+### Xcode Test Plans
+For granular control (enabling/disabling specific tests or trying different configurations), use **Xcode Test Plans**:
+
+1. **Create a Test Plan**:
+   - Go to **Product > Test Plan > New Test Plan...**
+   - Save it in your `Tests/` directory as `LocalData.xctestplan`.
+2. **Configure Tests**:
+   - Open the `.xctestplan` file.
+   - You will see a list of all test targets, classes, and individual test methods.
+   - Use the **check/uncheck** boxes to include or exclude specific tests.
+3. **Run the Plan**:
+   - Hold down the **Play** button for the test action or go to **Product > Test > [Plan Name]**.
+   - You can also run it via terminal: `xcodebuild test -plan LocalData`.
+
+> [!TIP]
+> Test plans are excellent for CI/CD environments where you might want to run a "Smoke Test" plan (subset of tests) or a "Full Integration" plan.
