Spring Boot Data Embedded Cassandra

Question

In my Spring Boot 1.5.1 application I'm going to write unit/integration tests for Cassandra related logic.

I have added folowing Maven dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-cassandra</artifactId>
</dependency>

The default Spring Boot Cassandra configuration is going to connect with a real Cassandra DB server.

Is there any options in Spring/Spring Boot in order to configure my tests to use embedded Cassandra server ? If so, could you please show the required configuration.

Answer 1

We use on the project Cassandra + Spring Boot. Here are the steps which worked for us:

a) Configure you test like this

import org.cassandraunit.spring.CassandraDataSet;
import org.cassandraunit.spring.CassandraUnitDependencyInjectionTestExecutionListener;
import org.cassandraunit.spring.CassandraUnitTestExecutionListener;
import org.cassandraunit.spring.EmbeddedCassandra;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = TestConfiguration.class)
@TestExecutionListeners(listeners = {
    CassandraUnitDependencyInjectionTestExecutionListener.class,
    CassandraUnitTestExecutionListener.class,
    ServletTestExecutionListener.class,
    DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class
})
@EmbeddedCassandra(timeout = 60000)
@CassandraDataSet(value = {"bootstrap_test.cql"}, keyspace = "local_test")
public abstract class BaseTest {

b) in your src/test/resources/application.properties, add this (please note, embedded cassandra starts on port 9142, but not on default 9042)

spring.data.cassandra.port=9142
spring.data.cassandra.keyspace-name=local_test

c) Create empty file bootstrap_test.cql in src/test/resources

d) Add to your pom.xml

    <dependency>
        <groupId>org.cassandraunit</groupId>
        <artifactId>cassandra-unit-spring</artifactId>
        <version>${cassandra-unit.version}</version>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.cassandraunit</groupId>
                <artifactId>cassandra-unit</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.cassandraunit</groupId>
        <artifactId>cassandra-unit-spring</artifactId>
        <version>${cassandra-unit.version}</version>
    </dependency>

This should be enough to run your tests with Embedded Cassandra. Hope it helps.
