Synthesizing SVT Data

Overview

Preparing data for performance tests is a very important part of the preparation phase for a load test exercise. The following scripts provide simple examples of approaches to synthesize parameter data for use by the test scripts.

User Login IDs

#!/usr/bin/env python

print 'UserId'

for i in range(200):
   print "svt%03d" % i

Unquoting URL Data

#!/usr/bin/env python
