Cannot run tests from Github Actions - ""tofu": executable file not found in $PATH; } "

[mrybson]

Describe the bug
I am trying to run the terratests from Github Actions. It works fine locally, but I am getting below error when running from the GH Runner.

To Reproduce

name: Integration Tests
on:
  workflow_dispatch
jobs:
  go-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - uses: actions/setup-go@v5
        with:
          go-version: '1.21'
      
      - name: Create module
        working-directory: terraform/tests
        run: go mod init "mymod"  
      
      - name: Go mod tidy
        working-directory: terraform/tests
        run: go mod tidy
 
      - name: Run Tests
        working-directory: terraform/tests
        run: go test -v -tags mytag

Expected behavior
Tests are getting executed.

Versions

• Terratest version: v0.46.11
• Environment details : ubuntu 22.04

** Additional **
I don't want to use tofu. I want to use terraform. I tried installing terraform as part of the Github action workflow, but that does not make any difference.

I had a similar problem locally. The same error occurred when the terraform command was not available in the terminal. Make sure that Terraform is installed and the path to the directory where the Terraform executable exists is in the PATH environment variable. Try running the terraform --version command via the workflow to verify it
