In order for the unit test to run a batch job, the framework must load the job's ApplicationContext. Two annotations are used to trigger this:

@RunWith(SpringJUnit4ClassRunner.class): Indicates that the class should use Spring's JUnit facilities

@ContextConfiguration(locations = {...}): Indicates which XML files contain the ApplicationContext.

See more at this official documentation.
