    <p>How is it supposed to build some tests with the repository approach in Spring Data MongoDB? I would like to set the test database for my tests since I don't want to use the production database for this purpose. It should be probably possible but I have no idea. This is my application context:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xmlns:neo4j="http://www.springframework.org/schema/data/neo4j" xsi:schemaLocation= "http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/data/neo4j http://www.springframework.org/schema/data/neo4j/spring-neo4j.xsd"&gt; &lt;!-- Default bean name is 'mongo' --&gt; &lt;mongo:mongo host="${mongo.host}" port="${mongo.port}"&gt; &lt;mongo:options connections-per-host="8" threads-allowed-to-block-for-connection-multiplier="4" connect-timeout="${mongo.connect-timeout}" max-wait-time="${mongo.max-wait-time}" auto-connect-retry="true" socket-keep-alive="true" socket-timeout="${mongo.socket-timeout}" slave-ok="true" write-number="1" write-timeout="0" write-fsync="true"/&gt; &lt;/mongo:mongo&gt; &lt;bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"&gt; &lt;constructor-arg ref="mongo" /&gt; &lt;constructor-arg name="databaseName" value="${mongo.db}" /&gt; &lt;/bean&gt; &lt;context:component-scan base-package="domain.company.group.project.data.repositories"/&gt; &lt;!-- MongoDB repositories --&gt; &lt;mongo:repositories base-package="domain.company.group.project.data.repositories.mongodb"/&gt; &lt;!-- some other stuff --&gt; &lt;/beans&gt; </code></pre> <p>And let's say I have a simple repository as follows:</p> <pre><code>public interface LocationRepository extends MongoRepository&lt;Location, String&gt;, LocationRepositoryCustom { } </code></pre> <p>where LocationRepositoryImpl is the class implementing all my custom methods for a certain Location (domain object) class. My test class looks like:</p> <pre><code>@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"/test-context.xml"}) public class LocationRepositoryTest { @Autowired private LocationRepository locationRepository; /* Some tests... */ } </code></pre> <p>I have tried to embed a MongoDB instance within my running tests (as explained <a href="http://blog.yohanliyanage.com/2012/11/integration-testing-mongodb-spring-data/" rel="nofollow">here</a>) but it does not work: the connection to the test database is established but the mongo template seems not able to be overwritten as all save methods keep inserting data to the "production" database.</p> <p>I am using Spring 3.2.0 and Spring Data Mongo 1.1.0.RELEASE. I am using Junit for testing.</p> <p>Any suggestions?</p> <p>Thank you in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
