# Test a decision table in Workflow Studio

Test your decision table in Workflow Studio before publishing to verify the rules provide the desired outcome for a given set of input data.

## Before you begin

You can only test saved decision tables. Create a table with at least one input and result, save it, and then test it. Alternatively, test an existing saved table.

Role required: admin, decision\_table\_admin, decision\_table\_reader, Change manager, or delegated developer

**Note:** Test decision table inputs within the specified maximum input limits. For example, if the limit is 40 characters, confirm that inputs do not exceed this length to avoid incorrect results.

## Procedure

1.  Navigate to **All** > **Process Automation** > **Workflow Studio**.

2.  On the homepage, select **Decision tables**.

3.  Select a decision table.

4.  Select **Test**.

5.  If the table has draft authoring enabled and it has already been published, select whether to test the draft or published version from the **What to test** list.

6.  From the **How to execute** list, select whether to return only the first matching decision or all matching decisions.

7.  Enter input data to test.

8.  Select **Test**.


## Result

The results display, showing either no results or the decisions where your input data matches the conditions. Run additional tests by changing the test parameters and selecting **Test** again.
