| Some test helpers such as `EqualsTester` require a terminating method call to be | |
| of any use. | |
| ```java | |
| @Test | |
| public void string() { | |
| new EqualsTester() | |
| .addEqualityGroup("hello", new String("hello")) | |
| .addEqualityGroup("world", new String("world")) | |
| .addEqualityGroup(2, new Integer(2)); | |
| // Oops: forgot to call `testEquals()` | |
| } | |
| ``` |
