Add more pagination tests

• Test custom page size.
• Just test all possible options.

Is it working pagination? I am trying it on my project and the query param "page_size" doesn't seem to affect at all the pagination. I always receive 10 elements.

Thanks for the work and effort to keep up this project : )

@robertofd1995:

It does work. Read the docs and check the example project.

If you have the example project running, the following shall be working:

• 3 results per page
• 20 results per page

Please, take time to read the docs and examples thoroughly before you raise questions.
