# Integration Tests ## Overview The integration tests use [Testcontainers](https://www.testcontainers.org/) to provide a sane default for developers who have installed Docker. Testcontainers support can be disabled by setting the system property `elasticsearch.testcontainers.enabled` to something other than `true`. If Testcontainers are disabled, the endpoint will need to be configured. It can be set manually with the system property `elasticsearch.endpoint`. The default value is `http://localhost:9200`. ## Maven Profiles * `integration-tests` * `elasticsearch6` * `elasticsearch7` ## Configurable System Properties * `elasticsearch.endpoint` - Manually configure the endpoint root for a non-Docker version of Elasticsearch, * `elasticsearch.testcontainers.enabled` - Set to anything other than `true` to disable Testcontainers and use a non-Docker version of Elasticsearch. * `elasticsearch.elastic_user.password` - Set the Elasticsearch `elastic` user's password. When Testcontainers are enabled, this sets up the Docker container and the rest clients for accessing it within the tests. When Testcontainers are disabled, it needs to be set to whatever password is used on the external Elasticsearch node or cluster. ## Maven Run Examples Elasticsearch 8.X is the current default version of Elasticsearch when Testcontainers are used. An example run of the integration tests with Elasticsearch 7 support would be like this: `mvn -Pintegration-tests,elasticsearch7 --fail-at-end clean install` An example using a non-Docker version of Elasticsearch: `mvn -Pintegration-tests --fail-at-end -Delasticsearch.testcontainers.enabled=false -Delasticsearch.elastic_user.password=s3cret1234 clean install` ## Modules with Integration Tests (using Testcontainers) - [Elasticsearch Client Service](nifi-elasticsearch-client-service) - [Elasticsearch REST API Processors](nifi-elasticsearch-restapi-processors) ## Misc Integration Tests with Testcontainers currently only uses the `amd64` Docker Images. `elasticsearch6` is known to **not** work with `arm64` machines (e.g. Mac M1/M2), but other Elasticsearch images (e.g. 7.x and 8.x) appear to work. Explicit `arm64` architecture support may be added in future where the Elasticsearch images exist.
