ContextCustomizerFactory (Spring Framework 4.3.30.RELEASE API)

```
public interface ContextCustomizerFactory
```
Factory for creating ContextCustomizers.
Factories are invoked after ContextLoaders have processed context configuration attributes but before the MergedContextConfiguration is created.
By default, the Spring TestContext Framework will use the SpringFactoriesLoader mechanism for loading factories configured in all META-INF/spring.factories files on the classpath.

4.3
