| Making a `@Mock` instance `static` will share the state across tests and can | |
| make them order dependent and/or unclear to reader/maintainer. Removing | |
| `static`, will ensure fresh mock instances are used for each tests. | |
| Additionally, if the `@Mock` instance is marked as `static` to make it | |
| serializable, there is a cleaner way to do it : | |
