Introduction

• Load testing tools can be used to test the system
  behavior and performance under stressful
  conditions by emulating thousands of virtual
  users.
• eValid can run a Load Test scenario made up of
  repeated playbacks of multiple script files at
  varying delay multiplier values.
• By running multiple copies of the eValid browser
  simultaneously, eValid can impose heavy work
  loads on a Web Server.

Load Test capability of eValid

• Two scripts, .evs which is the reference script
  used by master script for load test which will be
  .evl
• The master script (see example below) runs each
  specified script in a separate eValid sub-browser
• Each script runs without cache (make such setting
  through cache manager) to assure that each page
  is actually downloaded, not just read from local
  storage

Load Test capability of eValid

• The load test scenario expressed in the
  master script can be made up of a set of
  pre-recorded script files and with
• Any delay multiplier value, e.g. 0.9 or 1.25 or??
  
• Any repetition count value, e.g. 1 or 5 or 100
  or??
• Each eValid sub-browser runs the script the
  specified
• number of times at the specified delay
  multiplier, and then
• closes itself.
• Timing data on each complete playback is written
  to
• single consolidated timing log file, the default
  name of
• which is LoadTest.log.

Steps to create the Load Test Scripts

• 1. Create a test script, .evs file, to
  include one URL for the session loads.
• 2. Next, select File gt New Load Test to begin
  constructing a separate master LoadTest script.
• 3. Use the LoadTest Script Generator to
  create a LoadTest Script.
• 4. Select Settings gt Record/Play Preferences
  and click Display HTML Load Test Monitor. Make
  sure that only this option is clicked. This
  enables the Real-Time monitoring function.
• 5. Select Playback gt Start Playback to
• begin the LoadTest.
