Hi, I’m currently experimenting with the usage file and trying to use reserve instance cost instead of on demand. Do you maybe have an example of what it looks like for changes like changing xlarge instance to 2xlarge instance for reserved instance (all upfront)? I know the monthly cost is 0 since it charge by yearly so I would love to see how the UI looks like before switching to it. Many thanks

The unit tests have a lot of examples you can play around with.  If you look at <https://github.com/infracost/infracost/tree/master/internal/providers/terraform/aws/testdata/instance_test|this directory> you can see a `.tf` file, a `.usage.yml` file, and the output it produced saved in a `.golden`.  For example the all-front instance show up like <https://github.com/infracost/infracost/blob/master/internal/providers/terraform/aws/testdata/instance_test/instance_test.golden#L7|this>.
