Terratest 在 Mac 上找不到 terraform

Question

I am trying to write a simple go test as follows

import (
    "testing"

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

func TestCoreInfoOutput(t *testing.T) {
    terraformOptions := &terraform.Options{
        TerraformDir: "../examples/output.tf",
    }

    defer terraform.Destroy(t, terraformOptions)

    terraform.InitAndApply(t, terraformOptions)

    output := terraform.Output(t, terraformOptions, "test_name_prefix")
    assert.Equal(t, "dev-use1-hello_world-", output)
}

But when I run go test my_test.go I get the following error

    apply.go:13: 
            Error Trace:    apply.go:13
                                        my_test.go:17
            Error:          Received unexpected error:
                            FatalError{Underlying: fork/exec /usr/local/bin/terraform: not a directory}
            Test:           TestCoreInfoOutput
    destroy.go:11: 
            Error Trace:    destroy.go:11
                                        panic.go:615
                                        testing.go:657
                                        apply.go:13
                                        core-info_test.go:17
            Error:          Received unexpected error:
                            FatalError{Underlying: fork/exec /usr/local/bin/terraform: not a directory}
            Test:           my_Test
FAIL

Here is the folder structure

--module 
    --core-info
      --examples
        --core-info.tf
        --output.tf
      --test
         my_test.go

I basically want to test the output values in output.tf in my test.

EDIT:

After I changed the file to be a directory of the file it fails with the follwong error

TerraformDir option should be set to a folder path and not a file path.

    TerraformDir: "../examples",

"../examples/output.tf" is not a folder path
