Creating test data using ElasticObject

For a recent project I had to write a lot of data-oriented tests. This required me to populate the domain model with lot’s of test data.

  • A hierarchical way to maintain loosely typed data.

I used it to create a whole object hierarchy in a very simple way, like this:
