 ## Running the tests
 
-### Local testing
-
 To run the tests it is recommended that you use an in-memory instance of the eventstore so you don't pollute your dev instance.
 
-    EventStore.ClusterNode.exe --run-projections=all --memdb –certificate-file=yourcert.pfx
+    EventStore.ClusterNode.exe --memdb
-    or
-    ./run-node.sh --run-projections=all --memdb –certificate-file=yourcert.p12
-
-You can also use docker-compose :
-
-```bash
-# start the single node cluster
-npm run compose:single:start
-# if you want to wait for the cluster to be available
-npm run compose:wait
-# run the tests
-npm run test
-# to cleanup (stop containres, delete volumes)
-npm run compose:single:stop
-```

-For SSL setup see:
-
-https://eventstore.org/docs/server/setting_up_ssl/  
-or  
-https://eventstore.org/docs/server/setting_up_ssl_linux/
 
 To execute the tests suites simply run
 
     npm test
 
-### Isolated environment
