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

Question

我使用以下几行来运行我的 terraform 计划并在 example/ 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"

它们运行良好，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

我如何使用自定义的 terraform 命令在 Golang/terratest 中测试它？ 这是我的 golang 行测试 terraform 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)

运行“go test -v test/s3-bucket_test.go”时出现以下错误：

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

如何为 golang 测试自定义“terraform apply”，以便他们可以成功运行 plan&apply？

摆脱神秘的“需要参数“区域”，但未设置。” 错误。 我按如下方式运行测试，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改变terraform.InitAndApply(t, terraformOptions)行为。
