AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a comprehensive set of patterns and best practices for authoring acceptance tests for Terraform providers built with the Plugin Framework. It covers the lifecycle of test execution, the structure of test cases and steps, and modern assertion techniques using ConfigStateChecks. It also includes guidance on handling import testing, ephemeral resources, and regression testing, ensuring consistent and maintainable test suites.

What it does

Defines test lifecycle stages including plan, apply, refresh, and destroy.
Provides patterns for modern ConfigStateChecks and plan assertions.
Demonstrates how to implement custom state checks for API verification.
Outlines strategies for testing ephemeral resources using the echo provider.
Details import testing workflows and state verification.
Offers templates for regression testing and scenario-based test steps.

When to use it

When writing new acceptance tests for a Terraform provider.
When refactoring legacy tests to use modern Plugin Framework testing patterns.
When debugging failing provider tests related to state or plan drift.
When implementing tests for ephemeral resources or complex import scenarios.

Advantages

Promotes type-safe assertions with aggregated error reporting.
Ensures consistent test structure across provider codebases.
Facilitates easier reproduction of bugs through regression test patterns.
Provides clear separation between test logic and provider configuration.

Usage examples

“How do I assert that a resource attribute matches a specific value in a test step?”: Use the ConfigStateChecks field with statecheck.ExpectKnownValue, specifying the resource address, the attribute path via tfjsonpath, and the expected value type.
“What is the recommended way to verify that a resource is destroyed after a test?”: Implement a TestCheckFunc that queries the API for the resource ID and returns an error if the resource still exists, then assign this to the CheckDestroy field in the TestCase.
“How can I test an ephemeral resource?”: Use the echoprovider package to capture ephemeral data into a managed resource's state, then perform standard ConfigStateChecks on that managed resource.
“How should I structure a regression test for a GitHub issue?”: Create a dedicated test function that reproduces the specific configuration triggering the bug, include a reference to the issue, and use ConfigStateChecks to verify the fix.

Provider Acceptance Test Patterns

Patterns for writing acceptance tests using terraform-plugin-testing with the Plugin Framework.

Test Lifecycle

The framework runs each TestStep through: plan → apply → refresh → final plan. If the final plan shows a diff, the test fails (unless ExpectNonEmptyPlan is set). After all steps, destroy runs followed by CheckDestroy. This means every test automatically verifies that configurations apply cleanly and produce no drift — no assertions needed for that.

Test Function Structure

func TestAccExample_basic(t *testing.T) {
    var widget example.Widget
    rName := acctest.RandStringFromCharSet(10, acctest.CharSetAlphaNum)
    resourceName := "example_widget.test"

    resource.ParallelTest(t, resource.TestCase{
        PreCheck:                 func() { testAccPreCheck(t) },
        ProtoV6ProviderFactories: testAccProtoV6ProviderFactories,
        CheckDestroy:             testAccCheckExampleDestroy,
        Steps: []resource.TestStep{
            {
                Config: testAccExampleConfig_basic(rName),
                ConfigStateChecks: []statecheck.StateCheck{
                    stateCheckExampleExists(resourceName, &widget),
                    statecheck.ExpectKnownValue(resourceName,
                        tfjsonpath.New("name"), knownvalue.StringExact(rName)),
                    statecheck.ExpectKnownValue(resourceName,
                        tfjsonpath.New("id"), knownvalue.NotNull()),
                },
            },
        },
    })
}

Use resource.ParallelTest by default. Use resource.Test only when tests share state or cannot run concurrently.

Provider Factory

// provider_test.go — Plugin Framework with Protocol 6 (use Protocol5 variant if needed)
var testAccProtoV6ProviderFactories = map[string]func() (tfprotov6.ProviderServer, error){
    "example": providerserver.NewProtocol6WithError(New("test")()),
}

TestCase Fields

Field	Purpose
`PreCheck`	`func()` — verify prerequisites (env vars, API access)
`ProtoV6ProviderFactories`	Plugin Framework provider factories
`CheckDestroy`	`TestCheckFunc` — verify resources destroyed after all steps
`Steps`	`[]TestStep` — sequential test operations
`TerraformVersionChecks`	`[]tfversion.TerraformVersionCheck` — gate by CLI version

TestStep Fields

Config Mode

Field	Purpose
`Config`	Inline HCL string to apply
`ConfigStateChecks`	`[]statecheck.StateCheck` — modern assertions (preferred)
`ConfigPlanChecks`	`resource.ConfigPlanChecks{PreApply: []plancheck.PlanCheck{...}}`
`ExpectError`	`*regexp.Regexp` — expect failure matching pattern
`ExpectNonEmptyPlan`	`bool` — expect non-empty plan after apply
`PlanOnly`	`bool` — plan without applying
`Destroy`	`bool` — run destroy step
`PreConfig`	`func()` — setup before step

Import Mode

Field	Purpose
`ImportState`	`true` to enable import mode
`ImportStateVerify`	Verify imported state matches prior state
`ImportStateVerifyIgnore`	`[]string` — attributes to skip during verify
`ImportStateKind`	`resource.ImportBlockWithID` — import block generation
`ResourceName`	Resource address to import
`ImportStateId`	Override the ID used for import

Check Functions

Modern: ConfigStateChecks (preferred)

Type-safe with aggregated error reporting. Compose built-in checks with custom statecheck.StateCheck implementations. See references/checks.md for full knownvalue types, tfjsonpath navigation, and comparers.

ConfigStateChecks: []statecheck.StateCheck{
    stateCheckExampleExists(resourceName, &widget),
    statecheck.ExpectKnownValue(resourceName,
        tfjsonpath.New("name"), knownvalue.StringExact("my-widget")),
    statecheck.ExpectKnownValue(resourceName,
        tfjsonpath.New("enabled"), knownvalue.Bool(true)),
    statecheck.ExpectKnownValue(resourceName,
        tfjsonpath.New("id"), knownvalue.NotNull()),
    statecheck.ExpectSensitiveValue(resourceName,
        tfjsonpath.New("api_key")),
},

Do not mix Check (legacy) and ConfigStateChecks in the same step.

Legacy: Check (for CheckDestroy and migration)

CheckDestroy on TestCase requires TestCheckFunc. The Check field on TestStep also accepts TestCheckFunc but prefer ConfigStateChecks for new tests.

Check: resource.ComposeAggregateTestCheckFunc(
    resource.TestCheckResourceAttr(name, "key", "expected"),
    resource.TestCheckResourceAttrSet(name, "id"),
    resource.TestCheckNoResourceAttr(name, "removed"),
    resource.TestMatchResourceAttr(name, "url", regexp.MustCompile(`^https://`)),
    resource.TestCheckResourceAttrPair(res1, "ref_id", res2, "id"),
),

ComposeAggregateTestCheckFunc reports all errors; ComposeTestCheckFunc fails fast on the first.

Config Helpers

Use numbered format verbs — %[1]q for quoted strings, %[1]s for raw:

func testAccExampleConfig_basic(rName string) string {
    return fmt.Sprintf(`
resource "example_widget" "test" {
  name = %[1]q
}
`, rName)
}

func testAccExampleConfig_full(rName, description string) string {
    return fmt.Sprintf(`
resource "example_widget" "test" {
  name        = %[1]q
  description = %[2]q
  enabled     = true
}
`, rName, description)
}

Scenario Patterns

Basic + Update (combine in one test — updates are supersets of basic)

Steps: []resource.TestStep{
    {
        Config: testAccExampleConfig_basic(rName),
        ConfigStateChecks: []statecheck.StateCheck{
            stateCheckExampleExists(resourceName, &widget),
            statecheck.ExpectKnownValue(resourceName,
                tfjsonpath.New("name"), knownvalue.StringExact(rName)),
        },
    },
    {
        Config: testAccExampleConfig_full(rName, "updated"),
        ConfigStateChecks: []statecheck.StateCheck{
            stateCheckExampleExists(resourceName, &widget),
            statecheck.ExpectKnownValue(resourceName,
                tfjsonpath.New("description"), knownvalue.StringExact("updated")),
        },
    },
},

Import

After a config step, verify import produces identical state. Use ImportStateKind for import block generation:

{
    ResourceName:      resourceName,
    ImportState:       true,
    ImportStateVerify: true,
    ImportStateKind:   resource.ImportBlockWithID,
},

Disappears (resource deleted externally)

{
    Config: testAccExampleConfig_basic(rName),
    ConfigStateChecks: []statecheck.StateCheck{
        stateCheckExampleExists(resourceName, &widget),
        stateCheckExampleDisappears(resourceName),
    },
    ExpectNonEmptyPlan: true,
},

Validation (expect error)

{
    Config:      testAccExampleConfig_invalidName(""),
    ExpectError: regexp.MustCompile(`name must not be empty`),
},

Regression (two-commit workflow)

A proper bug fix uses at least two commits: first commit the regression test (which fails, confirming the bug), then commit the fix (test passes). This lets reviewers independently verify the test reproduces the issue by checking out the first commit, then advancing to the fix.

Name and document regression tests to identify the issue they fix. Include a link to the original bug report when possible.

// TestAccExample_regressionGH1234 verifies fix for https://github.com/org/repo/issues/1234
func TestAccExample_regressionGH1234(t *testing.T) {
    rName := acctest.RandStringFromCharSet(10, acctest.CharSetAlphaNum)
    resourceName := "example_widget.test"

    resource.ParallelTest(t, resource.TestCase{
        PreCheck:                 func() { testAccPreCheck(t) },
        ProtoV6ProviderFactories: testAccProtoV6ProviderFactories,
        CheckDestroy:             testAccCheckExampleDestroy,
        Steps: []resource.TestStep{
            {
                // Reproduce the issue: this config triggered the bug
                Config: testAccExampleConfig_regressionGH1234(rName),
                ConfigStateChecks: []statecheck.StateCheck{
                    stateCheckExampleExists(resourceName, nil),
                    statecheck.ExpectKnownValue(resourceName,
                        tfjsonpath.New("computed_field"), knownvalue.NotNull()),
                },
            },
        },
    })
}

Helper Functions

Custom StateCheck: Exists

Implement statecheck.StateCheck for API existence verification. Separate the exists check into its own function for reuse across steps — the source recommends this as a design principle:

type exampleExistsCheck struct {
    resourceAddress string
    widget          *example.Widget
}

func (e exampleExistsCheck) CheckState(ctx context.Context, req statecheck.CheckStateRequest, resp *statecheck.CheckStateResponse) {
    r, err := stateResourceAtAddress(req.State, e.resourceAddress)
    if err != nil {
        resp.Error = err
        return
    }

    id, ok := r.AttributeValues["id"].(string)
    if !ok {
        resp.Error = fmt.Errorf("no id found for %s", e.resourceAddress)
        return
    }

    conn := testAccAPIClient()
    widget, err := conn.GetWidget(id)
    if err != nil {
        resp.Error = fmt.Errorf("%s not found via API: %w", e.resourceAddress, err)
        return
    }

    if e.widget != nil {
        *e.widget = *widget
    }
}

func stateCheckExampleExists(name string, widget *example.Widget) statecheck.StateCheck {
    return exampleExistsCheck{resourceAddress: name, widget: widget}
}

Custom StateCheck: Disappears

Delete a resource via API to simulate external deletion:

type exampleDisappearsCheck struct {
    resourceAddress string
}

func (e exampleDisappearsCheck) CheckState(ctx context.Context, req statecheck.CheckStateRequest, resp *statecheck.CheckStateResponse) {
    r, err := stateResourceAtAddress(req.State, e.resourceAddress)
    if err != nil {
        resp.Error = err
        return
    }

    id := r.AttributeValues["id"].(string)
    conn := testAccAPIClient()
    resp.Error = conn.DeleteWidget(id)
}

func stateCheckExampleDisappears(name string) statecheck.StateCheck {
    return exampleDisappearsCheck{resourceAddress: name}
}

State Resource Lookup (shared utility)

func stateResourceAtAddress(state *tfjson.State, address string) (*tfjson.StateResource, error) {
    if state == nil || state.Values == nil || state.Values.RootModule == nil {
        return nil, fmt.Errorf("no state available")
    }
    for _, r := range state.Values.RootModule.Resources {
        if r.Address == address {
            return r, nil
        }
    }
    return nil, fmt.Errorf("not found in state: %s", address)
}

Destroy Check (TestCheckFunc — required by CheckDestroy)

func testAccCheckExampleDestroy(s *terraform.State) error {
    conn := testAccAPIClient()
    for _, rs := range s.RootModule().Resources {
        if rs.Type != "example_widget" {
            continue
        }
        _, err := conn.GetWidget(rs.Primary.ID)
        if err == nil {
            return fmt.Errorf("widget %s still exists", rs.Primary.ID)
        }
        if !isNotFoundError(err) {
            return err
        }
    }
    return nil
}

PreCheck

func testAccPreCheck(t *testing.T) {
    t.Helper()
    if os.Getenv("EXAMPLE_API_KEY") == "" {
        t.Fatal("EXAMPLE_API_KEY must be set for acceptance tests")
    }
}

in Section 2.1.

3. Responsibilities
-------------------

3.1. Distribution of Source Form

All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.

3.2. Distribution of Executable Form

If You distribute Covered Software in Executable Form then:

(a) such Covered Software must also be made available in Source Code
    Form, as described in Section 3.1, and You must inform recipients of
    the Executable Form how they can obtain a copy of such Source Code
    Form by reasonable means in a timely manner, at a charge no more
    than the cost of distribution to the recipient; and

(b) You may distribute such Executable Form under the terms of this
    License, or sublicense it under different terms, provided that the
    license for the Executable Form does not attempt to limit or alter
    the recipients' rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).

3.4. Notices

You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.

4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------

If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.

5. Termination
--------------

5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.

*  authorized under this License except under this disclaimer.         *

*  shall have been informed of the possibility of such damages. This   *
*  limitation of liability shall not apply to liability for death or   *
*  personal injury resulting from such party's negligence to the       *
*  extent applicable law prohibits such limitation. Some               *
*  jurisdictions do not allow the exclusion or limitation of           *
*  incidental or consequential damages, so this exclusion and          *
