junit test cases using embed mongodb de.flapdoodle

I wanted to setup mongodb junit environment with flapdoodle and I got a java.io.IOException when it tries to download the mongodb archive.

I am using:

spring-data-mongodb: 1.6.1.RELEASE
de.flapdoodle.embed.mongo 1.47.3
org.springframework: 4.0.3.RELEASE

I am getting following error:

de.flapdoodle.embed.process.exceptions.DistributionException: java.io.IOException: Could not open inputStream for http://downloads.mongodb.org/win32/mongodb-win32-i386-3.0.2.zip

Caused by: java.net.UnknownHostException: downloads.mongodb.org at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:178)

and also its pointing to mongodb-win32-i386-3.0.2.zip but I am using windows 64 bit.

here is my code

package com.bosch.test;

import junit.framework.TestCase;

    private static final MongodStarter starter = MongodStarter
            .getDefaultInstance();

    private static MongodExecutable mongodExe;
    private static MongodProcess mongod;

    private static MongoClient mongo;


    private DeviceServiceImp deviceServiceImp;

    private MongoTemplate template;

    @BeforeClass
    public static void setUp() throws Exception {
        //System.out.println("1");
        mongodExe = starter.prepare(new MongodConfigBuilder()
                .version(Version.Main.V3_0)
                .net(new Net(12345, Network.localhostIsIPv6())).build());
        System.out.println("2");
        mongod = mongodExe.start();
        System.out.println("3");

        System.out.println("4");
        mongo = new MongoClient("12345", 12345);
        System.out.println("5");

    }

    @AfterClass
    public static void tearDown() throws Exception {
        mongod.stop();
        mongodExe.stop();
    }

    public Mongo getMongo() {
        return mongo;
    }

@Test
public void save(){

   System.out.println("1");

}

}

I think the problem is that you are using a default MongodStarter that is not aware of your proxy configuration (it was my case). You just need to configure the mongodStarter.

Instead of using

private static final MongodStarter starter = MongodStarter
        .getDefaultInstance();

you should have somthing like this in setUp()

Command command = Command.MongoD;

IRuntimeConfig runtimeConfig = new RuntimeConfigBuilder()
        .defaults(command)
        .artifactStore(new ArtifactStoreBuilder()
                .defaults(command)
                .download(new DownloadConfigBuilder()
                        .defaultsForCommand(command)
                        .proxyFactory(new HttpProxyFactory("proxy_host", 8080))))
        .build();

 MongodStarter starter = MongodStarter.getInstance(runtimeConfig);

This configuration is well explained on flapdoodle doc.
