Alert rule in Azure ARM template not enabled in web test

I am using an ARM template to programmatically create an Application Insights web test and alert rule. The ARM template is based on this article.

Both the web test and the alert rule are created, but the Alerts property of the web test is disabled. The alert rule is listed on the Alert rules blade, however not in the Webtests section, but in the Others section, see picture:

enter image description here

What am I missing in order to get a web test with an enabled alert?

ARM template (the value of WebTest property was removed by SO):

It turned out the value of resourceUri is case-sensitive. Solution:

"variables": {
    ...
    "testName": "[toLower(concat(parameters('webTestName'), '-', toLower(parameters('appName'))))]",
    "alertRuleName": "[toLower(concat(parameters('webTestName'), '-', toLower(parameters('appName')), '-', subscription().subscriptionId))]"
},
