Are the tools that you are using to test your application affecting the results of those tests?

Success_failure.jpgVirtualization is all around us, and you may be considering using virtual servers as a load generator. There is support for this option in LoadRunner and Performance, but the question to ask is “Are the tools that you are using to test your application affecting the results of those tests?”

Recording HTTP traffic on iOS devices with HP LoadRunner

recording HTTP 2.pngiOS devices such as iPhones and iPads have become a valuable part of the IT infrastructure. As a result, there is a need to validate the performance of these devices as they run applications. HP LoadRunner, as the leading performance testing tool in the market, is the perfect choice for this validation. To get started, LoadRunner needs to obtain the HTTP activity performed by the device. Because LoadRunner’s network traffic recording mechanism doesn’t run on iOS, we have a way of getting at the HTTP activity.

 

Continue reading to find out how LoadRunner can be used to access and record HTTP traffic on the iOS device.

The Protocol Complexity Matrix and what it means for your load testing

protocol complexity matrix.PNGThere are a few general rules that apply to protocols and load testing. One is that if you want to make the job of scripting easier, it comes at the cost of memory.

This is because using more memory makes the protocol less scalable up to the point.

 

Keep reading to find out how you can easily understand the relationship between memory and how many users your load generator can run.

Working with HP LoadRunner and HP Network Virtualization

02.pngHP Network Virtualization (NV) helps you test the point-to-point performance of network-deployed products under real-world conditions. You can simulate network effects such as latency, packet loss and bandwidth, allowing your test to run in an environment that closely resembles the actual deployment of your application.

This becomes even more important in the mobile world, where performance testers must take into consideration the different communication conditions which are affected by the network operators, infrastructures, etc.

 

Continue reading to learn about how NV integrates with HP LoadRunner to provide the complete testing experience for all network situations.

Is testing at its essence just “faking it”?

design learn simulate.pngFor my first true testing job, I was totally over my head. I was young, inexperienced and honestly had no clue what I was doing. Yet somehow I was able to convince everyone that I knew what I was doing as a testing expert.

 

I learned how to be an “expert” by watching those who truly were and mimicking what they did. The same is true of application testing today. In load testing, we apply a load to fake a real system into believing real people are accessing it so we can understand how the system under test (SUT) will respond in the real world.  Keep reading to find out how you can better take advantage of this principle in your environment.

Virtual services in load testing with the HP LoadRunner and HP Service Virtualization integration

Imagine you’re a performance engineer who has to test a composite application which relies on a number of business services, some of which are developed in-house, and some of which are third-party services. You find out that one of the in-house services doesn’t work, and you also discover that you’re not allowed to perform load testing on one of the third-party services because it’s a production service. How can you go ahead with your performance testing, when there are key services that you can’t access?

 

Continue reading to find out how HP Service Virtualization is integrated with HP LoadRunner to create virtual services that let you carry on working even when services aren’t available.

Testing asynchronous business processes with LoadRunner

In the early days of the World Wide Web, web applications communicated using conversations that had a synchronous nature: the user interacts with an application that is presented in a web browser, the browser submits a request to the web server, the server sends a response, and the application in the browser is updated.

 

However, synchronous applications have a number of limitations. One limitation involves the inability of the client to reflect events occurring at the server. This could be critical if, for example, the application in question displays stock prices or sport results and must present the updated info at all times. The answer to these limitations is asynchronous communication, whereby responses from the server arrive periodically or as a reaction to server-side events.

 

Many of today’s applications combine synchronous (user-initiated) and asynchronous (application-initiated) modes of communication between the client and the server. Usually the two occur in parallel (e.g. a user is navigating within the bank’s site, while at the same time stock updates keep pouring in), which makes it hard to accurately emulate such applications using traditional Vuser scripts. 

 

Continue reading to learn how to use VuGen to create a script for asynchronous situations.
