Environment Variables

The Jenkins Plugin passes your build step information to your Selenium scripts as environment variables. The exact syntax will vary depending on your scripting language.

Variable Description
CBT_USERNAME the username used on for Selenium Testing
CBT_AUTHKEY the apikey used on for Selenium Testing
CBT_BUILD_NAME the Jenkins Project's name
CBT_BUILD_NUMBER the Jenkins Project's current build number
CBT_OPERATING_SYSTEM the apiname of the selected Operating System
CBT_BROWSER the apiname of the selected Browser
CBT_RESOLUTION the name of the selected Screen Resolution
CBT_BROWSERNAME the browser name without the version (only needed for Javascript Selenium Tests)
CBT_BROWSERS an array of JSON objects containing the "operating_system", "browser", "resolution, and "browserName" of each configuration specified

See the examples directory for a few language specific sample scripts.

Saving Your API Credentials
  1. Go to your installation's management screen.
  2. Click Configure System.
  3. Find the section labeled
  4. Click Add
  5. Select Jenkins as the "Jenkins Credentials Provider"
  6. Select as the "Kind"
  7. Enter your Username and API Key information. You can find your api key here (must be logged in)
  8. Test the credentials using the Test Credentials button
  9. Click Add.
  10. Select the credentials on the "configuration page"
  11. Optional: You can also create and select credentials for each build within the build configuration page.
Enable Selenium and Screenshot Views
  1. In the Build Environment, Select "Enable Test Results Pages"
  2. During your build, links on your sidebar will populate and allow you to interact with the test.
  3. You can view and download screenshots for a Screenshots Test
  4. You can view videos, snapshots, and network packet captures for Selenium Tests


Build Environment
  1. Configure your Jenkins Project.
  2. In Build Environment, Check the box next to
  3. For Screenshot Tests: Pick a BrowserList and enter a URL (you must have you API credentials saved for the browserlist to populate). You can add multiple Screenshots Tests by clicking "Add a Screenshots Test"
  4. For Selenium Tests: Add the Operating System, Browser, and Screen Resolution that you want to run a Selenium Test on. You can add multiple configurations by clicking "Add a Selenium Tests"
  5. Optional: Check Use Local Tunnel to run tests on webpages behind your firewall. The CBT NodeJS Tunnel is embedded into the plugin and does not need to be install on the Jenkins Server. 
    1. To use a named tunnel, enter the "Tunnel Name" in the advanced section.
    2. If you prefer not to use the embedded local tunnel and want to use the local tunnel installed on your system, you can specify the path to the local tunnel binary in the advanced section.
  6. For CBT Credentials: Select the credentials to run the tests with.
Execute a Selenium Test
  1. Execute a Selenium Test just as normally would with Jenkins.
  2. For example, if you were running a script written in python on a Unix machine, within the Build section, select Add Build Step and Execute Shell (if you have the Python Plugin installed you can use it instead).
  3. Enter the command to run your script ie. "python"
  4. Click Save
  5. Click Build Now to build the project. Output from the tests will be displayed in Console Output for the build.
Pipeline Configuration

As of version 2.3, the plugin supports Jenkins Pipeline. Here's an example of a pipeline script:

pipeline example

cbt(credentialsId: 'your_credential_id', useLocalTunnel: true, useTestResults: true) {
    cbtScreenshotsTest browserList: 'Your BrowserList', url: ''
    cbtSeleniumTest(browser: 'Safari10', operatingSystem: 'Mac10.12', resolution: '1024x768') {
        sh 'python'
