Hi,

I am writing some testcases and I am getting the DBService from the spring bean. But when I run the tests soms of them get the DBservice properly and some others get it null.

The spring.xml is :

<?xml version="1.0" encoding="UTF-8"?>

The class where I am getting the bean is: I have the proper imports here

public class NsmBaseTest {

public NsmBaseTest(){

}

protected NsmDbService nsmDbService;
protected ApplicationContext appContext;
Properties props = null;
Logger logger = null;

@BeforeSuite
public void beforeSuite() {
appContext = new ClassPathXmlApplicationContext("classpath:nsm_bl_qa_test_spring-config.xml");
nsmDbService = (NsmDbService) appContext.getBean("nsmDbService");
logger = Logger.getLogger("NSMT logger");
props = new Properties();
try{
File file = new File("./src/test/resources/test.properties");
props.load(new FileInputStream(file));
}catch(IOException e){
e.printStackTrace();
}
}

@AfterSuite
public void afterSuit(){
appContext = null;
}

protected int getRandomNumber(){
Random random = new Random();
return (random.nextInt());
}
}


There are 2 classes which extend from this NsmBaseTest.
So the problem is nsmDBservice is OK for one of the class and null for the other class. The class which gets NsmDBService as null is not the same each time I run the tests.
The driver class, url, username and password is taken from pom.xml of maven.

Can someone help with this? This is an intermittent issue and needs to be resolved urgently.

Please post code and configuration using the CODE tags so we can read that. The Code button is right there above where you post.

Thanks
