Cloud load testing a Gatling.IO test plan on RedLine13 via Maven.

Information

Maven version 3.0.5, Java version 1.8.0_91

Gatling Version is controlled by your Maven definition.

Each agent will have its own repository, it is shared for all tests run on a single agent.

• First test on an agent will have to pull in all of your dependencies, including gatling version.
• Second test will startup faster, but running through maven is slower than just using a single simulation

Selecting version in the UI is important in terms of building percentiles and full gatling reports.

• For 2.1.x select 2.1.6
• For 2.2.x select 2.2.0

Example Test

The following was contributed by a community member asking the team to support Maven execution.

https://github.com/redline13/multi-module-gatling-for-redline13

It is a maven project for running multiple scenarios with

• One specific requirement
  • Results folder needs to be written to the base directory / output folder.  This is required for successful test run and gathering test data.
  • <resultsFolder>${project.basedir}/../output</resultsFolder>
• One suggested requirement
  • We do not collect the gatling generated report, instead we build it from scratch across all of your servers.
  • If you still generate the report per server, you can download those files as well.
  • <noReports>true</noReports>

Packaging a test

The test must be packaged so the main pom.xml is in the root when extracted.  To package the project above

# Just example of gatling-maven test
git clone https://github.com/redline13/multi-module-gatling-for-redline13
# go into the directory
cd multi-module-gatling-for-redline13
# Create a compressed tar file (file is put in the directory above)
tar --exclude .git -czf ../gatling-maven.tar.gz .

Running a test

1. Start a Test and Select Gatling
2. For Simulation drop in the .tar.gz we selected above
3. Select the gatling version
4. If you want the true gatling reports and simulation logs, check “Save the response output from individual tests and calculate percentiles”
5. Expand “Advanced Gatling test Options”
6. Check “Maven” plugin
7. Provide your maven instruction, this is everything after mvn
8. Don’t forget to select your cloud settings, # servers and locations.
9. “Start Test”!

This example is a 2 server test.

Gatling Reports (Enterprise)

The gatling output and generated report is available in “Output Files”.  This is a gatling report built from the simulation logs across all servers.

• Download “Gatling Report”
  • 
• Expand the download
  • 
• Open the index.html file and see the cross-server generated report

RedLine13 Reports

Of course RedLine13 Metrics and Reports are available across the load agents and requests.  Here is an example test run https://www.redline13.com/share/testplan/28469
