```
public class BDDAssertions
extends Assertions
```
BDD style entry point for assertion methods for different data types. Each method in this class is a static factory for the type-specific assertion objects. The purpose of this class is to make test code more readable.
The difference with Assertions class is that entry point methods are named then instead of assertThat.
For example:
```
  @Test
 public void bdd_assertions_examples() {

   //given
   List<BasketBallPlayer> bulls = new ArrayList<BasketBallPlayer>();

   //when
   bulls.add(rose);
   bulls.add(noah);

   then(bulls).contains(rose, noah).doesNotContain(james);
 }
```
