Is there a way for creating a spring context which can run before all of my junit unit tests which are on different classes?

Question

Sorry I did not research this issue deeply on the internet or on SO. So down voting is welcome. After all I have a feeling this may be a dump question. However I am giving a shot.

I have a project which will contain all of the unit tests. All of the unit tests require a setup which basically creates a jndi namespace. I am doing this with @Before tag on each of my unit test class. So I am doing lots of copy paste which is irritating me a little. Is there a way of creating a singleton class which creates this jndi namespace for all of my unit tests possibly with spring or any other way.

Answer 1

Thanks for the M. Deinum sollution. If he posted the answer I would accept it.

I created a master class like this

import java.io.IOException;
import java.sql.SQLException;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.naming.NamingException;

public class JndiInit{

    @PostConstruct
    public void init() throws IOException, SQLException, NamingException{
        System.out.println("Mastersetup for initializing jndi namespace");
    }

    @PreDestroy
    public void tearDown(){
        System.out.println("Tear down");
    }

}

My unit tests uses a spring context Test 1 :

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/testContext.xml")
public class Test1{


    @Test
    public void test(){
        System.out.println("test 1");
    }

}

And Test2

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/testContext.xml")
public class Test2 {

    @Test
    public void test(){
        System.out.println("test 2");
    }
}

And my spring context is like :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean class="tr.com.mhrs.test.base.jndifactory.JndiInit">

    </bean>
</beans>

It successfully achieved what I want.

Mastersetup for initializing jndi namespace
test 1
test 2
Tear down

Thanks guys.
