# Azure Verified Terraform Module Test Helper
|
|
|
|
|
|
|
|
|
|
This repo contains two helper functions that were used to test Azure Verified Terraform Module.
|
|
|
|
For End-End test:
|
|
|
|
```go
|
|
func TestExamplesStartup(t *testing.T) {
|
|
vars := map[string]interface{}{
|
|
"client_id": "",
|
|
"client_secret": "",
|
|
}
|
|
managedIdentityId := os.Getenv("MSI_ID")
|
|
if managedIdentityId != "" {
|
|
vars["managed_identity_principal_id"] = managedIdentityId
|
|
}
|
|
test_helper.RunE2ETest(t, "../../", "examples/startup", terraform.Options{
|
|
Upgrade: true,
|
|
Vars: vars,
|
|
}, func(t *testing.T, output test_helper.TerraformOutput) {
|
|
aksId, ok := output["test_aks_id"].(string)
|
|
assert.True(t, ok)
|
|
assert.Regexp(t, regexp.MustCompile("/subscriptions/.+/resourceGroups/.+/providers/Microsoft.ContainerService/managedClusters/.+"), aksId)
|
|
})
|
|
}
|
|
```
|
|
|
|
The `RunE2ETest` function accept module's root path, sub-folder to example code that our test want to apply, a `terraform.Options` argument, and an assertion callback.
|
|
|
|
In E2E test we apply the example code,then we execute `terraform output` and pass the json format output to this assertion callback, you can assert whether the output meets your spec there.
|
|
|
|
For Version-Upgrade Test:
|
|
|
|
```go
|
|
func TestExampleUpgrade_startup(t *testing.T) {
|
|
currentRoot, err := test_helper.GetCurrentModuleRootPath()
|
|
if err != nil {
|
|
t.FailNow()
|
|
}
|
|
currentMajorVersion, err := test_helper.GetCurrentMajorVersionFromEnv()
|
|
if err != nil {
|
|
t.FailNow()
|
|
}
|
|
vars := map[string]interface{}{
|
|
"client_id": "",
|
|
"client_secret": "",
|
|
}
|
|
managedIdentityId := os.Getenv("MSI_ID")
|
|
if managedIdentityId != "" {
|
|
vars["managed_identity_principal_id"] = managedIdentityId
|
|
}
|
|
test_helper.ModuleUpgradeTest(t, "Azure", "terraform-azurerm-aks", "examples/startup", currentRoot, terraform.Options{
|
|
Upgrade: true,
|
|
Vars: vars,
|
|
}, currentMajorVersion)
|
|
}
|
|
```
|
|
|
|
The `ModuleUpgradeTest` function accept your Github repo's owner name (could be username or org name), repo name, sub-folder to example code, and module's current major version (eg: v3.0.0 major version is 3).
|
|
|
|
The `ModuleUpgradeTest` function will clone and checkout the latest released tag version within the major version you've passed, apply the code in a temp directory, then modify the module's source to the current path, then execute `terraform plan` to see if there would be any drift in the plan. |
