Terratest 断言字符串因 GitHub 操作而失败

Question

Versions

• Terraform v0.13.5
• Go v1.15.2
• Terratest v0.30.23

Issue

I've created a test according to the Terratest Docs . The code for the test can be found below under the heading: iam_role_standard_test.go

When I run the test locally, everything works as expected.

However, I'm using GitHub Actions as my CI/CD tool. When the workflow job executes it fails with the following error (The workflow file is below under the heading workflow.yaml ):

Error Trace: iam_role_standard_test.go:63
Error: Not equal:
expected: "TestIamRole_dRGsKn"

Which, from what I can make out, is failing because "TestIamRole_dRGsKn" is compared to TestIamRole_dRGsKn which is not the same.

Question

How do I format the output from terraform so that the strings will be asserted as equal?

iam_role_standard_test.go

package test

import (
    "fmt"
    "testing"

    "github.com/stretchr/testify/assert"

)

func TestIamRole(t *testing.T) {

    uniqueId := random.UniqueId()
    expectedRoleName := fmt.Sprintf("TestIamRole_%s", uniqueId)

    // Retryable errors in terraform testing.
    terraformOptions := terraform.WithDefaultRetryableErrors(t, &terraform.Options{
        TerraformDir: "../path/to/terraform",

        Lock: true,

        // Configure backend to assume IamManager role
        BackendConfig: map[string]interface{}{

        },
    })

    defer terraform.Destroy(t, terraformOptions)

    // Deploy configuration
    terraform.InitAndApply(t, terraformOptions)

    // Capture outputs
    actualRoleName := terraform.Output(t, terraformOptions, "name")

    // Assert output vaules
    assert.Equal(t, expectedRoleName, actualRoleName)

Found the issue.

It's referenced in the issues of the terratest GitHub repo

Posting the answer here in case anyone else wastes a moment of their life on this!

Changing my workflow.yaml file solved it:

name: terratest
on: [ push ]
jobs:
    terratest:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-go@v2
        with:
          go-version: '^1.15.2'
      - uses: hashicorp/setup-terraform@v1
        with:
          terraform_version: 0.13.5
          terraform_wrapper: false
      - run: go mod init github.com/my-org/my-repo
      - run: go test -v -count=1 -timeout 30m
