Integration Testing
===================
To run integration tests, you have to specify the druid cluster the
tests should use.
Druid comes with the mvn profile integration-tests
for setting up druid running in docker containers, and using that
cluster to run the integration tests.
To use a druid cluster that is already running, use the
mvn profile int-tests-config-file, which uses a configuration file
describing the cluster.
Integration Testing Using Docker
-------------------
## Installing Docker
Please refer to instructions at [https://github.com/druid-io/docker-druid/blob/master/docker-install.md](https://github.com/druid-io/docker-druid/blob/master/docker-install.md).

Running a Test That Uses Hadoop
-------------------
The integration test that indexes from hadoop is not run as part
of the integration test run discussed above. This is because druid
test clusters might not, in general, have access to hadoop.
That's the case (for now, at least) when using the docker cluster set
up by the integration-tests profile, so the hadoop test
has to be run using a cluster specified in a configuration file.
The data file is
integration-tests/src/test/resources/hadoop/batch_hadoop.data.
Create a directory called batchHadoop1 in the hadoop file system
(anywhere you want) and put batch_hadoop.data into that directory
(as its only file).
Add this keyword to the configuration file (see above):
```
"hadoopTestDir": "<name_of_dir_containing_batchHadoop1>"
```
Run the test using mvn:
```
mvn verify -P int-tests-config-file -Dit.test=ITHadoopIndexTest
```
In some test environments, the machine where the tests need to be executed
cannot access the outside internet, so mvn cannot be run. In that case,
do the following instead of running the tests using mvn:
### Compile druid and the integration tests
On a machine that can do mvn builds:
```
cd druid
mvn clean package
cd integration_tests
mvn dependency:copy-dependencies package
```
### Put the compiled test code into your test cluster
Copy the integration-tests directory to the test cluster.
### Set CLASSPATH
```
TDIR=<directory containing integration-tests>/target
VER=<version of druid you built>
export CLASSPATH=$TDIR/dependency/*:$TDIR/druid-integration-tests-$VER.jar:$TDIR/druid-integration-tests-$VER-tests.jar
```
### Run the test
```
