java.lang.Object
- org.junit.runner.notification.Failure

All Implemented Interfaces:
Serializable
```
public class Failure
extends Object
implements Serializable
```
A Failure holds a description of the failed test and the exception that was thrown while running it. In most cases the Description will be of a single test. However, if problems are encountered while constructing the test (for example, if a BeforeClass method is not static), it may describe something other than a single test.
