+## Continuous System and Integration Testing (CSIT) for CPS
+
+The directory structure:
+
+- **plans/** contains testing plans, each sub-folder represents a separate test plan, contains processed subsequently:
+    _startup.sh_ (serves docker containers startup), _testplan.txt_ (lists test-suits), _teardown.sh_ (serves docker containers stopping and images removal)
+- **scripts/** contains shell scripts used on tests executions
+- **tests/** contains test suits which are processed by folder name (relative to _tests_ folder) taken from _testplan.txt_
+
+Test suits are executed using Robots framework.
+
+### Running on local environment
+
+Prerequisites: 
+- docker
+- python + pip
+
+```bash
+sudo apt install python3-pip 
+```
+
+The Robot framework and required python packages will be installed on first execution.
+
+Build a docker image (see also [docker-compose readme](../docker-compose/README.md) ):
+
+```bash
+mvn clean package -Dmaven.test.skip=true -Dnexus.repository= -Pcps-xnf-docker
+```
+
+Execute test from current folder:
+```bash
+./run-project-csit.sh
+```
+
