AUTHENTICATION:
Go to the Stb-tester Portal in your web browser and create an
access token. See
https://stb-tester.com/manual/rest-api-v2#authentication
When you run this script the first time, you will be prompted to
type in the access token. If you have the Python "keyring"
package installed, we will save the token in the secure password
storage provided by your operating system, so that you don't have
to type it in again.
You can also save the access token to a file (don't commit the
file to the git repository!) and give the filename with
--portal-auth-file.
In Jenkins you can use the Credentials Binding plugin to pass the
access token in an environment variable. See the Jenkins
documentation below.
INTERACTIVE MODE:
In interactive mode (the default mode if not running inside a
Jenkins job) the "run" command takes a snapshot of your current
directory and pushes it to the branch "YOUR_USERNAME/snapshot" on
GitHub, so that you don't have to make lots of temporary git
commits to debug your test scripts.
JENKINS INTEGRATION:
We automatically detect if we are running inside a Jenkins job.
If so, we enable the following behaviours:
* Read the access token from $STBT_AUTH_TOKEN environment
variable.
* Record various Jenkins parameters as "tags" in the Stb-tester
results:
- jenkins/BUILD_ID
- jenkins/BUILD_URL
- jenkins/GIT_COMMIT
- jenkins/JOB_NAME
- jenkins/SVN_REVISION
* Write test results in JUnit format to "stbt-results.xml" for
the Jenkins JUnit plugin.
* Stop the tests if you press the "stop" button in Jenkins.
For instructions on how to configure your Jenkins job see
https://stb-tester.com/manual/continuous-integration
BAMBOO INTEGRATION:
Similarly, we automatically detect if we are running from
Bamboo (Atlassian's continuous integration server):
* Read the access token from bamboo.STBT_AUTH_PASSWORD variable.
* Record the following Bamboo variables as "tags" in the
Stb-tester results:
- bamboo.buildPlanName
- bamboo.buildResultKey
- bamboo.buildResultsUrl
- bamboo.planRepository.branchName
- bamboo.planRepository.revision
* Write test results in JUnit format to "stbt-results.xml"
