Transcript OPENSTA and ColdFusion

OPENSTA and
ColdFusion
Using Open STA for load and
functional testing ColdFusion based
applications
What is Open STA
Open Source Testing Tool
 Used to be a product called Cyrano
 Written in C++, currently windows
only
 It is actually two tools the Open Sta
commander and the Open STA
gateway.

Why Use a Testing Tool
Automate tedious jobs
 Increase code quality
 Decrease time debugging
 Increase predictability
 Create real benchmarks and metrics
for planning

Open STA VS. MS WAST
Open STA is open source
 Has richer functionality
 Less issues with SSL
 Great support and development
community

How Open STA works
Commander and Gateway
 Scripts, Collectors, and Tests

Creating a Script
Create a new script name
 Setup your browser
 Record a session

Some Comments on
Creating Scripts
Try to break down your scripts to use
cases for functional testing.
Remember you can combine many
small tests into on big test.
 Get with real stakeholders for
modeling realistic tests.

Create a Collector
Collectors are just Win NT perfmon
counters.
 You need to have CF counter on in
the admin
 Model your counters in Perfmon
 Then build a collector, collector can
have any number of counters

Create a Test
Create a new test
 Add your scripts
 Add your counters
 Adjust virtual users, monitors, ramp
up time etc.
 Tests can be changed in real time!

Analytics
Open STA Analytics are virtually
nonexistent
 You need to use some other tool but
most of the time Excel should be
sufficient.
