1. In case runc binary file name is not runc, the test fails like
below. The fix is to get the binary name from $RUNC.
✗ runc command -h
(in test file tests/integration/help.bats, line 27)
`[[ ${lines[1]} =~ runc\ checkpoint+ ]]' failed
runc-go1.25.0-main checkpoint -h (status=0):
NAME:
runc-go1.25.0-main checkpoint - checkpoint a running container
2. Simplify the test by adding a loop for all commands. While at it, add
a loop for -h --help as well.
3. Add missing commands (create, ps, features).

runc Integration Tests
Integration tests provide end-to-end testing of runc.
Note that integration tests do not replace unit tests.
As a rule of thumb, code should be tested thoroughly with unit tests. Integration tests on the other hand are meant to test a specific feature end to end.
Integration tests are written in bash using the bats (Bash Automated Testing System) framework.
Running integration tests
The easiest way to run integration tests is with Docker:
make integration
Alternatively, you can run integration tests directly on your host through make:
sudo make localintegration
Or you can just run them directly using bats
sudo bats tests/integration
To run a single test bucket:
make integration TESTPATH="/checkpoint.bats"
To run them on your host, you need to set up a development environment plus bats (Bash Automated Testing System).
For example:
cd ~/go/src/github.com
git clone https://github.com/bats-core/bats-core.git
cd bats-core
./install.sh /usr/local
Note
: There are known issues running the integration tests using devicemapper as a storage driver, make sure that your docker daemon is using aufs if you want to successfully run the integration tests.
Writing integration tests
helper functions are provided in order to facilitate writing tests.
#!/usr/bin/env bats
# This will load the helpers.
load helpers
# setup is called at the beginning of every test.
function setup() {
setup_busybox
}
# teardown is called at the end of every test.
function teardown() {
teardown_bundle
}
@test "this is a simple test" {
runc run containerid
# "The runc macro" automatically populates $status, $output and $lines.
# Please refer to bats documentation to find out more.
[ "$status" -eq 0 ]
# check expected output
[[ "${output}" == *"Hello"* ]]
}
