```
## Testing
### Execute short tests:
execute `make short-test`
### Execute long tests:
As Telegraf collects metrics from several third-party services it becomes a
difficult task to mock each service as some of them have complicated protocols
which would take some time to replicate.
To overcome this situation we've decided to use docker containers to provide a
fast and reproducible environment to test those services which require it.
For other situations
(i.e: https://github.com/influxdb/telegraf/blob/master/plugins/redis/redis_test.go )
a simple mock will suffice.
To execute Telegraf tests follow these simple steps:
- Install docker compose following [these](https://docs.docker.com/compose/install/) instructions
- NOTE: mac users should be able to simply do `brew install boot2docker`
and `brew install docker-compose`
- execute `make test`
### Unit test troubleshooting:
Try cleaning up your test environment by executing `make test-cleanup` and
re-running

# Kafka Consumer
The [Kafka](http://kafka.apache.org/) consumer plugin polls a specified Kafka
topic and adds messages to InfluxDB. The plugin assumes messages follow the
line protocol. [Consumer Group](http://godoc.org/github.com/wvanbergen/kafka/consumergroup)
is used to talk to the Kafka cluster so multiple instances of telegraf can read
from the same topic in parallel.
## Testing
Running integration tests requires running Zookeeper & Kafka. The following
commands assume you're on OS X & using [boot2docker](http://boot2docker.io/).
To start Kafka & Zookeeper:
```
docker run -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=`boot2docker ip` --env ADVERTISED_PORT=9092 spotify/kafka
```
To run tests:
```
ZOOKEEPER_PEERS=$(boot2docker ip):2181 KAFKA_PEERS=$(boot2docker ip):9092 go test
```
