+# Integration tests for sysrepo-snabb-plugin
+
+# Requirements
+* Sysrepo 
+* Snabb
+* Libyang
+* Python packages inside of "requirements.txt"
+* Robot framework
+
+# Running
+Before running the tests for the first time run the as ```setup.sh``` script
+as root, also make sure that you have built the the plugin and have snabb installed.
+The script will fetch the configuration file for the tests and 
+create the virtual interfaces needed for execution of the tests.
+It will also create a python virtual environment with the needed 
+python packages.
+
+Activate virtual python environment with
+```
+source ./test-venv/bin/activate
+```
+
+After you have done all that, you may run the tests with
+```
+robot ./src/Main.robot
+```
