A common requirement when load testing is to populate subsequent requests with dynamic data from previous requests. If you’re thinking about using a database to store static test data, such as usernames, paswords, credit card numbers etc then read on to find out how to extract this data at runtime and populate JMeter variables. So I’ve been working on a system where the MySQL instance on EC2 sporadically locks up (mysqld is zombied) during a snapshot process =) Essentially the EC2 snapshot is triggered like this: system("xfs_freeze -f /vol") and die; This method is based on advice from here Notice I [...] Well the subject goes without saying. I’ve been working on WinXP again lately and when I’m not around my favourite text editor on the mac (TextMate) I opt for SCiTE on windows. The following settings I find useful for this simple but powerful text editor. YMMV. In my last post I made a tongue-in-cheek observation that load testing really doesn’t work by today’s perceived standards for web automation and testing. Part of my grievance for that was based on frustration in dealing with different load testing platforms.

Load testing does not work for web as it is today primarily because… I really like the concept of Getting Things Done. I’m also a fan of Inbox Zero. Well, at least try to be. Here’s how I implement GTD using my gmail account… Here’s an idea… Ever been in a LoadRunner contract where you’ve got a ton of scripts to write for business transactions that have many many design steps? Even worse, have you had to write those scripts against a development environment with an unstable code base and shocking performance? Sound familiar? Ever felt the frustration of re-recording [...] In mathematics, Fibonacci numbers are the following sequence of numbers: By definition, the first two Fibonacci numbers are 0 and 1, and each remaining number is the sum of the previous two. This naturally occurring sequence is useful for determining the amount of time to sleep whenever you [...] Version control is not something you often associate with performance testing scripts. The reasons generally vary. A significant one is the lack of any version control support in commercial toolsets like LoadRunner. Another reason is the perceived short-term shelf life of test scripts. You tend to write them once and throw them away right? If you [...] |
