To configure the default **Apex Test Class** for your Salesforce org, follow the steps below:

2. Hover your mouse over the **`Admin`** tab and click on the option: **`SF Org Mgmt`**.
3. Select your **`Salesforce Org`** from the list and go to the **`Salesforce Org - Default Apex Test Class Configuration`** section. While deploying through ARM, this works in sync with the **Run Test** based on the **Changes Test** level option. If ARM cannot find dependent test classes, these default classes will run as Specified Tests.

* Edit: You can add or delete Apex Class/Trigger for the Apex Test Class.
* Checkbox: This for selecting the Apex Test Class as part of the Default Apex Test Class, and you can click on save.
* Clear: This will clear your Default Apex Test Class Configuration for your Salesforce Org.
4. Different options to choose from:
**`a. Fetch Current Set:`** This option fetches Apex and Test classes dependency. From the list fetched, select the required Apex Test Class that you would like to configure and run into the Destination Org.
**`b. Auto-populate:`** This option will run all local tests and get the complete dependency map.
