LoadRunner VUDs Are Back! Kind of…

VUDs are back

This news is hot off the press, LoadRunner VUDs are back, albeit with a couple of minor changes – one of which is the name. This is great news for new and existing LoadRunner customers and performance testers, with OpenText bringing back the incredibly useful flexibility that VUDs provided.

The new version of VUDs, known as LoadRunner Virtual User Flex Days (VUFDs), allows you to buy Vusers by the day. They can be used with permanent Vuser licenses or on their own.

Currently, VUFDs are available for on-premises installs of LoadRunner Professional and LoadRunner Enterprise. However, I would be prepared to make a bet that they’ll be available for LoadRunner Enterprise on SaaS before too long.

Why Are VUFDs So Useful?

VUFDs are a great option in multiple load-testing scenarios. A few of these are highlighted below:

  • Ramping Up: If you have a relatively low number of Vusers but needed a few days of peak testing. Say you have 250 permanent Vusers, which satisfy most of your needs. But occasionally you need to test peaks with 1,000 Vusers. VUFDs can provide the extra 750 Vusers, topping your supply up to 1,000 Vusers.
  • Infrequent Testing: They are also handy for project-level performance testing, and beneficial if you only execute performance testing a few times a year.
  • Additional Protocols: VUFDs are also great if you want to occasionally test additional protocols. For example, you might regularly test web applications, but every now and again you want to test an ERP. Buying permanent ERP Vusers is a big commitment, but ERP VUFDs are a more affordable option in this case.
  • Testing Service Providers: If you provide Performance Testing services to your customers, they are great as an engagement licence.

VUFDs support the widest range of applications and technologies and are therefore great for performance testing pretty much any application. They can be bought in different quantities, with built in discounts the more you buy.

They are essentially the same product as VUDs, with the flexibility you loved, but now also include product support.

Here’s an example of how VUFDs work

  • Let’s say you buy 1000 VUFDs
  • Then, one day you run multiple tests with up to 250 Vusers
    • Your 250 VUFDs can be used however you need for 24 hours, across as many tests as you like. Multiple tests to 250 users or one look soak test.
    • This activity uses up 250 VUDs
    • At the end of the 24-hour period you have 750 VUDs left
  • Another day, you run a test with 500 Vusers
    • Your 500 VUDs can be used however you need for 24 hours, across as many tests as you like
    • This activity uses up 500 VUDs
    • At the end of the 24-hour period you have 250 VUDs left
  • And so on, until you have no VUDs left

the next generation of test tools

The Evolution of Test Tools: Passing the Baton

Test tools have long been essential to software quality and testing efficiency, but over the years, they have transformed significantly, becoming more powerful, cost-effective, and reliable than ever before. One test tool suite has been at the forefront of this evolution, tracing its lineage back to the 1990s.

Service Virtualization

Seriously, Why Aren’t You Using Service Virtualization?

Service Virtualization (SV) remains one of the most criminally underused tools in software testing. It’s astonishing to me just how many organisations still ignore its benefits – test earlier and save money. If you’re not using SV, you are missing out—plain and simple.

UFT Digital Lab

UFT Digital Lab 24.2: What’s New?

If you need to test multiple devices, OS versions, or browser types, you need UFT Digital Lab from OpenText (previously known as Mobile Center and UFT Mobile). It has a comprehensive suite of features specifically designed for mobile, tablet and web testing across myriad platforms.

VSM Building Blocks

VSM is Easy with ValueEdge from OpenText

Value Stream Management (VSM) can revolutionise your business, driving customer value and removing unnecessary costs and investments. However, it does require a rethink of internal processes and culture, which can be a daunting prospect.

Unlock Value with VSM: The Crucial Role of Software Testing

Delivering high-quality solutions is an essential part of Value Stream Management (VSM). After all, substandard solutions don’t deliver value to customers or shareholders. That’s why software testing is a central component in VSM, and it’s now easier than ever with the powerful and user-friendly OpenText ValueEdge testing tools.

VSM: Reduce Project Costs The Right Way

It’s hard for businesses to understand where their investments are going and whether they will translate to business and customer value, especially when it comes to software development…. This is where VSM comes in.

AI the unseen software development partner

AI: The Unseen Partner in Modern Software Engineering

Within software projects, AI (and ML) is increasingly used in areas including code generation, test automation, and project management, although many of these uses are often not in an officially sanctioned capacity. Where ChatGPT is a bit of a Jack-of-all-trades, enterprise AI solutions are far more targeted, and far more robust.
