Question

我正在为terraform模块编写测试用例。我承担了一个角色，我想将其传递给我的考试。我不确定如何通过。我将其定义为const，然后如何传递它，以便在terraform init和terraform应用，销毁期间将其引发。

package test

import (
    "testing"

    "github.com/gruntwork-io/terratest/modules/aws"
    "github.com/gruntwork-io/terratest/modules/terraform"
    "github.com/stretchr/testify/assert"
    "github.com/stretchr/testify/require"
)


// An example of how to test the Terraform module in examples/terraform-aws-network-example using Terratest.
func TestTerraformAwsNetworkExample(t *testing.T) {
    t.Parallel()

    const authAssumeRoleEnvVar = "TERRATEST_IAM_ROLE"

    // Give the VPC and the subnets correct CIDRs
    vpcCidr := "1x.x.x.x/20"
    Env := "staging"
    privateSubnetCidr := []string{"1x.x.x.x/30"}
    publicSubnetCidr := []string{"1x.x.x.x/30"}
    Tag := map[string]string{"owner":"xxx"}
    awsRegion := "us-east-1"

    terraformOptions := &terraform.Options{
        // The path to where our Terraform code is located
        TerraformDir: "..",

        // Variables to pass to our Terraform code using -var options
        Vars: map[string]interface{}{
            "vpc_cidr":       vpcCidr,
            "env": Env,
            "private_subnet_cidrs": privateSubnetCidr,
            "public_subnet_cidrs":  publicSubnetCidr,
            "tags" : Tag,
        },

        EnvVars: map[string]string{
                 "AWS_DEFAULT_REGION": awsRegion,

        },
    }

    // At the end of the test, run `terraform destroy` to clean up any resources that were created
    defer terraform.Destroy(t, terraformOptions)

    // This will run `terraform init` and `terraform apply` and fail the test if there are any errors
    terraform.InitAndApply(t, terraformOptions)

    // Run `terraform output` to get the value of an output variable
    publicSubnetId := terraform.Output(t, terraformOptions, "public_subnet_ids")
    privateSubnetId := terraform.Output(t, terraformOptions, "private_subnet_ids")
    vpcId := terraform.Output(t, terraformOptions, "vpc_id")

    subnets := aws.GetSubnetsForVpc(t, vpcId, awsRegion)

    require.Equal(t, 2, len(subnets))
    // Verify if the network that is supposed to be public is really public
    assert.True(t, aws.IsPublicSubnet(t, publicSubnetId, awsRegion))
    // Verify if the network that is supposed to be private is really private
    assert.False(t, aws.IsPublicSubnet(t, privateSubnetId, awsRegion))
}

这段代码不可测试，因此您无法对其进行测试。

** https://github.com/gruntwork-io/terratest/blob/f3916f7a5f58e3fedf603388d3e3e8052d6a47a3/modules/aws/auth.go#L18

我希望他们可以像这样重构它：

var AuthAssumeRoleEnvVar string

func SetAuthAssumeRoleEnvVar(role string){
    AuthAssumeRoleEnvVar = role
}

func NewAuthenticatedSession(region string) (*session.Session, error) {
    if assumeRoleArn, ok := os.LookupEnv(AuthAssumeRoleEnvVar); ok {
        return NewAuthenticatedSessionFromRole(region, assumeRoleArn)
    } else {
        return NewAuthenticatedSessionFromDefaultCredentials(region)
    }
}

以便我们可以这样称呼它：

aws.SetAuthAssumeRoleEnvVar("testrole")
aws.NewAuthenticatedSession(region)

Answer 2

如文档中所述将TERRATEST_IAM_ROLE变量作为os环境变量传递的唯一方法您也可以将其定义为后端文件，但是如果您拥有断言的测试用例可以读取值，则该文件将不会被拾取，因为它使用aws cli

所以我做了一些事情，并且奏效了。

import (

    "os"


)
 os.Setenv("TERRATEST_IAM_ROLE", "arn:aws:iam::xxxx/xxxx")
