+# Feature Integration Tests
+
+This directory contains Feature Integration Tests for the S-CORE project. It includes both Python test cases and Rust test scenarios to validate features work together.
+
+## Structure
+
+- `python_test_cases/` — Python-based integration test cases
+  - `conftest.py` — Pytest configuration and fixtures
+  - `fit_scenario.py` — Base scenario class
+  - `requirements.txt` — Python dependencies
+  - `BUILD` — Bazel build and test definitions
+  - `tests/` — Test cases (e.g., orchestration with persistency)
+- `rust_test_scenarios/` — Rust-based integration test scenarios
+  - `src/` — Rust source code for test scenarios
+  - `BUILD` — Bazel build definitions
+
+## Running Tests
+
+### Python Test Cases
+
+Python tests are managed with Bazel and Pytest. To run the main test target:
+
+```sh
+bazel test //feature_integration_tests/python_test_cases:fit
+```
+
+### Rust Test Scenarios
+
+Rust test scenarios are defined in `rust_test_scenarios/src/scenarios`. Build and run them using Bazel:
+
+```sh
+bazel build //feature_integration_tests/rust_test_scenarios
+```
+
+```sh
+bazel run //feature_integration_tests/rust_test_scenarios -- --list-scenarios
+```
+
+## Updating Python Requirements
+
+To update Python dependencies:
+
+```sh
+bazel run //feature_integration_tests/python_test_cases:requirements.update
+```
