_TestConnection() function

[resuni]

I can't get the "_TestConnection()" function to work as described here: https://github.com/WHMCS/sample-provisioning-module/blob/master/modules/servers/provisioningmodule/provisioningmodule.php#L381

I return an array just like the example shows, but if I press the "Test Connection" button in the server settings, a loading wheel next to the button spins indefinitely. I know my code is executing fine, because I can use the "logModuleCall()" function to log expected values to the module debug log right before I return the array.

I also notice that "_TestConnection()" is not listed as a supported function in the documentation: https://developers.whmcs.com/provisioning-modules/supported-functions/

It seems like something about this function isn't documented right.

For anyone else that has this spinning wheel problem, I was able to fix it by switching from PHP 5.6 to PHP 7.2.

I'll close this issue, but I still think this function needs better documentation. For example, it looks like it's only possible to display a custom message when the test fails. Can a custom message be displayed when the test succeeds instead of just displaying "SUCCESS!"?
