Perago Technical Test
`practical-test.pdf` is the original document which describes the full use case.
The objective is to write a generic library to calculate the difference
between two objects - **original** and **modified** - and return a `diff`
object. The library also has to take into consideration
nested objects, cyclic dependencies and collections such as shown below.
```java
class Bar {
private String name;
private String lastName;
}
class Foo {
// nested object
private Bar bar;
// cyclic dependency on itself
private Foo friend;
// collections
private Set nicknames;
}
```
The library should also be able to restore the **modified** object from its
saved `diff` state.
## Assumptions
- Assumed Java 8 can be used
- Minimal dependencies should be used
- Maven should be used to run the project build
- JUint5 can be used to run the tests
### Run the Tests
```mvn test```
