Exception while connecting to MongoDB using spring data

[Karthik]

I am trying to connect to a MongoDB instance from my testcases. I am getting the below error...

Mongo process is up and running. Any thoughts on the exception reason?

What about your webapp? Can it connect to localhost:12346/your_db ?

How did you configure mongodb for your tests? Do you have a separate app context file?

Yep. I am able to connect from the webapp (localhost:27017).

I have a separate config file for test cases with different port.

I am starting the mongo process before the test class is executed and stopping the process after test class execution. I am getting the below error, if i run more than 1 test class. If i run the test classes individually, they are working fine.

[Octavian Covalschi]

Hm..i took a different approach, I have a db_test in my main instance... but your way should work too.

I suspect that other classes are trying to start your test instance while it's being shut down..  How are you running your tests? ant, maven, gradle? I wonder if you could move to a higher level your start/stop operations... I mean for all tests and not each test class.

I am running my tests using maven. Yeah...i am wondering the same. If the Port is not yet released for the next test connection. I am trying to add an artificial wait state between each test case and see, if that helps.

Thanks for the response.
