# Istio Integration Tests

This document highlights the different integration test setups and architectural configurations for setting up the tests. It also provides guidelines for adding integration tests to the Istio project, specifically focusing on the differences between adding tests to the various folders under `tests/integration`. It also explains the implications of using the main test setup in each folder.
