Jmeter AEM Templates

Introduction 

AEM JMeter template is a predefined Test Plan template, ready to use. Template accelerates performance test implementation for web applications with the JMeter tool and introduces a set of good practices.

Main features

• Parametrization - re-used, preconfigured User Variables,
• Modularization using Module Controllers,
• Tuned for Adobe AEM - a preconfigured thread that activates page on the author (to replicate page via author-publish-dispatcher path). Thread also presents how to authenticate to AEM Author instance and reuse CSRF token (works with AEM 6.5),
• Preconfigured loggers - preconfigured Simple Data Writers for .csv, .xml and Influx database (for Live monitoring).
• Other features:
• - Think times with parametrized Gaussian Random Timer,
• - Test Profiles with User Defined Variables for different test environments,
• - HTTP Request configured for download embedded resources, parallel download and filtering outcalls to 3rd parties domains,
• - Exemplary HTTP Requests (GET, POST) and Config Elements (Transaction and Throughput Controllers),
• - User agents variability - in some cases it is important to test with different user agents (CDN caching algorithms that rely on user agent, mobile channels),

Prerequisites
JMeter 5.1.1 (http://jmeter.apache.org/download_jmeter.cgi)
Plug-in Manager (https://jmeter-plugins.org/wiki/PluginsManager/)
Install plug-ins:
- 3 Basic Graphs,
- 5 Additional Graphs,
- Distribution/Percentile Graphs,

Installing template

Copy .xml snippet from "templates-snippet.xml" and paste into JMeter templates file "\bin\templates\templates.xml". Remember to preserve correct XML syntax. 

All Features

Test Plan element - with ${project} variable to be changed.

"Domains" User-Defined Variables - Server related variables for each environment. Enable or disable appropriate one (e.g.: Domains STAGING to test staging).

"Variables" User-Defined Variables - test profiles for LOAD, SOAK, STRESS tests with Thread and Time-related variables. Enable or disable the appropriate one. Data is exemplary and to be changed in a project."Main Tread" Group:
${thread} and ${rampup} variables used for Forever run.
HTTP Request Defaults element with ${domain} and ${protocol} variables used

• Embedded Resources are downloaded
• The parallel download of embedded resources = 6 (simulate browser behavior)
• Filtering out 3rd party domains - Tab Advanced ".${domain}." regular expression. No analytics will be sent.

Cookie Manager
- Clears cookie each iteration
CSV Config
- reads data from CSV file and passes to Header Manager (user-agent variable)
Header Manager
- adds Host header with ${domain} variable
Gaussian Random Timer
- adds Think Time before EVERY sample
- uses ${think-time-deviation} and ${think-time-constant} variables
Throughput Controller
- demonstrates hot to split users in percentage manner e.g.: New users vs Returning users
- Demonstrates usage of Module Controllers (reusable blocks of scripts)
- HTTP Cache manager - simulating caching assets in the browser
- HTTP request Sampler
--Response Assertion
Transaction Controller
- Demonstrates how to embed multiple samples into one Transaction.
- "Login" POST request

• Modules Thread:
• implementation of modules.
• "Activate Page EXAMPLE" Thread group
• - Activates content from ${content-demo} variable using AEM /libs/replication/treeactivation.html servlet
• - Hits Author to push the correct flow of invalidation: Author->Publish->Dispatcher
• Set of useful graphs that can be used to import .csv result files and analyze test results.
• Simple Data Writer CSV
• - Configured to write samples only to .csv file
• Simple Data Writer XML
• - Configured to write samples and sub-samples to an xml file. Use this one if you want to know Server Hits not only Transactions per second.
• Backend Listener for Live monitoring
• - Preconfigured to push summary only data to localhost Influx database.
• - uses ${project} variable to add a prefix for database measurements.
