Application crashes while doing unit testing from framework project

I have created a framework project to include all the business logic of my application. So that, the core data model also moved to the framework project. Now I have a few XCTestCase classes to do unit testing for the manager and module classes in the framework. These classes have core data operation. So, during the unit testing, those classes refers to DBManager class. I am getting crash in this case, occurring at the creation of persistent model. At the same time when I used the same unit test cases in the main project, everything is working fine.One thing I mainly noted is that, the storeURL creating at the time of persistent creation is different while running main project and unit test cases in the framework. Following are the storeURL created. file:///Users/Gowtham/Library/Developer/CoreSimulator/Devices/F7DB4F9B-D323-4978-A816-B5363F26BE32/data/Containers/Data/Application/92F08534-F5AD-4B4B-B1A3-D3CEF17758C0/Documents/IHA.sqlite [Main project]

Following is the exception showing in the console.

Can anyone give me suggestion for the proper way of writing unit test cases which communicate with core data in a Framework project?
