Using the spot data table to populate objects

I am using Spock for the first time. Since we use a complex domain model, it would be convenient to have a mechanism that allows me to create complete objects from data given by spot tables. I do not want to give all the values ​​every time, I just want to set the values ​​to the given in the datable. Therefore, default values ​​must be defined somewhere.

Yes, I know that I can write on my own, but maybe there is a ready-made solution.

Example

class A {
   String name
   int age
}

Point table

id | givenA                     | ...
1  | [name: "Michael"]          | ...
2  | [name: "Thomas", age: 45 ] | ...
  • => A.name = "Michael", A.age = defined default value somewhere
  • => A.name = "Thomas" A.age = 45 (because I am overwriting the default value)

Not sure what exactly you are looking for, but instead [name: "Thomas", age: 45]you can write new A(name: Thomas, age: 45). If you want to reuse appliances, you can do:

where:
[id, givenA] << staticUtilityMethodThatReturnsCollectionOfTwoElementCollections()

You can also create a small API (or use the Groovy collection built-in operations) to change the default values.
