Eclipse插件，用于自动创建Java代码以重现对象的状态，以便在调试时进行快速测试

Question

I'm looking for a plugin for Eclipse to create Java code such as:

Person person = new Person();
person.setName("name");

List<Address> addresses = new ArrayList<Address>();
Address address = new Address("Address");
addresses.add(address);
person.setAddresses(addresses);

, from an object while debugging.

The context is that I want to define some testing to validate converters and as I get those quite complex objects (with lists of lists of objects...) to be converted from a WS, I'ld rather get the Java code automatically while setting a breakpoint and indicating the object I want to process.

Thanks a lot!!

Adding comment as answer as it's quite long.

Yes it's possible to build a plugin like you mentioned, but pure javabeans are quite a smell in OO, so the solution would only apply to a small set of developers (and that's is possible one of the reasons why there's no plugin that does this).

There are even more issues with this (as you mentioned) if the object tree is complex. Where does the plugin stops generating the data? Another issue is that the tests wouldn't be maintainable, imagine the scenario where you do a small change in one of your javabeans , and then need to rewrite N tests to cope with the new property, although the tests have nothing to do with tha property (this is bad test smell)

If you want to build test data check the Test Data Builder Pattern (TDB) . It's a good approach when you can default most of the values and you only need to change a few specific values. It's also quite maintainable and very readable.
