## Overview

Integration tests in Istio are essential for ensuring that various components work together as expected. Depending on the component you are testing, you may need to add your tests to different folders within the `tests/integration` directory. This document will guide you through the process of adding integration tests and understanding the setup requirements.

    You could have custom internal logic to separate it by colon characters (`:`) or
    similar, and get the two parts `items` and `read`. Many applications do that to
    group and organize permissions, you could do it as well in your application, just
    know that that it is application specific, it's not part of the specification.
