Once you’ve configured your goals and constraints and your initial Fulfillment Health Score has been calculated, fabric’s real-time testing engine will begin recommending optimized order fulfillment rule sets for testing. These suggestions are prioritized based on projected impact and potential improvement to your Health Score such as a _12% mileage reduction_ or a _15% delivery time improvement_.

## Adding a new test

To start a test:

1. Navigate to the **Smart Order Routing** dashboard.
2. Click the plus (+) icon next to your current Fulfillment Health Score. This opens the **Suggested Rule Sets** window, where suggestions are sorted by default according to projected impact.
3. From the **Suggestion** column, choose a rule set and either:  
   - Click the **test name** to explore details and start testing.  
   - Click the **Apply to Test Slot** checkmark icon on the far right of the row to immediately begin testing.

### Apply to Test Slot

When you click the **Apply to Test Slot** checkmark icon:

1. The test begins automatically.
2. If the selected rule set hasn’t been tested in over a day, the **Restart Performance Cycle** window will appear.
3. Click **Continue** to proceed.
4. The test will now appear in your rules dashboard with the status **Calculating Score** (initial scoring isn’t immediately available).

### Selecting a test name

The scoring details of the suggestion are displayed on the **Smart Order Routing** dashboard.

1. Click **Test It**.
2. One of the following actions takes place:  
   - If all test slots are full, the **Select a test slot to fill** window is displayed and you must select the test you want to replace.
   - If an empty test slot is available, the leftmost slot is automatically populated with the selected test.
3. The test’s status changes from **Inactive** to **Testing** and the Fulfillment Health Score begins recalculating. Once testing completes, the **Score Breakdown**, **Score Comparison**, and **Rules** tabs are updated along with the projected improvement to your Fulfillment Health Score.
