+# GameRecord Snapshot Tests
+
+This directory contains snapshot tests for `GameRecord.fromSgf` and `GameRecord.fromGib` methods.
+
+## How It Works
+
+The tests automatically discover all `.sgf` and `.gib` files in the `fixtures/` directory and validate them against their corresponding snapshot JSON files. **No need to write new test cases** - just add your file and regenerate snapshots!
+
+## Structure
+
+- `fixtures/` - Test data files
+  - `*.sgf` - Sample SGF game files
+  - `*.gib` - Sample GIB game files
+  - `snapshots/` - Expected output JSON files for comparison
+
+## Running Tests
+
+Run all snapshot tests:
+```bash
+flutter test test/game_record_snapshot_tests/
+```
+
+Or run all tests:
+```bash
+flutter test
+```
+
+## Regenerating Snapshots
+
+If you modify the `GameRecord` parsing logic or want to update the expected outputs:
+
+```bash
+dart run test/game_record_snapshot_tests/generate_snapshots.dart
+```
+
+The generator automatically discovers all `.sgf` and `.gib` files in the fixtures directory.
+
+This will regenerate all snapshot JSON files in `fixtures/snapshots/`.
+
+## Snapshot Format
+
+Each snapshot is a JSON file containing:
+```json
+{
+  "type": "GameRecordType.sgf",
+  "moveCount": 14,
+  "moves": [
+    {
+      "color": "B",  // "B" for black, "W" for white
+      "row": 4,
+      "col": 4
+    },
+    ...
+  ]
+}
+```
+
+## Adding New Test Cases
+
+1. Add a new `.sgf` or `.gib` file to `test/game_record_snapshot_tests/fixtures/`
+2. Run the generator: `dart run test/game_record_snapshot_tests/generate_snapshots.dart`
+3. Run tests to verify: `flutter test test/game_record_snapshot_tests/`
+
+**That's it!** The test framework automatically discovers and tests your new file.
