如何使用自定义的"terraform apply“命令实现terratest(golang)？

Question

我使用以下行来运行我的terraform计划&在示例/文件夹中应用：

"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"

它们运行得很好&我可以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

如何使用上述定制的terraform命令在Golang/terratest中测试？这是我的金线测试地形模块。

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)

在运行"go test -v test/S3-bucket_test.go“时，我得到了以下错误：

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

如何为金刚测试定制"terraform apply“，以便他们能够运行计划&成功地应用？

帮助感激！

要摆脱神秘的，“参数”区域是必需的，但没有设置。“错误”。我按照以下方式运行测试，区域错误消失了：

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

我找不到任何文档来更改terraform.InitAndApply(t，terraformOptions)行为。
