Osmocom Titan TTCN3 Testsuites¶
In 2017, Osmocom started to create extensive tests suites for the Cellular Network Infrastructure elements. Those suites are written in the TTCN-3 programming language and use the compiler + executor of the Eclipse_TITAN project.
Source Code / Patches¶
The source code of our test suites lives in theosmo-ttcn3-hacks
repository
- cgit web interface: http://git.osmocom.org/osmo-ttcn3-hacks/
- clone:
git clone git://git.osmocom.org/osmo-ttcn3-hacks
- patch review: https://gerrit.osmocom.org/#/q/project:osmo-ttcn3-hacks
We're following the Gerrit process for patch review.
Test Suites¶
Running a testsuite¶
You have multiple options on how to execute a test suite.
Running test suite in the dockerized environment¶
This is the much easier way to run the test suite. No manual configuration of Osmocom programs or the test suite are required. Both the Osmocom program (Implementation Under Test) as well as the test suite are packaged as docker containers, which are then executed next to each other using a docker network with the "right" addresses between IUT and testsuite.
Also, using this setup you will be guaranteed to run in the exact same environment as the automatically-executed tests on jenkins.osmocom.org, i.e. your results should be exactly identical, without any differences introduced by your runtime environment, whether specific library versions or intentional or inadvertent configuration differences.
Installing docker¶
Make sure you have *docker-ce* installed (not to be confused with the possibly outdated version that may be shipped in your distribution's repositories). Check that the version string contains -ce
as follows:
$ docker -v Docker version 18.06.1-ce, build e68fc7a
Next, add yourself to the docker
group, log off and on again, and verify that you can use docker from your user:
$ docker info
Cloning docker-playground¶
First install docker on your system and add yourself to the docker group. Then clone and build the containers from the docker-playground
git repository:
$ git clone git://git.osmocom.org/docker-playground $ cd docker-playground
In theory you could run make
now to build all containers. However, not all of them are maintained, so this will most likely fail. Instead take a look at the Jenkins script of a specific project to figure out its dependencies and then build these containers.
Running a testsuite¶
Let's assume you'd want to run the testsuite for OsmoBSC. You would need to- look at its jenkins.sh to understand which containers are required.
- build those respective containers - at time of writing, this would be:
$ make osmo-stp-master osmo-bsc-master osmo-bts-master ttcn3-bsc-test
- run the
jenkins.sh
script of thettcn3-bsc-test
suite:$ cd ttcn3-bsc-test && ./jenkins.sh
jenkins.sh
script will make sure to
- create the needed docker network[s]
- run all the required containers (IUT, helpers, testsuite)
- shut them down after test suite execution
- collect the log files after execution,
/tmp/logs
will contain them
Tagging images¶
If the build fails with a message like the following:
repository docker.io/laforge/debian-jessie-build not found: does not exist or no pull access
Then apply this patch and try again (sent to review, will likely be merged soon).
Running only a sub-set of the test cases¶

Running it native on your machine¶
This is the most complicated bit to set-up, as you will have to run the respective Osmocom Program (Implementation Under Test) in the right configuration with all the IP addresses, port numbers, config file, etc. exactly like it's expected by the test suite.
You will need a deeper understanding about how the test suite works, and what its requirement are.
