v1.0.0

Terratest 1.0.0 is the first stable release of the project. From this release forward, Terratest follows semantic versioning: breaking changes are restricted to major releases, and renamed or replaced symbols stay around as deprecated aliases in the v1 line. See the v1.0 announcement post for the narrative; the notes below cover what shipped.

✨ Highlights

• Context plumbing throughout. Every cloud-API helper now takes an explicit context.Context as its second argument. FooContext (fail-fast) and FooContextE (returns the error) are the canonical entrypoints; the bare Foo and FooE forms remain as deprecated aliases.
• Mockable SDK clients. Most Azure and GCP helpers that previously hid SDK client construction now ship with a WithClient sibling that accepts an injected client. Drive Terratest against Azure's azfake server or a GCP test double for fast unit tests with zero credentials.
• Modern, supported underlying SDKs. modules/azure migrated off Microsoft's archived "track 1" SDK onto sdk/resourcemanager; AWS S3 helpers moved off the deprecated s3/manager to s3/transfermanager.
• Terragrunt v1.0 feature parity. The terragrunt module fully supports Terragrunt v1.0's CLI redesign with new wrappers and single-unit variants. Terragrunt-specific code is separated from modules/terraform into its own module.
• Reliability fixes. EC2 list calls paginate, OPA policy downloads deduplicate, several panics on empty SDK responses are now errors.

⚠️ Breaking Changes

Azure SDK migration

modules/azure moved off the archived "track 1" Azure SDK onto the actively maintained sdk/resourcemanager. Users who import the underlying SDK directly need to update import paths, move field access under .Properties, and replace iterators with pagers. The release also dropped 8 deprecated Get*ClientE getters in favor of Create*ClientE, renamed 4 CreateNew*Client* factories (with deprecated aliases), fixed the NsgRuleSummary.SourceAdresssPrefixes typo, and changed GetVirtualMachineImage{,E} to return *VMImage. See the Azure migration guide for full mechanics.

AWS S3 uploader

The four NewS3Uploader* helpers now return *transfermanager.Client instead of *manager.Uploader. The call shape moves from uploader.Upload(ctx, &s3.PutObjectInput{...}) to client.UploadObject(ctx, &transfermanager.UploadObjectInput{...}). Types live under github.com/aws/aws-sdk-go-v2/feature/s3/transfermanager.

GCP Pub/Sub

modules/gcp/pubsub.go moved from cloud.google.com/go/pubsub v1 to v2. Wrapper shapes are unchanged, but callers driving the underlying client directly switch from client.Topic("name") / client.Subscription("name") handles to TopicAdminClient / SubscriptionAdminClient calls that take fully qualified resource names.

Terragrunt module split

Terragrunt-specific helpers were removed from modules/terraform/ and modules/test-structure/ in favor of the dedicated modules/terragrunt/ package: TgApplyAll, TgDestroyAll, TgPlanAllExitCode, ValidateInputs, InitAndValidateInputs, AssertTgPlanAllExitCode, TgInvalidBinary, TerragruntDefaultPath, ExtraArgs.ValidateInputs, NewTerragruntValidationOptions, and the TG constant. Terragrunt stack output keys were also renamed. See the terragrunt module migration table.

Kubernetes kubeconfig handling

GetKubernetesClientFromOptionsContextE now logs the kubeconfig load error before falling back to in-cluster authentication; previously the fallback was silent. A new KubectlOptions.InClusterAuth = true opt-in skips kubeconfig loading entirely for callers who want fully explicit auth.

testing.TestingT adoption

Helper signatures consistently take testing.TestingT (an interface) instead of the concrete *testing.T. Calls from *testing.T are unaffected; callers that wrap or substitute the test handle may need updates.

✨ New Features

WithClient injection helpers across Azure and GCP

Most Azure and GCP helpers now ship with a *WithClient sibling that accepts a pre-built SDK client, enabling unit testing against Azure's azfake server, GCP test doubles, and similar fakes without standing up real cloud resources or providing credentials.

Terragrunt v1.0 feature parity

All terraform-passthrough commands use terragrunt run -- <command> and multi-unit functions use terragrunt run --all -- <command>. Generic Run / RunE provide an escape hatch. New command wrappers: Render, RenderJSON, Graph, HclValidate, OutputAllJson, plus single-unit variants for Init, Plan, Apply, Destroy, Validate, and OutputJson.

GCP Pub/Sub helpers

AssertTopicExists and AssertSubscriptionExists added to modules/gcp/pubsub.go. Thanks to @Amit2465 for the contribution.

🔧 Code Quality & API Cleanup

• Godoc and // Deprecated: annotations. A v1 documentation pass closed godoc gaps so the API surface renders cleanly on pkg.go.dev. Every renamed or replaced symbol carries a machine-readable // Deprecated: line so go vet, staticcheck, and IDE LSPs surface upgrade guidance automatically.
• Strict golangci-lint v2 wired into pre-commit and CI across the project.
• interface{} → any sweep across the codebase.
• collections generics: functions are now generic; ListContains is deprecated in favor of slices.Contains.

🐛 Bug Fixes

• EC2 list pagination: DescribeInstances and DescribeTags now paginate; previously capped silently at 1,000 results.
• Concurrent OPA download deduplication: modules/opa/download_policy.go uses singleflight so concurrent calls for the same rulePath share a single download.
• Empty-response panics → errors: RDS, IAM, OCI list calls, and several Azure SDK-response paths return typed errors on empty responses where they previously panicked on unchecked slice access.
• ACM pagination: ACM list calls now paginate.
• OCI nil-safety: ListVcns and related calls loop on OpcNextPage; image sort handles nil timestamps; nil-pointer guards added across the package.
• SSH file-handle leak: SCPDirFromContextE closes file handles on each download.
• OPA cache concurrency race: cache initialization is now race-free under concurrent test runs.
• Azure NSG field name typo: NsgRuleSummary.SourceAdresssPrefixes renamed to SourceAddressPrefixes.

📦 Dependency Updates

• AWS SDK v2 bumped across every service used by Terratest; s3/manager (deprecated) replaced with s3/transfermanager.
• GCP SDKs current: cloud.google.com/go/storage 1.62, cloud.google.com/go/pubsub/v2 2.4, google.golang.org/api 0.276.
• Azure migrated off azure-sdk-for-go v51 onto the actively maintained sdk/resourcemanager modules (compute, network, storage, keyvault, sql, servicebus, frontdoor, monitor, recoveryservices, and others).
• mitchellh/go-homedir (archived) removed as a direct dependency in favor of os.UserHomeDir; denisenkom/go-mssqldb swapped for the Microsoft-maintained fork.
• google.golang.org/grpc 1.80, github.com/docker/cli 29.x, go.opentelemetry.io/otel/sdk 1.43, github.com/jackc/pgx/v5 5.9.
• OpenTofu pin updated to 1.11.6; Terragrunt baseline bumped to v1.0.2.

📖 Documentation Updates

• v1 migration guide covering breaking changes by service, with a dedicated Azure migration guide for the SDK move.
• Version pinning guide.
• README refreshed with stability and versioning policy; SECURITY.md added.

⚙️ Process Updates

• All CI moved from CircleCI to GitHub Actions.
• Multi-arch (linux / darwin / windows × amd64 / arm64 / 386) build-and-release workflow with SHA256SUMS.
• go-mod-tidy-check workflow added.

Full Changelog: v0.56.0...v1.0.0

v0.56.0

✨ New Features

CreateJobFromCronJob and CreateJobFromCronJobE added.

The CreateJobFromCronJob and CreateJobFromCronJobE functions support creating Kubernetes cron jobs in a given namespace. This mirrors the behavior of the kubectl create job ... --from=cronjob/... command and provides a native way to trigger and test CronJob configurations within Terratest.

Special thanks to @Steffas for contributing this feature.

🐛 Bug Fixes

Preserve existing instance metadata in SetMetadata

Updates the newMetadata function to properly copy existing metadata items before applying new key-value pairs. This resolves an issue introduced in v0.55.0 where functions like SetMetadata and AddSshKey were accidentally overwriting all existing instance metadata instead of merging the new values.

Plan output parsing for Terraform 1.14+ fixed

Removes the trailing period requirement from the planWithChangesRegexp regular expression used by GetResourceCount. This resolves parsing failures caused by Terraform 1.14's new Actions feature, which appends additional text (e.g., . Actions: N to invoke.) to the standard plan summary line.

Update CronJob to use the batch/v1 API

Updates the CronJob implementation under the hood to use the stable batch/v1 API instead of batch/v1beta1. This restores compatibility with modern Kubernetes clusters, as the older v1beta1 API was completely removed in Kubernetes 1.25.

📖 Documentation Updates

Homepage examples for Terragrunt updated

Examples relevant to Terragrunt have been fixed in the https://terragrunt.gruntwork.io site.
