+# Test Data Driver Component
+
+## Detailed Description
+The **Test Data Driver** acts as a mock input source for the ASTRAL-Next system in the sandbox/validation environment. It replaces the real hardware camera drivers. It is responsible for iterating through the provided dataset (`AD*.jpg`), managing the simulation clock, and providing the "Ground Truth" camera intrinsics.
+
+It serves as the primary feeder for Integration Tests, ensuring the system can be validated against a known sequence of events.
+
+## API Methods
+
+### `initialize_source`
+- **Input:** `source_path: str`, `camera_config_path: str`
+- **Output:** `bool`
+- **Description:** Opens the image directory. Loads the camera intrinsic parameters (K matrix, distortion model) from the config file. Prepares the iterator.
+- **Test Cases:**
+    - Valid path -> Returns True, internal state ready.
+    - Invalid path -> Returns False, logs error.
+
+### `get_next_frame`
+- **Input:** `void`
+- **Output:** `FrameObject | None`
+- **Description:** Retrieves the next available image from the sequence.
+    - **Structure of FrameObject:**
+        - `image_raw`: np.array (Original resolution)
+        - `timestamp`: float
+        - `frame_id`: int
+        - `intrinsics`: CameraIntrinsics object
+- **Test Cases:**
+    - End of sequence -> Returns None.
+    - Corrupt image file -> Skips or raises error.
+
+### `get_intrinsics`
+- **Input:** `void`
+- **Output:** `CameraIntrinsics`
+- **Description:** Returns the loaded camera parameters (fx, fy, cx, cy, distortion).
+- **Test Cases:**
+    - Check against known values in `data_parameters.md`.
+
+## Integration Tests
+- **Sequence Replay:** Point to `docs/00_problem/input_data`, iterate through all `AD*.jpg` files. verify correct ordering and total count (60 frames).
+
+## Non-functional Tests
+- **File I/O:** Efficiently read large files from disk without blocking the test runner for extended periods.
