java - OrientDB Complete Embedded Cluster Test -

i trying create simple test that:

1. activates full server embedded instance (embedded server , distributed configuration)
2. creates initial test database in document mode during first run (create database)
3. opens test database (open database)
4. insert sample record
5. fetch sample record
6. add node , repeat

i can understand steps individually having difficulty piecing simple test case. example, api documentation assumes remote connection. not sure whether applicable method here, , if so, url should specify.

once have completed steps 1, 2 , 3 correctly, should able refer api documentation steps 4 , 5.

as novice user, find difficult interpret documentation in context. or clarification appreciated.

i trying run test junit test. here have far:

public class testorientdb { private static final logger log = logger.getlogger(testorientdb.class);  @test public void testfullembeddedserver() throws exception {     log.debug("connectiong database server...");     string orientdbhome = new file("src/test/resources").getabsolutepath(); //set orientdb home current directory      log.debug("the orientdb home: " + orientdbhome);     system.setproperty("orientdb_home", orientdbhome);      oserver server = oservermain.create();     url configurl = this.getclass().getresource("/orientdb-config.xml");     server.startup(configurl.openstream());     server.activate();      //how create database here?      //how open database use api this: http://orientdb.com/docs/last/document-database.html      //should pause thread keep server active?     log.debug("shutting down orientdb...");     server.shutdown(); }} 

here orientdb-config.xml:

<orient-server> <users>     <user name="root" password="password" resources="*"/> </users> <properties>     <entry value="/etc/kwcn/databases" name="server.database.path"/>     <entry name="log.console.level" value="fine"/> </properties> <handler class="com.orientechnologies.orient.server.hazelcast.ohazelcastplugin">     <parameters>         <!-- node-name. if not set auto generated first time server run -->         <!-- <parameter name="nodename" value="europe1" /> -->         <parameter name="enabled" value="true"/>         <parameter name="configuration.db.default" value="${orientdb_home}/orientdb-config.json"/>         <parameter name="configuration.hazelcast" value="${orientdb_home}/hazelcast.xml"/>     </parameters> </handler> 

here hazelcast.xml:

here orientdb-config.json:

here output:

i suggest take @

https://github.com/orientechnologies/orientdb/blob/2.1.x/distributed/src/test/java/com/orientechnologies/orient/server/distributed/abstractserverclustertest.java

it's base class of orientdb distributed tests. class hierarchy seems quite complex, in end instantiates multiple servers , delegates subclasses test operations against them.

you can check

https://github.com/orientechnologies/orientdb/blob/2.1.x/distributed/src/test/java/com/orientechnologies/orient/server/distributed/hatest.java

that 1 of subclasses. copy or extend , implement own logic in executetest() method.

about questions:

how create database here?

as normal plocal db:

new odatabasedocumenttx("plocal:...").create() 

or

new orientgraph("plocal:...") 

//how open database use api this:

same above:

new odatabasedocumenttx("plocal:...").open("admin", "admin"); 

//should pause thread keep server active?

there no need pause thread, server creates non-daemon threads, remain active. make sure someone, @ end of tests, invokes server.shutdown() (even thread)
