+# 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](https://github.com/sstephenson/bats) 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 TESTFLAGS="/checkpoint.bats"
+```
+
+
+To run them on your host, you will need to setup a development environment plus
+[bats](https://github.com/sstephenson/bats#installing-bats-from-source) 
+For example:
+```
+$ cd ~/go/src/github.com 
+$ git clone https://github.com/sstephenson/bats.git 
+$ cd bats 
+$ ./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]
+(https://github.com/opencontainers/runc/blob/master/test/integration/helpers.bash)
+are provided in order to facilitate writing tests.
+
+```sh
+#!/usr/bin/env bats
+
+# This will load the helpers.
+load helpers
+
+# setup is called at the beginning of every test.
+function setup() {
+  # see functions teardown_hello and setup_hello in helpers.bash, used to
+  # create a pristine environment for running your tests
+  teardown_hello
+  setup_hello
+}
+
+# teardown is called at the end of every test.
+function teardown() {
+  teardown_hello
+}
+
+@test "this is a simple test" {
+  run "$RUNC" start containerid
+  # "run" automatically populates $status, $output and $lines.
+  # Please refer to bats documentation to find out more.
+  [ "$status" -eq 0 ]
+
+  # check expected output
+  [[ "${output}" == *"Hello"* ]]
