bug: Setting _TESTING=1 environment variable causes ReferenceError to MOCK_LOG

Do I have the most recent component updates?

[X] I use the most recent available driver/plugin and server versions

Is the component officially supported by the Appium team?

[X] I have verified the component repository is present under the Appium organization in GitHub

Is there an existing issue for this?

[X] I have searched the existing issues

Current Behavior

Attempting to use appium-adb package with the _TESTING environment variable set to 1 causes a JavaScript error: ReferenceError: Cannot access 'MOCK_LOG' before initialization

If _TESTING=1 is left unset, the code works as expected.

Expected Behavior

The call to ADB.createADB() completes without error, and the _TESTING=1 environment variable omits the extra logging output.
