rkt functional tests
This directory contains a set of functional tests for rkt.
The tests use gexpect to spawn various
rkt run commands and look for expected output.
Semaphore Continuous Integration System
The tests run on the Semaphore CI system through the
rktbot user, which is part of the
coreos org on Semaphore.
This user is authorized against the corresponding
rktbot GitHub account.
The credentials for
rktbot are currently managed by CoreOS.
The tests are executed on Semaphore at each Pull Request (PR). Each GitHub PR page should have a link to the test results on Semaphore.
Developers can disable the tests by adding
[skip ci] in the last commit message of the PR.
Select the "Other" language. We don't use "Go" language setting, because rkt is not a typical go project (building it with a go get won't get you too far). Also, the "Go" setting is creating a proper GOPATH directory structure with some symlinks on top, which rkt does not need at all and some go tools we use do not like the symlinks in GOPATH at all.
The tests will run on two VMs. The "Setup" and "Post thread" sections will be executed on both VMs. The "Thread 1" and "Thread 2" will be executed in parallel in separate VMs.

Other possible commands
The LKVM stage1 or other versions of systemd are not currently tested. It would be possible to add more tests with the following commands:
./tests/build-and-run-tests.sh -f src -s v227 -c ./tests/build-and-run-tests.sh -f src -s master -c ./tests/build-and-run-tests.sh -f src -s v229 -c
build-and-run-tests.sh parameters description
The build script has the following parameters:
-c- Run cleanup. Cleanup has two phases: after build and after tests. In the after build phase, this script removes artifacts from external dependencies (like kernel sources in the
kvmflavor). In the after tests phase, it removes
rktbuild artifacts and (if the build is running on CI or if the
-xflag is used) it unmounts the remaining
rktmountpoints, removes unused
rktNICs and flushes the current state of IPAM IP reservation.
-d- Run build based on current state of local rkt repository instead of commited changes.
-f- Select flavor for rkt. You can choose only one from the following list: "
-j- Build without running unit and functional tests. Artifacts are available after build.
-s- Systemd version. You can choose
masteror a tag from the systemd GitHub repository.
-u- Show usage message and exit.
-x- Force after-test cleanup on a non-CI system. WARNING: This flag can affect your system. Use with caution.
Ubuntu 14.04 LTS v1503 (beta with Docker support).
The platform with Docker support means the tests will run in a VM.
Manually running the tests
The tests can be run manually. There is a rule to run unit, functional and all tests.
The unit tests can be run with
make unit-check after you built the project.
The functional tests require to pass
--enable-functional-tests to the configure script, then, after building the project, you can run the tests.
./autogen.sh ./configure --enable-functional-tests make -j4 make functional-check
For more details about the
--enable-functional-tests parameter, see configure script parameters documentation.
To run all tests, see functional tests to configure and build it with functional tests enabled. Instead of
make functional-check you have to call
make check to run all tests.
Passing additional parameters
You can use a
GO_TEST_FUNC_ARGS variable to pass additional parameters to
This is mostly useful for running only the selected functional tests.
The variable is ignored in unit tests.
make check GO_TEST_FUNC_ARGS='-run NameOfTheTest' make functional-check GO_TEST_FUNC_ARGS='-run NameOfTheTest'
go help testflag to get more informations about possible flags accepted by
Running the benchmark
Running the benchmark is similar to running the other tests, we just need to pass additional
make check GO_TEST_FUNC_ARGS='-bench=. -run=Benchmark' make functional-check GO_TEST_FUNC_ARGS='-bench=. -run=Benchmark'
