Data Providers
A test method can accept any parameter. These parameters can be provided by a data provider method (provider () in the following example).
The data provider method is declared with @dataprovider.
A data provider method must be public, can return a set of arrays, or it can return an object that inherits from the iterator interface and produces an array based on each step iteration.
For each array is part of the collection, and the test method invokes the array contents as its arguments.

Array (0, 0, 0),
Array (0, 1, 1),
Array (1, 0, 1),

failures!
Tests:4, Assertions:4, failures:1.
In the above example, the fourth set of data tests did not pass.
* When a test accepts parameters from both the @dataprovider method and one or more @depends methods, the parameters from the data provider will precede the parameters from the @depends.
