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.
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.
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_hello
}
# 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"* ]]
