## Testing
66+
67+
To setup an integration test environment, make sure you have an etcd instance running on the standard port, without ssl: http://localhost:2379
68+
69+
On ubuntu, simply run
70+
71+
```
72+
sudo apt-get install etcd-server etcd-client
73+
```
74+
75+
Create a root account and enable authentication
76+
77+
```
78+
etcdctl --endpoints=http://localhost:2379 user add root
79+
Password of root:
80+
```
81+
enable authentication:
82+
```
83+
etcdctl --endpoints=http://localhost:2379 auth enable
84+
```
85+
86+
For your convenience, terraform files are included in the folder tests/terraform/
87+
88+
In the file ```tests/terraform/main.tf``` replace the password with the one you just used when creating the root user.
89+
90+
in the tests/terraform folder, init terraform:
91+
92+
```
93+
terraform init
94+
```
95+
to see what changes will be made:
96+
```
97+
terraform plan
98+
```
99+
to execute the changes, and create the keys:
100+
```
101+
terraform apply
102+
```
103+
104+
then run the tests from the src folder
