-In the above example, Terraform uses the supplied value for `arn` attributes in S3 buckets instead of generating a random string. Computed attributes not provided an explicit default will simply fall back to the generic data generation rules. You can also use the `override_during` attribute in the `mock_resource` and `mock_data` blocks to specify when Terraform should generate the values for an individual resource. If you do not not specify the `override_during` attribute, Terraform generates the values using the rules inherited from the `mock_provider` block. If specified, the local value overrides any value specified in the `mock_provider` block.

 You can also share mock provider data between tests by writing dedicated mock data files and using the `source` attribute in the `mock_provider` block. Mock data files have `.tfmock.hcl` or `.tfmock.json` extension, and can contain `mock_resource` and `mock_data` blocks as if they were defined in the `mock_provider` block directly.
