terrassert

Terraform provider for making assertions on the output of modules

This is a terraform provider for making assertions about outputs from modules and resources.

Motivation

The ultimate goal is to have mock terraform providers so that HCL terraform configuration can be unit tested. For example, something like this:

provider "mock_aws" {
  region     = "us-east-1"
}

resource "mock_aws_when" "kinesis" {
    resource = "aws_kinesis_stream"
    then_return = {
        arns = ["firstArn", "secondArn]
        id = ["firstId", "secondId"]
    }
}

locals {
  foo = 12
  bar = "xyz"
}

resource "aws_kinesis_stream" "test_stream" {
  name             = "${local.bar}"
  shard_count      = "${local.foo}"
  retention_period = 48
}

data "terrassert_equals" "kinesis_name" {
    actual = "${aws_kinesis_stream.test_stream.name}"
    expected = "xyz"
    message = "Name should be xyz"
}

data "terrassert_gt" "kinesis_counte" {
    actual = "${aws_kinesis_stream.test_stream.shard_count}"
    gt = 1
    message = "Shard count shoudl be greater than 1"
}

This provider will just provide the 2 last data providers. I have no idea (yet) if the mock_aws provider will work or not.
