Introduction to performance testing at the NWTG

I really enjoy the NWTG events in Manchester which arintro_nwtge great for the testing community in this area.  I’ve noticed that performance testing is “under represented” at these events (which frequently
have a functional-testing bias).  With this in mind, I tried to give an introduction to performance testing.

For those unable to attend, the slides are available on SlideShare.

….and a video of the presentation is available on YouTube.
(My son thinks that the number of “ums” and “erms” is hilarious. I’m hoping to reduce the number of these “linguistic fillers” for my next presentation)

The final slide includes links to the Trust IV LoadRunner download page as well as blogs that I have found helpful during my time as a tester.

If anybody wants to learn more, don’t hesitate to contact @RichardBishop or @TrustIV via Twitter.

What’s new in LoadRunner 12?

LoadRunner 12

The roadmap for LoadRunner 12 was presented at HP Discover Barcelona in December last year. Since that time, I’ve been lucky enough to have a beta copy of LR12 for evaluation purposes. Now that the product has been released, I’m able to share some of the new features that I’ve found to a wider audience.

Key observations / new features are:

Cloud-based load generators. HP describes this feature as “cloud bursting”. Users now have the ability to provision load generators on AWS (Amazon Web Service) cloud servers from within LoadRunner or Performance Center. As well as this, the ports used to communicate between LoadRunner components such as Load Generators, Controllers, MI Listeners are user configurable through the new “network security manager” tool. This simplifies the setup process and allows more flexibility in distributed test networks or cloud-based test environments.  It is even possible to configure different ports/proxies for each Load Generator.

Licensing – 50 vUsers free
We in the user community have been asking for this for a long time. Providing fully-functional applications that allow small-scale testing allow prolonged evaluations and proof-of-concept exercises. This is great, because it allows more people e.g. developers to get hands-on experience and see the potential benefits of using LoadRunner.

This is likely to improve the adoption rate for LoadRunner and prevent the erosion of market share to low-cost / no-cost providers of performance testing software.

All protocols are included in the “community edition” license, with the exception of GUI (UFT) and COM/DCOM protocols as well as those protocols in the “template” bundle (i.e. those vUser types whose scripts are manually created (rather than record/replay) such as C# .Net, VB .Net vUsers).

VUGEN improvements
There are a variety of improvements as you would expect. Key ones are:

  • The ability to review replay statistics for tests after each run.
    Including details on total connections, disconnections and bytes downloaded.
  • The ability to edit common file types in the editor.
  • Support for recording in the Internet Explorer 11, Chrome v30 and Firefox v23 browsers.
  • The ability to create scripts from Wireshark or Fiddler files.
  • The ability to record HTML5 or SPDY protocols.


TruClient improvements
TruClient script converter. This basically replays your TruClient scripts and records the HTTP/HTML traffic allowing you to create these script typers from TruClient recordings. This is similar to recording GUI scripts and then converting to other script types.

The addition of support for Rendezvous points, IP spoofing, VTS2 and Shunra network virtualisation in TruClient scripts.

Linux Load Generator improvements
Building on the increased support for Linux Load Generators in 11.5x, LDAP, DNS, FTP, IMAP, ODBC, POP3, SMTP and Windows Sockets scripts can now be replayed through UNIX load generators.

CI/CD support
Better integration with Jenkins etc.

Platform support

  • Support for installation on Windows Server 2012.
    (LoadRunner 11.x and PC 11.x only supported up to W2K8 which was a barrier to enterprise adoption).
  • LoadRunner components can now run in a “non-admin” user account with UAC and DEP enabled.

There are numerous other improvements which are well documented in the “About LoadRunner” section in LoadRunner help. Now that the community license is available, there’s nothing stopping you from downloading it and giving it a go.

LoadRunner 11.5x replay error

I decided to give LoadRunner 11.50 a try because one of my clients is upgrading to the newer version of VuGen as part of their migration to Performance Center. I tried a simple recording and replay against the VTS2 web application (which I’m also evaluating). The script ran without problems and populated rows in VTS as I expected, but I saw this error in the replay log.

Error -27279: Internal Error – Report initialization failed, error code=-2147467259

I’m using Windows 8 and LoadRunner 11.50 build 2216. I looked in the HP support and found an article (which for some reason I can no longer find!) that suggested that the way to resolve this was to run any LoadRunner script once as an administrator. Once you’ve done this, you’ll have “cured VuGen” of this fault.

This solution worked for me, here are the steps that I took:

  • Right click the VuGen shortcut and choose the option to “run as administrator”
  • Run the script once, the error should not appear.
  • Close VuGen

I re-tested this using VuGen as a non-administrative user and can confirm that this problem no longer exists.
