# Test the Application

Before you deploy the application to the remote console, you can [test the application on a local server](https://docs.catalyst.zoho.com/en/cli/v1/serve-resources/introduction) and check if everything works fine using the Catalyst CLI.

To serve the Catalyst project locally, execute the following command from your project directory: 

```sh
 catalyst serve
```

The Lead Manager application will now be served at default port 3000\. The local endpoint URLs of
the components are displayed.

> **Note:** Every time you access the homepage or any of the sub-pages of
your client, or the function, the CLI will display a live log of the URL accessed, along with the
HTTP request method.

You can now open the application in a browser using the local URL of the client displayed in the CLI.

You will initially be redirected to the login page. If you configure a sign-up action on your own, you can sign up first, then log in to the application. Otherwise, you can log in using the Zoho sign-in icon.

You will be redirected to the permissions page. Accept the permissions requested by the app to access your Zoho account details.

![catalyst_leadmanager_test_2](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/lead-manager-zoho-signin.webp) 

You will then be redirected back to the application. Click the **Zoho CRM icon** in this page to connect to Zoho CRM.

![catalyst_leadmanager_test_3](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_3.webp) 

You must now **choose the CRM account** that you wish to connect with the Lead Manager app, then click **Submit**. All your existing developer, sandbox, and production accounts will be listed.

Click **Accept** to allow the Lead Manager app to access your Zoho CRM modules.

![catalyst_leadmanager_test_4](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/crm-connection-zoho-api.webp) 

You will be redirected back to the application. You can now create and manage leads in your configured Zoho CRM account, directly from this application.

To add a lead, enter the details of the lead in the _Add a Lead_ section and click **Add Lead**.

![catalyst_leadmanager_test_6](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_6.webp) 

A confirmation pop-up will display the status every time you add, edit, or delete a lead.

![catalyst_leadmanager_test_7](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_7.webp) 

You can click the **Manage Leads** tab to view all your leads from the Leads module. You can edit or delete any of them by clicking their respective icons in the table.

![catalyst_leadmanager_test_8](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_8.webp) 

You can update a lead's information, then click **Edit**.

![catalyst_leadmanager_test_9](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_9.webp) 

If you click the delete icon, you must confirm the action in the confirmation pop-up.

![catalyst_leadmanager_test_10](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_10.webp) 

You can also check the Refresh Token and `userID` values populated in the Data Store from your Catalyst console. Navigate to the **Data View** section of the _Token_ table to view the record that was added.

![catalyst_leadmanager_test_11](https://catalyst-docs-development.zohostratus.in/images/tutorials/leadmanager/catalyst_leadmanager_test_11.webp) 

If you delete this entry, you will have to authenticate your credentials in the client application and establish a connection to your CRM account again.

You can log out of the application by clicking **Logout**.

If this setup is working correctly, we can deploy the application to production.

You can quit the `serve` session in your terminal by executing the command to kill a running process, based on your OS.
