When you are unit testing, it is sometimes necessary to supplement an object with dummy data. Unfortunately, to fill a large object manually, it crawls a lot of time and work. Fortunately, there is a tool that saves us the time and work!
At https://code.google.com/p/dummycreator/wiki/DummyCreator, you can find a java library that fills an object with dummy data by typing one line of code.
If you use Maven, you can add the following dependency:
|
1 2 3 4 5 6 |
<dependency> <groupId>de.dev-eth0.dummycreator</groupId> <artifactId>dummy-creator</artifactId> <version>1.2</version> <scope>test</scope> </dependency> |
Example
In this example, we want to add dummy data for an object User.
|
1 2 3 4 5 6 7 8 9 |
public class User { private Long id; private String firstName; private String lastName; private String email; //getters & setters... } |
Now, to fill this object, type the following code:
|
1 |
User user = new DummyCreator().create(User.class); |
It’s easy as that! Enjoy! 😀
It has been a while, but the dummycreator project has reincarnated into the modern age as “lorem-ipsum-objects”, over at https://github.com/bbottema/lorem-ipsum-objects.
