# Auto Testing using UI
## **Add test data to the Policy**
Tests can be added to the Policy, when such a policy gets published then the added tests get embedded into the policy file.
Such tests are imported/exported together with their respective policies.
{% hint style="info" %}
**Note:** Tests can be run only when the policy is in the dry-run or demo status.
{% endhint %}
### 1. Adding Tests
Tests can be added to the policy via the corresponding menu option as shown on the screenshots below:
### 2. Running Tests
To launch a test navigate to the tests list using the ‘Test details’ menu option\\
\
Select the desired test in the grid and press ***Run (or Re-Run)***
{% hint style="info" %}
**Note:** There could be only one active (running) test per policy, multiple policies can be running tests at the same time.
{% endhint %}
### 3. View Test Results
Test results can be viewed in the test window
There are potential outcomes of running policy tests
1. **Stopped** – test was stopped by the user
2. **Success** – test was successfully executed and the results are fully matching those originally captured
3. **Failure (1)** – an error has occurred during the run of the test, the execution of the test was not completed
4. **Failure (2)** – test was executed, however test results (i.e. the produced artifacts) differ from those originally captured
Detailed comparison of the execution results (documents) can be performed by clicking on the ‘Show more details’ button.
### 4. Removing Tests
Tests which are not being run can be deleted.
### 5. Access from the grid
Tests can be managed and run from the Manage Policies grid.
This view allows to:
* Add a test to the policies if it does not yet have any tests
* Run the most recently added test
* Re-run the most recently run test
* Monitor the status of the test being run
## 2. Demo Mode
To simplify the UI of policy testing (useful for novice users) a new ‘**Demo**’ mode of policy import has been introduced. In this mode all policy processing is ‘read-only’, policy editing is not possible, and no communication with external systems such as Hedera network and/or IPFS is performed. Policy execution in the **Demo** mode is similar to **dry-run**.
To use demo mode the corresponding option should be selected on the policy import dialogue.
