How do I implement terratest(golang) with customized "terraform apply" command?

问题

我使用以下代码行在example/文件夹中运行我的terraform plan和apply:

"aws-vault exec sandbox-admin-role --region=us-east-2 -- terraform plan -out=tfplan --var-file=customized.us-east-2.tfvars"
"aws-vault exec sandbox-admin-role --region=us-east-2 -- terraform apply --auto-approve tfplan"

它们运行良好,我可以使用类似的命令销毁它:

aws-vault exec sandbox-admin-role --region=us-east-2 -- terraform destroy --auto-approve --var-file=customized.us-east-2.tfvars

我如何在Golang/terratest中使用自定义的terraform命令进行测试,类似上面的命令?

这是我用于测试terraform模块的Golang代码:

package test
...
...
func TestTerraformAwsS3Example(t *testing.T) {
    t.Parallel()
...
    terraformOptions := terraform.WithDefaultRetryableErrors(t, &terraform.Options{
        TerraformDir: "../examples",
        VarFiles:     []string{"customized.us-east-2.tfvars"},
    })
    
    defer terraform.Destroy(t, terraformOptions)
    
    terraform.InitAndApply(t, terraformOptions)

当我运行"go test -v test/s3-bucket_test.go"时,我得到以下错误:

TestTerraformAwsS3Example 2022-03-01T19:14:33-06:00 logger.go:66: Terraform has been successfully initialized!

The argument "region" is required, but was not set.

我如何自定义"golang test"中的"terraform apply",以便它们可以成功运行plan和apply?

感谢您的帮助!

英文:

I use the following lines to run my terraform plan & apply in example/ folder:

"aws-vault exec sandbox-admin-role --region=us-east-2 -- terraform plan -out=tfplan --var-file=customized.us-east-2.tfvars"
"aws-vault exec sandbox-admin-role --region=us-east-2 -- terraform apply --auto-approve tfplan"

They are running fine & I can destroy it with similar command:

aws-vault exec sandbox-admin-role --region=us-east-2 -- terraform destroy --auto-approve --var-file=customized.us-east-2.tfvars

How do I test it in Golang/terratest with customized terraform command like above?
This is my golang lines testing the the terraform module.

package test
...
...
func TestTerraformAwsS3Example(t *testing.T) {
	t.Parallel()
...
    terraformOptions := terraform.WithDefaultRetryableErrors(t, &terraform.Options{
    	TerraformDir: "../examples",
    	VarFiles:     []string{"customized.us-east-2.tfvars"},
    })
    
    defer terraform.Destroy(t, terraformOptions)
    
    terraform.InitAndApply(t, terraformOptions)

And I got the following errors when running "go test -v test/s3-bucket_test.go":

TestTerraformAwsS3Example 2022-03-01T19:14:33-06:00 logger.go:66: Terraform has been successfully initialized!

The argument "region" is required, but was not set.

How do I customize "terraform apply" for the golang test so they could run plan&apply successfully?

Help appreciated!

为了摆脱神秘的“需要设置参数'region',但未设置”的错误,我按照以下方式运行了测试,成功解决了region错误:

% aws-vault exec sandbox-admin-role --region=us-east-2 -- go test -v tests/s3-bucket_test.go

我找不到任何关于更改terraform.InitAndApply(t, terraformOptions)行为的文档。

To get rid of the mysterious "The argument "region" is required, but was not set." error. I run the test as follows, the region error is gone:

% aws-vault exec sandbox-admin-role --region=us-east-2 -- go test -v tests/s3-bucket_test.go

I could not find any documentation to alter the terraform.InitAndApply(t, terraformOptions) behavior.
