intellij idea - Spring Data neo4j JUnit4 setup -

i confess total newbie @ java way of doing things , totally lost trying simple unit test running.

i building data access library , want unit test it. using spring data neo4j 4.0.0.build-snapshot because need connect remote neo4j server in real world.

after battling errors day @ point have test class:

@runwith(springjunit4classrunner.class) @componentscan(basepackages = {"org.mystuff.data"}) @contextconfiguration(classes={neo4jtestconfiguration.class}) public class personrepositorytest {     @autowired     personrepository personrepository;     protected graphdatabaseservice graphdb;      @before     public void setup() throws exception {         graphdb = new testgraphdatabasefactory().newimpermanentdatabase();     }      @after     public void teardown() {         graphdb.shutdown();     }      @test     public void testcreateperson() throws exception {         assertnotnull(personrepository);         person p = new person("test", "user");         personrepository.save(p);     } } 

neo4jtestconfiguration.java

@configuration @enableneo4jrepositories(basepackages = "org.mystuff.data") @enabletransactionmanagement public class neo4jtestconfiguration extends neo4jconfiguration {     @bean     public sessionfactory getsessionfactory() {         return new sessionfactory("org.mystuff.data");     }      @bean     public neo4jserver neo4jserver() {         // return here? want in-memory database         return null;     }      @bean     @scope(value = "session", proxymode = scopedproxymode.target_class)     public session getsession() throws exception {         return super.getsession();     } } 

when running tests personrepository.save() throws , exception 'no scope registered scope "session"' don't know if need configuration class test class won't work without because spring needs @contextconfiguration , want di niceness spring provides (amongst other things).

how can tests work spring?

you can use inprocessserver in-memory database:

@bean public neo4jserver neo4jserver() {     return new inprocessserver(); } 

omit session scope test isn't running in web container. example: https://github.com/neo4j-examples/sdn4-cineasts/blob/4.0-rc1/src/test/java/org/neo4j/cineasts/persistencecontext.java

this require dependencies described in question: spring data neo4j 4.0.0.m1 test configuration

in test class personrepositorytest, don't need construct instance of database, tests run against same inprocessserver. here's example: https://github.com/neo4j-examples/sdn4-cineasts/blob/4.0-rc1/src/test/java/org/neo4j/cineasts/domain/domaintest.java
