eVlite Benchmarks Updated

There are new benchmark data available for eValid's eVlite Limited Fidelity Playback feature. At the high end of capacity, our new benchmarks show that, using a fairly fast PC that is running up to 20 copies of eVlite at one time, you can simulate the activity of 20,000 user playbacks simultaneously.

Remember, eVlite activity is "non-coherent" in the sense that there is no session memory or context involved. eVlite playbacks are similar to those normally available when using a loading engine based on HTTP protocol activity. In the eValid context, eVlite work is used to create a background of high activity while measuring the performance of realistic, in the foreground, context sensitive test sessions.

URL Trace Generation Feature

The new URL Trace Creation feature is intended to make it possible to run tests, for comparison purposes, in eValid that mimic some types of less-sophisticated browser traffic generators such as those based in HTTP sequences.

In operation the new URL Trace Creation feature generates a derived script at playback time that contains the specific sequence of GetURL commands to account for every URL that the eValid browser downloaded during the script playback. The resulting derived eValid script can be used in different ways: for server load timing experiments, to create non-browser server activity, and for performance comparison purposes.

Total URL-only playback time typically exceeds that of eValid browser based playback because the browser activity is multi-threaded, whereas the sequence of GetURL commands executes serially (single thread, no parallelism).

SJSU Course on Software Test Automation Features evalid

Students in Prof. Jerry Gao's course on Software Test Automation (CMPE 296X) scheduled for the Spring 2008 will have access to eValid as part of the regular coursework.
