Can you add tests for data array? recursive and non-recursive

Can you point me to an existing test for a function that I can use as an example? I'm not familiar with the CI project structure.

I added two tests. I don't have much experience with unit tests so please tell me if it seems right.

@Cleric-K Please fix the coding style.
composer cs-fix will fix the errors.
