B.3. Spock Genesis
Spock Genesis (https://github.com/Bijnagte/spock-genesis) is a meta data-generator library for parameterized Spock tests. I briefly mentioned it at the end of chapter 5. At its core, Spock Genesis can be used as a data source for Spock tests. The following listing is an example directly from Spock Genesis’ own samples.
Listing B.1. Creating test data with Spock Genesis
Spock Genesis can work as an abstraction over existing data generators, as it can also do the following:
- Compose existing generators into new ones
- Filter existing generators using predicates/closures
- Randomize or order the output for other generators
