as the tactic. Let’s say you have a project that requires 500 virtual users visit a website from five different continents in the world. We have covered the options available within the WAN emulation dialogue, so let’s describe a real-world scenario that would utilize it. It’s important to realize that WAN emulation is additional latency added to real lag. The above dialogue allows you to configure exactly how much the upload/download latency is and what percent of packets are dropped. Clicking on a simple picker button allows you to pick and choose which profile will make sense to test against:īy using the WAN emulation feature in a test, you can simulate degraded network conditions, networks with latency issues, and packet loss percentages. We have this problem solved! The WAN emulation feature in Tricentis NeoLoad enables you to realistically re-create conditions of an existing IT or mobile network with simulated bandwidth values, latency levels, and packet loss rates. Not testing these applications across simulated network speeds increases the possibility of performance issues. Many organizations deploy new applications for their users without testing network virtualization.
