This test presents itself in an awkward manner as part of the AWS test
suite rather than the core test suite - this is because you cannot use
real providers in context tests because of circular references, and
simplistic test providers in that package do not demonstrate the issue.
In the interests of getting this fix in quickly and still having
regression coverage for it, it was agreed to include the change here
instead.
Running the test TestAccAWSVPC_coreMismatchedDiffs without the changes
in d95ab75 applied leads to the following output:
```

Applying the changes in d95ab75 (pull request GH-4965) yields the
following result when running the test:

The test has a rather misleading name ("AWS") such that it is actually run as
part of the nightly acceptance testing. The VPC resource is quick and free to
create, hence the selection.
The AWS free tier allows up to 750 hours on t2.micro
instance types. It's better to use cheaper instances
in case the resources are not cleaned up if a tests
is canceled or crashes.
There can only be a single health_check configuration per load balancer
so choosing to use a list over a set is only relevant when comparing
changes during a plan. A list makes it much easier to compare updates
since the index is stable (0 vs. computed hash).
Removes overspecified config that is unrelated to testing the auto scaling
group's autogenerated name. The test is only concerned with checking that
the auto scaling group was created successfully with an autogenerated name
matching a specific pattern.
Removes overspecified config that is unrelated to the auto scaling
group's availability zone and VPC identifier acceptance tests. The
created auto scaling groups do not need to spin up any hosts since
the acceptance tests are only concerned with checking the existence
of the associated availability zones and VPC identifiers.
Fixes a diff calculation error when only a VPC zone
identifiers is provided. In this case the associated
availability zones are computed from the subnets per
the AWS documentation.
This is a follow up on #4892 with tests that demonstrate creating a record and a zone, then destroying said record, and confirming that a new plan is generated, using the ExpectNonEmptyPlan flag
This simulates the bug reported in #4641 by mimicking the state file that one would have if they created a record with Terraform v0.6.6, which is to say a weight = 0 for a default value.
When upgrading, there would be an expected plan change to get that to -1. To mimic the statefile we apply the record and then in a follow up step change the attributes directly. We then try to delete the record.
I tested this by grabbing the source of aws_resource_route53.go from Terraform v0.6.9 and running the included test, which fails. The test will pass with #4892 , because we no longer reconstruct what the record should be based on the state (instead finding via the API and elimination/matching)
