Terratest -如何在函数之间传递Terraform输出

Question

我试着使用'test_structure.SaveTerraformOptions‘，但它并没有节省资源I。例如，我运行两个模块-模块1创建网络和子网，模块2需要模块的1个子网ids。我怎样才能在他们之间传递这个信息？

当我在同一个“test_structure.RunTestStage”中运行两个函数时，我可以将资源id从一个函数传递到另一个函数，但它不会测试第一个函数，也不会在最后销毁。

我将编写一个助手函数，它将只加载所有内容，其他函数将进行测试。也许这个能帮上忙。

然而，这方面的最佳做法是什么？

这是我的密码：

package test

import (
    "testing"

    //"github.com/gruntwork-io/terratest/modules/random"

    "github.com/gruntwork-io/terratest/modules/azure"
    "github.com/gruntwork-io/terratest/modules/terraform"
    test_structure "github.com/gruntwork-io/terratest/modules/test-structure"
    "github.com/stretchr/testify/assert"
)

// An example of how to test the simple Terraform module in examples/terraform-basic-example using Terratest.

func TestRunAll(t *testing.T) {
    t.Parallel()

    environmentName := "dev"
    projectName := "toha"
    rgName := environmentName + "-" + projectName + "-rg"
    subscriptionID := "96b72f1a-1bdc-4fc7-b971-05e7cea7d850"

    rg_net := test_structure.CopyTerraformFolderToTemp(t, "../", "001_networking")

    test_structure.RunTestStage(t, "test_azure_resource_group", func() {
        terraformOptions := testAzureResourceGroup(t, rgName, subscriptionID)
        test_structure.SaveTerraformOptions(t, rg_net, terraformOptions)
        
        testTerraformAzureFunctionApp(t, rgName, terraformOptions)
        terraform.Destroy(t, terraformOptions)
    })
}

func testAzureResourceGroup(t *testing.T, rgName string, subscriptionID string) *terraform.Options {

    //uniquePostfix := strings.ToLower(random.UniqueId())
    terraformOptions := terraform.WithDefaultRetryableErrors(t, &terraform.Options{

        TerraformDir: "../001_networking",

        Vars: map[string]interface{}{
            "rg_name": rgName,
        },

        VarFiles: []string{"../../environments/dev/vars.tfvars"},

        // Disable colors in Terraform commands so its easier to parse stdout/stderr
        NoColor: true,
    })

    terraform.InitAndApply(t, terraformOptions)
    rg_name_out := terraform.Output(t, terraformOptions, "rg-name")

    assert.Equal(t, rgName, rg_name_out)

    return terraformOptions
}

func testTerraformAzureFunctionApp(t *testing.T, rgName string, netOpts *terraform.Options) {

    azurePortalIPRange := []string{"61.100.129.0/24"}

    subnet_1 := terraform.Output(t, netOpts, "azurerm_subnet_1")
    subnet_2 := terraform.Output(t, netOpts, "azurerm_subnet_2")

    terraformOptions := &terraform.Options{
        TerraformDir: "../002_function_app",

        Vars: map[string]interface{}{
            "subnet_id_1":           subnet_1,
            "subnet_id_2":           subnet_2,
            "rg_name":               rgName,
            "azure_portal_ip_range": azurePortalIPRange,
            "cosmos_db_endpoint":    "test",
            "cosmos_db_password":    "test",
        },

        VarFiles: []string{"../../environments/dev/vars.tfvars"},
    }

    defer terraform.Destroy(t, terraformOptions)
    terraform.InitAndApply(t, terraformOptions)

    resourceGroupName := terraform.Output(t, terraformOptions, "resource_group_name")
    appName := terraform.Output(t, terraformOptions, "function_app_name")

    appId := terraform.Output(t, terraformOptions, "function_app_id")
    appDefaultHostName := terraform.Output(t, terraformOptions, "default_hostname")
    appKind := terraform.Output(t, terraformOptions, "function_app_kind")

    // website::tag::4:: Assert
    assert.True(t, azure.AppExists(t, appName, resourceGroupName, ""))
    site := azure.GetAppService(t, appName, resourceGroupName, "")

    assert.Equal(t, appId, *site.ID)
    assert.Equal(t, appDefaultHostName, *site.DefaultHostName)
    assert.Equal(t, appKind, *site.Kind)

    assert.NotEmpty(t, *site.OutboundIPAddresses)
    assert.Equal(t, "Running", *site.State)
}

我认为使用test_structure的最佳方法是按阶段分离(https://pkg.go.dev/github.com/gruntwork-io/terratest/modules/test-structure#RunTestStage)：

1. 配置terratest，将特定配置的选项保存到terraform -> SETUP

test_structure.RunTestStage(t，"SETUP"，func() { terraformOption := &terraform.Options{ TerraformDir："your/path/here"，} test_structure.SaveTerraformOptions(t，目录，terraformOption) terraform.InitAndApply(t，terraformOption) })

1. 在测试结束时摧毁你的潜艇->拆卸

延迟test_structure.RunTestStage(t，"TEARDOWN"，func() { terraformOptions := test_structure.LoadTerraformOptions(t，目录) terraform.Destroy(t，terraformOptions) })

1. 您的测试用例->测试

test_structure.RunTestStage(t，"TESTS"，func() ){ terraformOption := test_structure.LoadTerraformOptions(t，" Your /path/") //您的输出resourceGroupName := terraform.Output(t，terraformOptions，"resource_group_name") appName := terraform.Output(t，terraformOptions，"function_app_name") appId := terraform.Output(t，appId)"function_app_id") //您的函数//它可以接收t.Run("Test1"，func(t *testing.T) { testAzureResourceGroup(t，resourceGroupName，subscriptionID) }) t.Run("Test2"，func(t *testing.T) { testTerraformAzureFunctionApp(t，appId，appName) } })
