How to set up a simple Jenkins project to automatically run a load test in Flood.
Jenkins is a highly regarded open-source automation tool that facilitates some integral technical capabilities used in the continuous delivery process. Its primary usage pattern is to execute functional test automation and performance test suites to validate against software builds.
Using Jenkins with Flood to schedule performance tests utilises our very powerful Flood API. When a Jenkins build has completed you can automatically trigger a load test via the following simple process.
Create a new Freestyle project and click OK.
You will be directed to a General settings area. Enter a short meaningful description of this project - such as the following:
Select the option This project is parameterized and add a File parameter as follows:
Add as many file parameters as your load test requires. You will need at least one for your test script. If you are using CSV data files - then a file parameter is needed for each file.
The test script name such as Script.jmx denotes it as a JMeter script file. If you want to use Flood Element use the .ts extensions, .java extension for Selenium and .scala extension for Gatling.
Once we have added the file parameters - we need to setup a Build command that will run our script automatically on Flood.
From the Build Triggers tab, go to the Build section and add a new Build step.
Select the option Execute shell and paste the following curl command:
curl -u <YOUR_API_KEY>: -X POST
-F "flood[tool]=jmeter" \
-F "flood[threads]=10" \
-F "flood[rampup]=60" \
-F "flood[duration]=300" \
-F "flood[privacy]=public" \
-F "flood[name]=Jenkins Test" \
-F "flood[grids][infrastructure]=demand" \
-F "flood[grids][instance_quantity]=1" \
-F "flood[grids][region]=us-west-2" \
-F "flood[grids][instance_type]=m5.xlarge" \
*Please ensure you use your own API token and replace the <YOUR_API_KEY> with your generated token. To get your API token, go to your Flood account and then click on the API Access menu.
Click on reveal token link to get the token value.
Finally, click Apply and then Save the project.
You can click on the Build with Parameters menu item within your newly created project as follows:
Once clicked, simply select the correct files from your local computer and click Build.
Once the test is running, monitor it from your Console Output and Flood Dashboard to ensure that the test has been launched.
The console output should look similar to the following:
Of particular note, is the Finished: SUCCESS message being returned as part of the response. Also, a URL link to the live running test dashboard is given as the permalink value.
Using your Flood API token on a Jenkins environment allows potential third party services or other users to launch any kind of load test using your account. If you think your API token or Flood Account has been compromised you should delete and re-generate the corresponding token from your account to prevent further unwanted use.
Combining Jenkins and a load test tool gives you the ability of potentially tracking your application’s performance over time. It allows you to pinpoint what build introduced a performance regression or even a performance benefit.
