Step-by-Step Preparation Guide
Step 1: Download and Install IBM Rational Performance Tester
Start by getting familiar with the tool itself. IBM offers a trial version you can use for learning purposes. Install it on your system and spend at least a week getting comfortable with the interface. Click through different menus, create simple test projects, and record basic scripts.
Step 2: Master the Fundamentals
Focus on these core areas:
Script Creation and Recording
Learn how to record user actions and convert them into test scripts. Practice recording different types of applications web apps, mobile apps, and client-server applications. Each type has unique considerations.
Data Correlation
This is where many people struggle. Data correlation means identifying dynamic values in your scripts and replacing them with variables. Spend extra time practicing this skill, as exam questions heavily focus on correlation scenarios.
Load Scheduling
Understand how to create realistic load patterns. Learn the difference between constant load, increasing load, and spike testing. Practice creating schedules that mirror real user behavior.
