# End-to-End Testing
## Setup with docker
Are you running everything through docker? You're so lucky you don't have to
setup anything!
Just:
```
docker-compose up
```
## Setup without docker
First, you have to tell cypress how to connect to your local neo4j database
among other things. You can copy our template configuration and change the new
file according to your needs.
Make sure you are at the root level of the project. Then:
```bash
# in the top level folder Human-Connection/
$ cp cypress.env.template.json cypress.env.json
```
To start the services that are required for cypress testing, run this:
```bash
# in the top level folder Human-Connection/
$ yarn cypress:setup
```
## Install cypress
Even if the required services for testing run via docker, depending on your
setup, the cypress tests themselves run on your host machine. So with our
without docker, you would have to install cypress and its dependencies first:
```
# in the root folder /
yarn install
```
## Run cypress
After verifying that there are no errors with the servers starting, open another tab in your terminal and run the following command:
```bash
$ yarn cypress:run
```

### Open Interactive Test Console
If you are like me, you might want to see some visual output. The interactive cypress environment also helps at debugging your tests, you can even time travel between individual steps and see the exact state of the app.
To use this feature, instead of `yarn cypress:run` you would run the following command:
```bash
$ yarn cypress:open
```
