JUNIt中的测试应用程序

Question

I'm getting errors while testing my application in JUNIT

java.lang.IllegalStateException: Failed to load ApplicationContext

as i created classes for Configuration and not applicationContext files it is messing up this error.

Below is classes and DAO file.

WebAppContext.java

        assertTrue(true);
    }
    @Test
    public void testRemoveUser() {

        assertTrue(true);

    }

}

As im using classes to configure and not XML files.Is there any way to overcome this error No qualifying bean of type [org.hibernate.SessionFactory] found for dependency.

Failed to load ApplicationContext is one of the base error for this.This is of full code details with the configuration files

WebAppContext and TestContext is of Configuration files

UesrTestDAO is the DAO method where my JUNIT works
