# Workflow runs
> What a Workflow run is, how to start one, and how to review its results
A Workflow run is a single execution of a Workflow. It starts when an input is submitted and ends when the final output is generated. While a Workflow provides the reusable structure (its steps, nodes, and logic), each run represents a unique instance of that Workflow in action.
Workflow runs let you automate analysis, generate insights, and execute connected tasks consistently and repeatedly, without needing to reconfigure the Workflow each time.
## Test Workflow runs
Test runs let you track the inputs, outputs, and variables of each step more closely. From the Workflow Builder, you can view the results of a test run, including:
* The steps executed.
* The variables produced at each stage.
* The final output returned by the Workflow.
This makes it easy to troubleshoot, refine prompts, or verify that your Workflow logic behaves as expected.
Trigger a test run by clicking **Run Test** in the upper right-hand corner of the Workflow Builder.
You can run tests for both published and draft Workflows. To run a test from a published Workflow, go to the Workflow page, select **Edit** on the top right of the page, and test the Workflow in the Workflow Builder.
## Trigger a Workflow run
A Workflow run begins when you:
* Select **Run** for the desired Workflow
* Provide input
Each run processes the values you provide, transforms them through each step, and produces a final output.
## How Workflow runs work
During a run, the Workflow's steps execute in a linear order:
1. **Inputs are captured**. The Workflow records the values you provide and stores them as variables.
2. **Steps execute sequentially**. Each node performs its action, such as running Answer Engine Insights, prompting a model, or calling an external tool.
3. **Variables pass between steps**. Outputs from each step become new variables that can be reused or combined later in the run.
4. **A final output is generated**. The run ends at the End step, producing a result or simply marking the run’s completion.
Because each run is independent, the same Workflow can produce different results based on the inputs you provide or data retrieved during the process.
## View run results
Workflow outputs from the latest run appear on the Workflow's page. Select **Past runs** to see the outputs for all runs of the Worklow.
