# Testing flows

> The Test panel in Galantis Discount Flow — simulating carts and customers, reading the highlighted path, and a pre-publish checklist.

The Test panel is a dry-run environment built into the Rule Builder. It feeds a simulated cart and customer into your flow and shows exactly which blocks activate and which discounts would apply — using the same evaluation logic that runs on the storefront and at checkout. Because all three surfaces execute the flow identically, a result in the Test panel is the result your customer will get.

Open it with the **Test** button in the canvas toolbar. The **Test this flow** panel appears alongside the canvas, and every change you make to the simulated inputs re-evaluates the flow instantly.

## What you can simulate

The panel covers every input a condition can check:

| Input                                  | What it feeds                                                           |
| -------------------------------------- | ----------------------------------------------------------------------- |
| **Cart total**                         | The **Cart total** condition, spend thresholds in **Tiered discount**   |
| **Item quantity**                      | The **Item quantity** condition, **Volume pricing** tiers               |
| **Customer tags**                      | The **Customer tag** condition (comma-separated, e.g. `vip, wholesale`) |
| **Segment**                            | The **Customer segment** condition                                      |
| **Past order count**                   | The **Order count** condition                                           |
| **First order**                        | The **First order** condition                                           |
| **Discount code**                      | The **Discount code** condition                                         |
| **Country**                            | The **Customer country** condition                                      |
| **Date**                               | The **Day of week** condition                                           |
| **Cart contains selected products**    | The **Specific products** condition                                     |
| **Cart contains selected collections** | The **Specific collections** condition                                  |

## Reading the results

As you adjust inputs, two things update at once:

* **On the canvas** — the active path through the graph lights up, so you can see which conditions passed, which **Then** or **Otherwise** branches were taken, and which blocks the simulated cart never reached.
* **In the Result section** — every action that fires is listed with an **Applies** badge and a description of the discount. If nothing fires, the panel says so: "No discount applies for this cart and customer."

Watching the highlighted path is the fastest way to debug a flow. If a discount is not applying, follow the lit edges to the first condition that routed the flow to **Otherwise** — that is the check the simulated cart failed.

<Note>
  Testing is completely safe. The Test panel evaluates the flow in the builder only — it never publishes anything, never creates a discount, and never affects your live store or real customers.
</Note>

## Pre-publish test checklist

Run through these simulations before publishing any campaign:

<Steps>
  <Step title="Test the happy path">
    Set the inputs to a cart and customer that should clearly qualify. Confirm the intended action fires with an **Applies** badge and that the description matches the discount you meant to build.
  </Step>

  <Step title="Test a cart that should not qualify">
    Flip one input below the threshold — drop the **Cart total**, clear the **Customer tags**, or untick **Cart contains selected products**. Confirm the panel reports that no discount applies.
  </Step>

  <Step title="Probe the exact boundaries">
    Test values right at your thresholds — a cart total exactly equal to the amount, the precise quantity of a volume tier. This catches "is greater than" where you meant "is greater than or equal to".
  </Step>

  <Step title="Walk every Otherwise branch">
    If your flow branches, simulate inputs that send the cart down each **Otherwise** path and confirm each branch does what you expect — including doing nothing where nothing is intended.
  </Step>

  <Step title="Test customer-dependent conditions both ways">
    Conditions like **Customer tag**, **Customer segment**, **Order count**, and **First order** require a logged-in customer. Simulate both a qualifying customer and an empty guest-like profile so you know what anonymous shoppers get.
  </Step>

  <Step title="Confirm the flow is valid">
    Check the toolbar shows the **Valid** badge rather than an issue count. A flow with errors cannot be saved or published until every issue is resolved.
  </Step>
</Steps>

<Tip>
  If a flow uses a **Discount code** condition, type the exact code into the panel's **Discount code** field during testing — with the field empty, the condition fails and the whole campaign correctly reports no discount, which is easy to mistake for a broken flow.
</Tip>
