This is just a prototype to gather some feedback in our ongoing research
on integration testing of Terraform modules. The hope is that by having a
command integrated into Terraform itself it'll be easier for interested
module authors to give it a try, and also easier for us to iterate quickly
based on feedback without having to coordinate across multiple codebases.
Everything about this is subject to change even in future patch releases.
Since it's a CLI command rather than a configuration language feature it's
not using the language experiments mechanism, but generates a warning
similar to the one language experiments generate in order to be clear that
backward compatibility is not guaranteed.
As part of ongoing research into Terraform testing we'd like to use an
experimental feature to validate our current understanding that expressing
tests as part of the Terraform language, as opposed to in some other
language run alongside, is a good and viable way to write practical
module integration tests.
This initial experimental incarnation of that idea is implemented as a
provider, just because that's an easier extension point for research
purposes than a first-class language feature would be. Whether this would
ultimately emerge as a provider similar to this or as custom language
constructs will be a matter for future research, if this first
experiment confirms that tests written in the Terraform language are the
best direction to take.
The previous incarnation of this experiment was an externally-developed
provider apparentlymart/testing, listed on the Terraform Registry. That
helped with showing that there are some useful tests that we can write
in the Terraform language, but integrating such a provider into Terraform
will allow us to make use of it in the also-experimental "terraform test"
command, which will follow in subsequent commits, to see how this might
fit into a development workflow.
Changes:
```
* backend/s3: Support for AWS Single-Sign On (SSO) cached credentials
```
Updated via:
```
go get github.com/aws/aws-sdk-go@v1.37.0
go mod tidy
```
Please note that Terraform CLI will not initiate or perform the AWS SSO login flow. It is expected that you have already performed the SSO login flow using AWS CLI using the `aws sso login` command, or by some other mechanism before executing Terraform. More precisely, this credential handling must find a valid non-expired access token for the AWS SSO user portal URL in `~/.aws/sso/cache`. If a cached token is not found, is expired, or the file is malformed an error will be returned.
You can use configure AWS SSO credentials from the AWS shared configuration file by specifying the required keys in the profile:
```
sso_account_id
sso_region
sso_role_name
sso_start_url
```
For example, the following defines a profile "devsso" and specifies the AWS SSO parameters that defines the target account, role, sign-on portal, and the region where the user portal is located. Note: all SSO arguments must be provided, or an error will be returned.
```
[profile devsso]
sso_start_url = https:my-sso-portal.awsapps.com/start
sso_role_name = SSOReadOnlyRole
sso_region = us-east-1
sso_account_id = 123456789012
```

Here we propagate in the initialized terminal.Streams from package main,
and then onwards to backends running in CLI mode.
This also replaces our use of helper/wrappedstreams to determine whether
stdin is a terminal or a pipe. helper/wrappedstreams returns incorrect
file descriptors on Windows, causing StdinPiped to always return false on
that platform and thus causing one of the odd behaviors discussed in
Finally, this includes some wrappers around the ability to look up the
number of columns in the terminal in preparation for use elsewhere. These
wrappers deal with the fact that our unit tests typically won't populate
meta.Streams.
This is a helper package that creates a very thin abstraction over
terminal setup, with the main goal being to deal with all of the extra
setup we need to do in order to get a UTF-8-supporting virtual terminal
on a Windows system.
The upstream bug with opening a browser on Windows Subsystem for Linux
has been fixed, so this reverts our local patch for this. The approach
upstream adds fallback support for x-www-browser and www-browser if
xdg-open fails, and this fixes the problem on WSL.
This reverts commit 12e090ce48.
This is needed to make it possible to use the scram-sha-256
authentication method for the pg backend. It's not easy to write
unit-tests for this since it requires a specific configuration of the
PostgreSQL server, I did test it manually thought and everything seems
to work like it should.

Added an Off level to hclog, so we can individually disable logging at
various levels.
Added IndependentLevels so that sublogger levels are not linked to their
parents.
The main process is now handling what output to print, so it doesn't do
any good to try and run it through prefixedio, which is only adding
extra coordination to echo the same data.
helper/copy CopyDir was used heavily in tests. It differes from
internal/copydir in a few ways, the main one being that it creates the
dst directory while the internal version expected the dst to exist
(there are other differences, which is why I did not just switch tests
to using internal's CopyDir).
I moved the CopyDir func from helper/copy into command_test.go; I could
also have moved it into internal/copy and named it something like
CreateDirAndCopy so if that seems like a better option please let me
know.
helper/copy/CopyFile was used in a couple of spots so I moved it into
internal, at which point I thought it made more sense to rename the
package copy (instead of copydir).
There's also a `go mod tidy` included.
Update tests to match the fix in mitchellh/cli#71, which aligns MockUi
with BasicUi and allows newlines in user input.
We are not using the new ErrorWriter, added in mitchellh/cli#81, as it
does not appear to interact correctly with panicwrap. All error output
from CLI parsing will continue to appear on stdout, not stderr.
We've not been using HIL in the main codepaths since Terraform 0.12, but
some references to it (and some supporting functionality in Terraform)
stuck around due to interactions with types we'd kept around to support
legacy shims.
However, removing the configs.RawConfig field from
terraform.ResourceConfig disconnects that subtree of dependencies from
everything else, allowing us to remove it. This is safe because the only
remaining uses of terraform.ResourceConfig are shims from values that
were already evaluated using the HCL 2 API, and thus they never need
the "just in time" HIL evaluation that ResourceConfig.interpolateForce
used to do.
We also had some HIL references in configs/hcl2shim that were previously
in support of the "terraform 0.12upgrade" command, but the implementation
of that command is now removed.
There was one remaining reference to HIL in a now-unused function in the
helper/schema package, which I removed entirely here.
This then allows us to remove the HIL dependency entirely, and also to
clean up some remaining old remants of the legacy "config" package that
we'd recently moved into the "configs" package pending further pruning.
