EXPERIMENTS:

Experiments are only enabled in alpha releases of Terraform CLI. The following features are not yet available in stable releases.

The experimental "deferred actions" feature, enabled by passing the -allow-deferral option to terraform plan, permits count and for_each arguments in module, resource, and data blocks to have unknown values and allows providers to react more flexibly to unknown values.
terraform test cleanup: The experimental test cleanup command. In experimental builds of Terraform, a manifest file and state files for each failed cleanup operation during test operations are saved within the .terraform local directory. The test cleanup command will attempt to clean up the local state files left behind automatically, without requiring manual intervention.
terraform test: backend blocks and skip_cleanup attributes:
- Test authors can now specify backend blocks within run blocks in Terraform Test files. Run blocks with backend blocks will load state from the specified backend instead of starting from empty state on every execution. This allows test authors to keep long-running test infrastructure alive between test operations, saving time during regular test operations.
- Test authors can now specify skip_cleanup attributes within test files and within run blocks. The skip_cleanup attribute tells terraform test not to clean up state files produced by run blocks with this attribute set to true. The state files for affected run blocks will be written to disk within the .terraform directory, where they can then be cleaned up manually using the also experimental terraform test cleanup command.
