How to Set Up TeamCity for Load Testing

Learn how to install and configure the TeamCity CI and build server to carry out load testing as part of your continuous integration process.

Testing, in general, is an indispensable part of the continuous delivery process, and load testing should not be an exception. Let’s take a look at how to set it up in TeamCity.

TeamCity is a continuous integration and build server from JetBrains. Although it is capable of running JMeter load tests out of the box, you still must analyze the results manually. That’s not very useful as the concept of CI is based on automation. That’s where the SmartMeter.io tool comes in. Let's dive in.

1: Installation

You need to download and install SmartMeter.io to be able to run the load tests (here’s an installation guide in case you need any help).

Let’s assume you have TeamCity already functional and your TeamCity user has proper permissions to run the SmartMeter.io installation.

2: Basic Information

Before we begin, you have to gather some information about your SmartMeter installation:

  • SmartMeter.io installation directory - TeamCity’s agent need to have access to this directory and to run SmartMeter.sh in it. Example: /usr/local/bin/smartmeter/

  • Test directory - directory, that contains prepared .jmx scripts. This is usually pulled from Version Controll System (VCS). Example: /home/teamcity/tests

  • Reports directory - directory to store reports from SmartMeter.io. These reports will be artifacts for your build runs. Example: /home/teamcity/reports in our setup.

3: Running SmartMeter.io Tests From TeamCity

3.1: Configuring Build Parameters

1) Add new parameters to your build configuration. Go to Parameters section of your build configuration. Click the button Add new parameter.

2) Add ReportIndex to parameters. Create parameter with this configuration:

  • Name - ReportIndex

  • Kind - Configuration parameter

  • Value - index.html

  • Spec - text validationMode='not_empty' label='Perf Report' display='normal'

Image title

3) Add TrendsIndex to parameters. Almost the same as in the previous step:

  • Name - TrendsIndex

  • Kind - Configuration parameter

  • Value - trends.html

  • Spec - text validationMode='not_empty' label='Trends' display='normal'

4) Add ReportUrl to parameters. This will be the URL where you find report of the build. We will use predefined build parameters: teamcity.serverUrl, system.teamcity.buildType.id, build.number

  • Name - Reporturl

  • Kind - Configuration parameter

  • Value - http://%teamcity.serverUrl%/repository/download/%system.teamcity.buildType.id%/%build.number%/

  • Spec - text validationMode='not_empty' label='Report Url' display='normal'

5) Now we have these three parameters configured.

3.2: Configuring Artifacts

1) Go back to General settings of the Build configuration settings of your project.

Image title

2) Add parameters to Artifacts paths.

%ReportIndex%
%Reporturl%
%TrendsIndex%
/home/teamcity/reports/report-%build.number%

Image title

3.3: Configuring Build Steps

1) Go to the build configuration of your project and add a new build step. Set up:

  • Runner type: Command Line

  • Step name: Run Smartmeter test (or whatever you like)

  • Run: Executable with parameters

  • Command executable: path to SmartMeter /usr/local/bin/smartmeter/SmartMeter.sh

Command parameters: runTestNonGui <path/to/tests/dir>/test.jmx -Jetn_report_name=%build.counter% -Jetn_reports_path=<path/to/reports/dir>
where <path/to/tests/dir> is a directory where you store or download your test scripts and <path/to/reports/dir> is a directory where you want to store reports

2) Next we want to create report page. Add a second build step with this config:

Runner type: Command Line
Step name: Create report page (or whatever you like)
Run: Custom script

Custom script:

echo '<script>location="%Reporturl%%ReportIndex%"</script>' > %ReportIndex%

Image title

3) And a final build step is for creating trends page.

  • Runner type: Command Line

  • Step name: Create trends page (or whatever you like)

  • Run: Custom script

Custom script:

echo '<script>location="%Reporturl%%TrendsIndex%"</script>' > %TrendsIndex%

3.4: Configuring Report Tabs

We have set up parameters and configured build steps. Now we want to set up reports to appear right in the build view or project view.

1) Go to your TeamCity project settings.

Image title

2) Open Report tabs section. You will see Create new project report tab button and Create new build report tab button.

Image title

3) By using these buttons we will add reports to our project or build view. Let’s start with build report. Click on Create new build report tab button. Configuring it is very easy. Just type the name of the tab to Tab Title, e.g. “Perf test report.” Leave Start page unchanged - it should contain value “index.html.”

Image title

4) Now click Create new project report tab button and set these values:

  • Tab Title: Perf trends

  • Get artifacts from: choose the name of your project’s build configuration. In the second combobox, choose Last successful build.

  • Start page: trends.html

Image title

5) You should see the tabs in the configuration.

3.5: First Trial Run

If everything is configured, you can try the first run of a test.

1) Go to your project home and click the Run button.

2) After a few moments, the SmartMeter test will start. You can see the progress in the build log.

Image title

3) After finishing the test, SmartMeter will generate a report and TeamCity will add it to the Report Tabs. You can see a result analysis in the Build detail.

Image title

4) Trends analysis can be seen in Project home view in tab Perf trends. Run your test multiple times, and you will see how tables and charts will change.

4: Next Steps

You should now be able to run a load test in TeamCity with SmartMeter.io. If you’re not familiar with the tool and want to learn more about test creation and other features, visit the learn section. You can also follow tutorials for Jenkins and Bamboo.
