Cassandra can be automatically tested using various test suites, that
are either implemented based on JUnit or the
dtest scripts written in
Python. As outlined in
testing, each kind of test suite addresses a
different way to test Cassandra. Eventually, all of the tests will be
executed together on the CI platform at
Jenkins is an open source solution that can be installed on a large number of platforms. Setting up a custom Jenkins instance for Cassandra may be desirable for users who have hardware to spare, or organizations that want to run Cassandra tests for custom patches before contribution.
Please refer to the Jenkins download and documentation pages for details on how to get Jenkins running, possibly also including slave build executor instances. The rest of the document will focus on how to setup Cassandra jobs in your Jenkins environment.
In addition, the following plugins need to be installed along with the standard plugins (git, ant, ..).
You can install any missing plugins using the install manager.
Manage Jenkins → Manage Plugins → Available and install the
following plugins and respective dependencies:

Post Build Script
Source Code Management select Git using the repository:
Add build step →
Process Job DSLs and enter
Look on Filesystem:
Generated jobs will be created based on the Groovy script’s default
settings. You may want to override settings by checking
This project is parameterized and add
String Parameter for on the
variables that can be found in the top of the script. This will allow
you to setup jobs for your own repository and branches (e.g. working
When done, confirm "Save".
You should now find a new entry with the given name in your project
list. However, building the project will still fail and abort with an
error message "Processing DSL script
cassandra_job_dsl_seed.groovy ERROR: script not yet approved for use".
Manage Jenkins →
In-process Script Approval to fix this issue.
Afterwards you should be able to run the script and have it generate
numerous new jobs based on the found branches and configured templates.
Jobs are triggered by either changes in Git or are scheduled to execute
periodically, e.g. on daily basis.
Jenkins will use any available executor with the label "cassandra", once the job
is to be run.
Please make sure to make any executors available by selecting
Build Executor Status →
Configure → Add “cassandra” as label and
Executors need to have "JDK 1.8 (latest)" installed. This is done under
Manage Jenkins → Global Tool Configuration → JDK Installations….
Executors also need to have the
virtualenv package installed on their
Cassandra ships with a default CircleCI configuration to enable running tests on your branches. Go to the CircleCI website, click "Login" and log in with your github account. Then give CircleCI permission to watch your repositories.
Once you have done that, you can optionally configure CircleCI to run tests in parallel if you wish:
Projects and select your github account, and then click the settings for your project.
Set the parallelism setting. If you leave the default value of 1
for Cassandra, only
ant eclipse-warnings and
ant test will be run.
If you change the value to 4, Circle CI also runs
ant test-compression and
