## 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
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/
EventStore.ClusterNode.exe --memdb
To execute the tests suites simply run
npm test
### Isolated environment
To be able to run the tests for different connection types (tcp, gossip, cluster) docker-compose files are available to setup the environment and run the tests.
#### Prerequisites
* docker
* docker-compose
#### Run
To execute the tests suites for single node cluster (tcp connection) simply run
npm run test:single
To execute the tests suites for multiple nodes cluster (gossip connection) simply run
npm run test:gossip
To execute the tests suites for multiple nodes cluster (dns discovery connection) simply run
npm run test:cluster
