integration testing your Pulumi code - anybody have a good system / language / pattern working for them?

examples

repo nightly at https://github.com/pulumi/examples/blob/master/misc/test/examples_test.go. This is something that anyone can use for their own projects if desired - though it is not the ideal solution here. We have a big investment planned in the near future on enabling integration testing for Pulumi projects within the source language (JS/TS/Python) using native test framework.
