Jmeter Load Testing

Fundamentals of Jmeter

Introduction

• Explain the need for load testing
• Describe various types of performance test objectives
• Identify the steps of the Jmeter methodology
• Define the term “scenario” in the context of Jmeter
• Identify strategies for creating effective scenarios

Planning an Effective Scenario

• Define measurable goals for your load test
• Gather preliminary information before load testing your system
• Organize system information effectively
• Use gathered information to plan load tests

Installation

• Describe the Jmeter architecture
• Determine where to install Jmeter components
• Identify hardware and software needed for installation

Introduction to Scenarios

• Explain the elements of a Jmeter scenario
• Present the basic steps for creating a scenario

Using Run-time Settings

• Explain the difference between Script and Scenario Run-time settings
• Configure Run-time settings based on load testing goals

Scenario Execution

• Prepare for a scenario run
• Identify techniques for running a scenario efficiently

Scheduling Scenarios

• Explain Scheduling by Scenario and by Group
• Configure Scenario Start Time
• Explain a Real-life Schedule and a Run until Complete Schedule
• Manage Schedules through the Actions grid.
• Manage Schedules through the Scenario Interactive Graph

Defining Service Level Agreements

• Define a Service Level Agreement
• Create a Service Level Agreement Goal Measured Per Time Interval
• Create a Service Level Agreement Goal Measured Over the Whole Run

Performance Monitors

• Explain the value of performance monitors
• Select performance monitors to achieve load test goals
• Add measurements for performance based goals

Analysis

• Explain the value of analyzing results
• Work with the graphs to display data

Scripting For Web

Introduction

• Define Jmeter script
• Identify the main components of the Jmeter IDE interface

Recording for the Web

• Create a script by recording user steps On the web environment
• Describe the basics of HTML and URL recording levels

Replay

• Identify and configure the appropriate web runtime setting for replay
• Replay the script in Jmeter to verify script functionality
• Recognize the debugging tools available in Jmeter

Transactions

• Insert start and end TRX in the script
• Explain what parameters are and how they work
• Solve playback problems with parameterization
• Parameterize a script for load testing

Manual Correlation

• Determine when manual correlation is required
• Correlate dynamic values using the create parameter option

Verification

• Recognize why and when to use verification
• Identify visual cues to check for during load testing
• Add Text Checkpoints during and after recording
