Test Data Supplier (TestNG DataProvider wrapper)

Test Data Supplier (TestNG DataProvider wrapper)

If you are a big fan of Stream and Collection API for data manipulation in the modern Java world, give a shot to this library that contains TestNG DataProvider wrapper (as of writing this article, the latest version is based on TestNG 7.4.0) which helps to supply test data in a more flexible way.

Supported return types

• Collection
• Map
• Entry
• Object[]
• double[]
• int[]
• long[]
• Stream / StreamEx
• Tuple
• A single Object of any common or custom type

As it can return StreamEx, it gives you more power to play with flatmap, indices, transposing, etc.
