DataProvider

```
@Retention(RUNTIME)
@Target(METHOD)
@Documented
public @interface DataProvider
```
Mark a method as supplying data for a test method.
The name defaults to the name of the annotated method.
The annotated method must return any of the following:
- Object[][] or Iterator<Object[]>, where each Object[] is assigned to the parameter list of the test method.
- Object[] or Iterator<Object>, where each Object is assigned to the single parameter of the test method.
The @Test method that wants to receive data from this DataProvider needs to use a Test.dataProvider() name equal to the name of this annotation.
