Test cases for createUiDefinition.json

Grein
06/20/2024

This article describes the tests that are run with the template test toolkit for createUiDefinition.json files. The examples include the test names and code samples that pass or fail the tests.

The toolkit includes test cases for Azure Resource Manager templates (ARM templates) and the main template files named azuredeploy.json or maintemplate.json. When the directory contains a createUiDefinition.json file, specific tests are run for UI controls. For more information about how to run tests or how to run a specific test, see Test parameters.

The createUiDefinition.json file creates custom user-interface (UI) controls using elements and functions.

Verify template parameter allows values

Test name: Allowed Values Should Actually Be Allowed

This test checks that values for each control in createUiDefinition.json are allowed in the main template's parameters. The parameters are mapped by name between the main template and the createUiDefinition.json file.

The main template's parameter must accept the values from the control's allowedValues. The test also checks that the control is referenced in the createUiDefinition.json outputs section.

This test checks the main template and createUiDefinition.json file. An example of the createUiDefinition.json file is shown after the main template examples.

The following example fails because the main template's parameter name combo doesn't match the control's parameter name comboBox.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "combo": {
      "type": "string",
      "defaultValue": "two"
    }
  },
  "resources": [],
  "outputs": {
    "comboBoxOutput": {
      "type": "string",
      "value": "[parameters('combo')]"
    }
  }
}

The following example fails because the main template's parameter type int doesn't accept the control's string value. And if a main template's parameter defines a defaultValue it must be a valid value in the control's allowedValues.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "comboBox": {
      "type": "int",
      "defaultValue": 4
    }
  },
  "resources": [],
  "outputs": {
    "comboBoxOutput": {
      "type": "string",
      "value": "[parameters('combo')]"
    }
  }
}

The following example passes because the main template's parameter name matches the control's parameter name. And the template's parameter type is a string with a defaultValue that's specified in the control's allowedValues.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "comboBox": {
      "type": "string",
      "defaultValue": "two"
    }
  },
  "resources": [],
  "outputs": {
    "comboBoxOutput": {
      "type": "string",
      "value": "[parameters('comboBox')]"
    }
  }
}

The createUiDefinition.json file for this example:

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [],
    "steps": [
      {
        "name": "demoComboBox",
        "label": "demoComboBoxLabel",
        "elements": [
          {
            "name": "comboBox",
            "type": "Microsoft.Common.DropDown",
            "label": "Example drop down",
            "defaultValue": "Value two",
            "toolTip": "This is a tool tip",
            "constraints": {
              "allowedValues": [
                {
                  "label": "Value one",
                  "description": "The value to select for option 1.",
                  "value": "one"
                },
                {
                  "label": "Value two",
                  "description": "The value to select for option 2.",
                  "value": "two"
                }
              ],
              "required": true
            },
            "visible": true
          }
        ]
      }
    ],
    "outputs": {
      "comboBox": "[steps('demoComboBox').comboBox]"
    }
  }
}

Output controls must exist

Test name: Controls In Outputs Must Exist

Controls that are used in the outputs section must exist in an element elsewhere in createUiDefinition.json. The name referenced in outputs must match a name used in basics[] or steps[].

The following example fails.

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "nameDoesNotMatchOutput",
        "type": "Microsoft.Common.DropDown",
        "label": "Example drop down",
        "toolTip": "This is a tool tip"
      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]"
    }
  }
}

The following example passes.

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "comboBox",
        "type": "Microsoft.Common.DropDown",
        "label": "Example drop down",
        "toolTip": "This is a tool tip"
      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]"
    }
  }
}

Properties must include values

Test name: CreateUIDefinition Must Not Have Blanks

Properties must include values. Required properties must use valid values. Optional properties that are blank should be removed. The test allows blank "basics": [], "steps": [], or defaultValue.

The following example fails because label, placeholder, and toolTip are blank.

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "comboBox",
        "type": "Microsoft.Common.DropDown",
        "label": "",
        "placeholder": "",
        "defaultValue": "",
        "toolTip": ""
      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]"
    }
  }
}

The following example passes because label and toolTip have values, and placeholder was removed.

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",

        "label": "Example drop down",
        "defaultValue": "",
        "toolTip": "This is a tool tip"
      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]"
    }
  }
}

Use valid schema and version

Test name: CreateUIDefinition Should Have Schema

The createUiDefinition.json file must include a $schema property and use a valid $schema and version. The version numbers in $schema and version must match.

      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]",
      "location": "[location()]"
    }
  }
}

Include control outputs in template parameters

Test name: Outputs Must Be Present In Template Parameters

The test checks that createUiDefinition.json includes an outputs section. The test also checks that those outputs are defined in the main template's parameters section. The names must match because parameters are mapped by name between the createUiDefinition.json and the main template.

This test checks the main template and createUiDefinition.json file. An example of the createUiDefinition.json file is shown after the main template examples.

The following example fails because the main template doesn't include the comboBox parameter from the createUiDefinition.json file's outputs section.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "location": {
      "type": "string",
      "defaultValue": "[resourceGroup().location]"
    }
  },
  "resources": [],
  "outputs": {
    "location": {
      "type": "string",
      "value": "[parameters('location')]"
    }
  }
}

The following example passes because the main template includes the comboBox parameter.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "comboBox": {
      "type": "string",
      "defaultValue": "two"
    },
    "location": {
      "type": "string",
      "defaultValue": "[resourceGroup().location]"
    }
  },
  "resources": [],
  "outputs": {
    "comboBox": {
      "type": "string",
      "value": "[parameters('comboBox')]"
    },
    "location": {
      "type": "string",
      "value": "[parameters('location')]"
    }
  }
}

The createUiDefinition.json file for this example:

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "comboBox",
        "type": "Microsoft.Common.DropDown",
        "label": "Example drop down",
        "toolTip": "This is a tool tip"
      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]",
      "location": "[location()]"
    }
  }
}

Parameters without default must exist in outputs

Test name: Parameters Without Default Must Exist In CreateUIDefinition

Parameters in the main template without a default value must exist in the createUiDefinition.json file's outputs section.

This test checks the main template and createUiDefinition.json file. An example of the azuredeploy.json file is shown after the control's examples.

The following example fails because the createUiDefinition.json file's outputs doesn't include the main template's parameter comboBox.

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "comboBox",
        "type": "Microsoft.Common.DropDown",
        "label": "Example drop down",
        "toolTip": "This is a tool tip"
      }
    ],
    "steps": [],
    "outputs": {
      "location": "[location()]"
    }
  }
}

The following example passes because createUiDefinition.json includes the comboBox in outputs.

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "comboBox",
        "type": "Microsoft.Common.DropDown",
        "label": "Example drop down",
        "toolTip": "This is a tool tip"
      }
    ],
    "steps": [],
    "outputs": {
      "comboBox": "[basics('comboBox')]",
      "location": "[location()]"
    }
  }
}

The azuredeploy.json file for this example. The comboBox parameter doesn't have a default value.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "comboBox": {
      "type": "string"
    },
    "location": {
      "type": "string"
    }
  },
  "resources": [],
  "outputs": {
    "comboBox": {
      "type": "string",
      "value": "[parameters('comboBox')]"
    },
    "location": {
      "type": "string",
      "value": "[parameters('location')]"
    }
  }
}

Use secure parameter with password box

Test name: Password Textboxes Must Be Used For Password Parameters

This test checks that a Microsoft.Common.PasswordBox element is defined in the main template's parameters and the createUiDefinition.json outputs. The main template's parameter type for a password box must be secureString or secureObject.

This test checks the main template and createUiDefinition.json file. An example of the createUiDefinition.json file is shown after the main template examples.

The following example fails because the main template's passwordBox parameter is a string.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "passwordBox": {
      "type": "string"
    },
    "location": {
      "type": "string"
    }
  },
  "resources": [],
  "outputs": {
    "location": {
      "type": "string",
      "value": "[parameters('location')]"
    }
  }
}

The following example passes because the main template's passwordBox parameter is a secureString.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "passwordBox": {
      "type": "secureString"
    },
    "location": {
      "type": "string"
    }
  },
  "resources": [],
  "outputs": {
    "location": {
      "type": "string",
      "value": "[parameters('location')]"
    }
  }
}

The createUiDefinition.json file for this example:

{
  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "passwordBox",
        "type": "Microsoft.Common.PasswordBox",
        "label": {
          "password": "Password",
          "confirmPassword": "Confirm password"
        },
        "toolTip": "Type a password"
      }
    ],
    "steps": [],
    "outputs": {
      "location": "[location()]",
      "passwordBox": "[basics('passwordBox')]"
    }
  }
}

Password box requires minimum length

Test name: PasswordBoxes Must Have Min Length

The test checks that the Microsoft.Common.PasswordBox element uses constraints with a regex that requires at least 12 characters.

Virtual machine sizes must match

Test name: VM Sizes Must Match Template

This test checks that the Microsoft.Compute.SizeSelector is in the createUiDefinition.json outputs and the main template's parameters section. Main template parameters that specify a defaultValue must match a value in the control's allowedSizes.

This test checks the main template and createUiDefinition.json file. An example of the createUiDefinition.json file is shown after the main template examples.

The following example fails because the main template's defaultValue doesn't match a value in allowedSizes.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "location": {
      "type": "string"
    },
    "vmSize": {
      "type": "string",
      "defaultValue": "Standard_D9"
    }
  },
  "resources": [],
  "outputs": {
    "location": {
      "type": "string",
      "value": "[parameters('location')]"
    },
    "vmSize": {
      "type": "string",
      "value": "[parameters('vmSize')]"
    }
  }
}

The following example passes because the main template's defaultValue matches a value in allowedSizes.
