Cassandra integration test example
This project demonstrates how you can write unit and integration tests for code that works with Cassandra and have coverage report for it.
git clone https://github.com/ash2k/cassandra-integration-test.git
cd ./cassandra-integration-test
mvn clean verify
After this you'll get ./target/site/jacoco directory with coverage report.
Unit tests are written with help of TestNG and Mockito and run by maven-surefire-plugin. Nothing special here.
Integration tests are also powered by TestNG which is executed by maven-failsafe-plugin in this case.
Network ports are reserved by build-helper-maven-plugin's reserve-network-port goal. This lowers the probability that build will fail because of used network ports (e.g. Cassandra already runs on building host).
Cassandra node is started at the pre-integration-test Maven build lifecycle phase and is stopped at post-integration-test phase. This is done by cassandra-maven-plugin's start and stop goals respectively. Also, before the integration tests are run, Cassandra's data directory is wiped out by execution of delete goal of cassandra-maven-plugin.
Code coverage report is generated by jacoco-maven-plugin.
