- TestTerragruntExample: Use OutputAll instead of Output because terragrunt returns all outputs in the full JSON format even when a specific key is requested - TestTerragruntMultiModuleExample: Copy the parent folder including modules since terragrunt.hcl files reference ../modules
Move test/terragrunt_example_test.go to modules/terragrunt/ since it's terragrunt-related. Also fix test isolation by copying examples to temp folders to avoid state conflicts between parallel test runs.
