# Testing

Building regular unit tests would require to create a mock
elasticsearch cluster, which is too much a chrore for a one man
show. Running a regular elasticsearch cluster on Codeberg CI is not
economically reasonable.

Therefore I run tests manually. Here's how.

# Dependencies

The following is required:

- linux, any distro will do
- docker in a decent version
- [mosscap](https://codeberg.org/scip/mosscap)

# Docker

There's a ready to use docker compose file, which fires up an
elasticsearch cluster with 3 nodes. To start it manually just execute
`make up`.

When it's up and running it should look like this:

```console
NAMES     STATUS                   PORTS
t-es03-1  Up 16 minutes (healthy)  9200/tcp, 9300/tcp
t-es02-1  Up 16 minutes (healthy)  9200/tcp, 9300/tcp
t-es01-1  Up 16 minutes (healthy)  0.0.0.0:9200->9200/tcp, [::]:9200->9200/tcp, 9300/tcp
```

There's an esctl config file `cluster.yaml`, which you can use to
access that elasticsearch cluster, e.g.:

```console
esctl -c cluster.yaml cluster status 
DOCKER/DOMDOC              STATUS
Cluster Name               domdoc
ES Status                  green
ES Version                 9.4.2
Is Leader                  false
Active Shards              8
Active Primary Shards      4
Unassigned Shards          0
Unassigned Primary Shards  0
Pending Tasks              0
Nodes                      3
Red Indices                0
Long Running Tasks         0
```

# Automated Tests

To execute the automated tests, just execute `make test`. This boots
up the elasticsearch containers, waits until they are up and running,
creates data on it and queries it.

# Cleanup

To just clean up the elasticsearch cluster run `make clean`.

To remove everything, run `make clean-docker`.
