Generating Dynamic UUID with a Javascript Data Source
We recently had a customer question on how to dynamically generate UUIDs during a load test, and the answer illustrates two interesting techniques in Load Tester:
How to use javascript to dynamically generate data during a test.
How to make call outs to the more extensive Java functions within javascript.
In this example let’s assume the UUID is being used as a path element that you want to dynamically replace during a test like this:
http://mysite/path1/123e4567-e89b-12d3-a456-426614174000
Like much of the test case configuration in Load Tester, the process to edit the dynamic behavior starts in the Fields View. Click on the URL to select … Continue reading »
New JavaScript optimizer
From a load testing perspective, we are not generally concerned with Javascript performance – since it affects client-side rendering time and therefore has little relationship to load. However, we do see a lot of sites that could benefit greatly from improved Javascript performance – especially reducing the size of their Javascript files. Google has a relatively new project, Closure Compiler, that optimizes JavaScript code to reduce size and improve performance.
If you’ve tried the Closure Compiler, give us a shout. We’d love to hear about your results!
