Question: For example, now in each test class I have to do

```
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)

```

I want to get rid of 

```
 @ContextConfiguration(loader=AnnotationConfigContextLoader.class)

```

and want Spring to scan all the beans in my project.

How can I do that?

Answer: 
If you have your spring configuration in an xml file you would use something like:

```
@ContextConfiguration(locations="classpath:applicationContext.xml")

```

If you use Java Config then you would use 

```
@ContextConfiguration(classes=Config.class)

```

I used generic names in the above samples, you'll of course need to adapt to your project's configuration.

In both cases Spring's component scanning will need to be enabled for Spring to pickup the annotated classes.
You can also simply add `@SpringBootTest` if using Spring Boot.
