+to create code coverage information:
 
 ```bash

 npm run test:cover
 ```
 
-This will start a watcher for changes of the code.
+### Integration Tests
 
-`ganache-cli` can be installed following [this instructions](https://github.com/trufflesuite/ganache-cli#installation).
+Besides a running `ganache-cli` instance, a locally running Ocean network is required. To do so before running the tests, use [Barge](https://github.com/oceanprotocol/barge):
 
-### Production build
+```bash
+git clone https://github.com/oceanprotocol/barge
+cd barge
+
+./start_ocean.sh --latest --no-pleuston --local-spree-node
+```
+
+In another terminal window, run this script and export the seed phrase:
+
+```bash
+# copies the contract artifacts once the local Ocean network is up and running
+./scripts/wait_for_migration_and_extract_keeper_artifacts.sh
+
+# export Spree accounts seed phrase
+export SEED_WORDS="taxi music thumb unique chat sand crew more leg another off lamp"
+```
+
+Once everything is up, run the integration tests:
+
+```bash
+npm run integration
+```
+
+to generate code coverage information during test, run:
+
+```bash
+npm run integration:cover
+```
