No this is not a post on how to get free licenses… There should be no doubt that purchasing LoadRunner licenses is expensive. How Mercury/HP has achieved this stranglehold on the market is strange to behold but it is the way it is. Needless to say, in another purchasing license cycle I jokingly said to a colleague [...] Alas, it can’t be done in JMeter. So this is how it works in LoadRunner … The wheel has turned full circle and I’m back in MQ land… So here is a a simple Java vuser harness which you can use in LoadRunner to put or get messages from Websphere MQ. This version doesn’t require any JNDI bindings (or access to JMS). Instead it just uses a standard server connection channel [...] This is a relatively new example of how to use JMeter with WebSphere MQ. This approach is a clever way of inserting messages into MQ using a JMS sampler (point to point) with a JNDI binding within MQ. I had not heard of this approach before and am sure it will be useful in future, provided [...] Often when performance testing in a black box environment, you are left with the onerous responsibility to report against response time performance. A typical approach by performance testers is to rely on 95th percentiles, which is effectively a Service Level Agreement (SLA) saying that 95 percent of all my samples have a response time below 5 [...] When/if I am asked to conduct interviews again for potential performance test analysts, I think I will include this question in my repertoire to suss out those in the know, and those just, um, pretending … Here is a great analogy of throughput and latency. I don’t pretend to understand queuing theory (just yet), but am [...] A new version of FireWatir has been released. This includes some fixes related to Firefox 3 but more importantly, it marks the merger of FireWatir and Watir projects, allowing for tighter coupling of methods and functionality between the two, allowing you to write less code =) To use FireWatir, you will have to install a Firefox [...] In an effort to get more actively involved with the open source community, I’ve recently starting working with another colleague on a new site called justaddwatir.com. This is an exciting collaboration of examples for web application testing in ruby (watir – pronounced “water”). Watir is a simple open-source library for automating web browsers. It allows you [...] This is most likely because the JMeter recording proxy does not support the https protocol. If it’s a screen you can live without, you can just stop/start the proxy recorder around that page (I use the Firefox plugin called FoxyProxy to quickly switch between different proxy configurations). However, if it is vital to your script (for [...] Just a quick post for myself so I don’t forget… I needed to generate a random alpha for use in a LoadRunner web vuser script. The native LoadRunner parameters can do random numerics and date/times but I couldn’t find a way to generate only characters, as one might need to generate a random password for [...] |
