I have created a Installhandler class for the custom setting object and I would like to test whether it works properly when the installer installs it? How can I accomplish this? Since this is the first time I am creating the package I would like to know the steps for achieving the same? As of now I have created a separate Org and passed the install handler class and its associated test class into it..
How can I verify whether the handler script is running properly and the records of custom settings are properly inserted into it? Any thoughts please. Thanks.
