Running elastic search integration test throwing an exception? - spring

Question

Hi I am having a spring boot application that uses cassandra as the database. Recently i got a requirement to support elastic search in the application . so i have created a class AbstractElasticSearchTest that will start an embedded elastic search instance. I have written a small junit test however running it throws exception related to cassandra.
so following is my base AbstractElasticSearchTest class.
#ActiveProfiles(JHipsterConstants.SPRING_PROFILE_TEST)
public class AbstractElasticSearchTest {
private static EmbeddedElastic embeddedElastic;
#BeforeClass
public static void startElasticServer() throws FileNotFoundException, IOException, InterruptedException {
embeddedElastic = EmbeddedElastic.builder().withElasticVersion("6.6.1")
.withSetting(PopularProperties.TRANSPORT_TCP_PORT, 9350)
.withSetting(PopularProperties.CLUSTER_NAME, "my_cluster")
.withStartTimeout(2, TimeUnit.MINUTES)
.withIndex("cars", IndexSettings.builder()
.withType("car", getSystemResourceAsStream())
.build())
.build()
.start();
}
private static InputStream getSystemResourceAsStream() throws FileNotFoundException {
ClassLoader classloader = Thread.currentThread().getContextClassLoader();
InputStream is = classloader.getResourceAsStream("config/elasticsearch/car-mapping.json");
return is;
}
#AfterClass
public static void close() {
embeddedElastic.stop();
}
}
the junit integration test is as follow.
#RunWith(SpringRunner.class)
#SpringBootTest(classes = PrimecastApp.class)
public class PerformanceReportingIntTest extends AbstractElasticSearchTest {
#Test
public void test() {
}
}
The exception that i recieves is below.

i think it is more related to spring boot configuration . appreciate if you can throw any insight into it .
[ I am sharing the code in git hub
git clone https://github.com/prasanthmp500/mep.git
please checkout the branch ENG-170-performance-reports and run mvn clean test under api folder . ]
i have a cassandra embedded instance that is run from a class
/**
* Base class for starting/stopping Cassandra during tests.
*/
#ActiveProfiles(JHipsterConstants.SPRING_PROFILE_TEST)
public class AbstractCassandraTest {
public static final String CASSANDRA_UNIT_KEYSPACE = "cassandra_unit_keyspace";
private static final String CASSANDRA_UNIT_RANDOM_PORT_YAML = "cassandra-random-port.yml";
public static final String CQL_DIR = "config/cql/changelog/";
// Not adding the changelog directory as when loading the resources this is then the default directory and it's preferable to
// load all data from the "config/cql/changelog/" first before looking to the test resources.
public static final String TEST_CQL_DIR = "config/cql/";
private static final long CASSANDRA_TIMEOUT = 30000L;
private static boolean started = false;
private static Session session;
private static CQLDataLoader dataLoader;
#BeforeClass
public static void startServer() throws TTransportException, ConfigurationException, IOException, URISyntaxException {
if (!started) {
EmbeddedCassandraServerHelper.startEmbeddedCassandra(CASSANDRA_UNIT_RANDOM_PORT_YAML, CASSANDRA_TIMEOUT);
Cluster cluster = new Cluster.Builder().addContactPoints("127.0.0.1").withPort(getNativeTransportPort())
.build();
session = cluster.connect();
String createQuery = "CREATE KEYSPACE " + CASSANDRA_UNIT_KEYSPACE + " WITH replication={'class' : 'SimpleStrategy', 'replication_factor':1}";
session.execute(createQuery);
String useKeyspaceQuery = "USE " + CASSANDRA_UNIT_KEYSPACE;
session.execute(useKeyspaceQuery);
dataLoader = new CQLDataLoader(session);
applyScripts(dataLoader, CQL_DIR, "*.cql");
started = true;
}
}
public static void applyScript(String dir, String cql) throws IOException, URISyntaxException {
applyScripts(dataLoader, dir, cql);
}
private static void applyScripts(CQLDataLoader dataLoader, String cqlDir, String pattern) throws IOException, URISyntaxException {
URL dirUrl = ClassLoader.getSystemResource(cqlDir);
if (dirUrl == null) { // protect for empty directory
return;
}
List<String> scripts = new ArrayList<>();
try (DirectoryStream<Path> stream = Files.newDirectoryStream(Paths.get(dirUrl.toURI()), pattern)) {
for (Path entry : stream) {
scripts.add(entry.getFileName().toString());
}
}
Collections.sort(scripts);
for (String fileName : scripts) {
dataLoader.load(new ClassPathCQLDataSet(cqlDir + fileName, false, false, CASSANDRA_UNIT_KEYSPACE));
}
}
}
so most of my tests run extends like this
#RunWith(SpringRunner.class)
#SpringBootTest(classes = PrimecastApp.class)
public class AccountResourceIntTest extends AbstractCassandraTest {
}
so probably i should rewrite this class PerformanceReportingIntTest to extend AbstractCassandraTest and inject an instance of AbstractElasticSearchTest into the PerformanceReportingIntTest. not sure if i am going in the right direction.
thank you
