Pattern: Missing tests for DSC

Issue: -

Description

Every DSC resource module should contain folder Tests with tests for every resource. Test scripts should have resource name they are testing in the file name.

How

To fix a violation of this rule, please make sure Tests directory is present:

  • For non-class based resources it should exist at the same folder level as DSCResources folder.
  • For class based resources it should be present at the same folder level as resource psm1 file.

Tests folder should contain test script for given resource - file name should contain resource's name.

Non-class based resource

Let's assume we have non-class based resource with a following file structure:

  • xAzure
    • DSCResources
      • MSFT_xAzureSubscription
        • MSFT_xAzureSubscription.psm1
        • MSFT_xAzureSubscription.schema.mof

In this case, to fix this warning, we should add tests in a following way:

  • xAzure
    • DSCResources
      • MSFT_xAzureSubscription
        • MSFT_xAzureSubscription.psm1
        • MSFT_xAzureSubscription.schema.mof
    • Tests
      • MSFT_xAzureSubscription_Tests.ps1

Class based resource

Let's assume we have class based resource with a following file structure:

  • MyDscResource
    • MyDscResource.psm1
    • MyDscResource.psd1

In this case, to fix this warning, we should add tests in a following way:

  • MyDscResource
    • MyDscResource.psm1
    • MyDscResource.psd1
    • Tests
      • MyDscResource_Tests.ps1
