Pull Request (PR) description

  • Added post-installation configuration integration test to configure SSL certificate
    support for SQL Server instance DSCSQLTEST in CI environment, enabling testing
    of encryption-related functionality. The new PostInstallationConfiguration
    integration test includes:
    • Self-signed SSL certificate creation and installation
    • Certificate configuration for SQL Server Database Engine
    • Service account permissions for certificate private key access
    • Certificate trust chain configuration
    • Verification that encryption is properly configured
    • Enabled previously skipped encryption tests in Invoke-SqlDscQuery
    • Added integration tests for Connect-SqlDscDatabaseEngine command to verify
      the -Encrypt parameter functionality
      issue #2290.

This Pull Request (PR) fixes the following issues

Task list

Walkthrough

Adds a post-installation integration test that configures a self-signed SSL certificate for the DSCSQLTEST SQL Server in CI, reorders pipeline tests to run it after installation, enables and extends encryption tests (Encrypt parameter) across integration suites, updates test README and CHANGELOG, and preserves Agent XPs around a config test.

Changes

Cohort / File(s) Summary
CI Pipeline
azure-pipelines.yml
Inserts PostInstallationConfiguration.Integration.Tests.ps1 into the integration test sequence after Install-SqlDscServer, moves Invoke-SqlDscQuery.Integration.Tests.ps1 earlier, and adjusts Group/run-order labels.
Post-install encryption setup tests
tests/Integration/Commands/PostInstallationConfiguration.Integration.Tests.ps1, tests/Integration/Commands/README.md
Adds PostInstallationConfiguration.Integration.Tests.ps1 to create/import a self-signed SSLServerAuthentication certificate, add it to Trusted Root, grant the SQL service account private-key read access, bind the cert via registry, restart SQL Server, verify service and TLS setup, and document run order/dependencies in README.
Encryption test enablement & coverage
tests/Integration/Commands/Invoke-SqlDscQuery.Integration.Tests.ps1, tests/Integration/Commands/Connect-SqlDscDatabaseEngine.Integration.Tests.ps1
Removes the skip for the -Encrypt case in Invoke-SqlDscQuery and adds explicit -Encrypt assertions in Connect-SqlDscDatabaseEngine across impersonation, named-instance, and SQL-login scenarios with proper Disconnect cleanup.
Configuration option test safety
tests/Integration/Commands/Get-SqlDscConfigurationOption.Integration.Tests.ps1
Adds setup/teardown to capture the current Agent XPs value, ensure it is set to 1 for the test, and restore the original value afterward.
Changelog
CHANGELOG.md
Replaces prior Added entry with a consolidated description covering the new post-install SSL configuration integration test and related test ordering/encryption changes; removes the standalone Get-SqlDscDatabasePermission test mention.

❌ Failed checks (1 warning)
Check name Status Explanation Resolution
Out of Scope Changes Check ⚠️ Warning The change to Get-SqlDscConfigurationOption.Integration.Tests.ps1 introduces Agent XPs setup and teardown logic unrelated to the SSL certificate or encryption objectives in issue #2290, representing an out-of-scope addition to this PR. Please remove or isolate the Agent XPs setup/teardown changes from this PR and submit them separately to keep the SSL certificate integration test scope focused on encryption support.
✅ Passed checks (4 passed)
Check name Status Explanation
Title Check ✅ Passed The title succinctly describes the primary change of adding integration tests for SSL certificate setup without extraneous detail and aligns directly with the main functionality introduced in the changeset.
Linked Issues Check ✅ Passed The pull request implements the linked issue #2290 objectives by generating and installing a self-signed SSL certificate, binding it to the DSCSQLTEST instance via registry updates, restarting the service, importing the certificate into the trusted store, enabling and adding encryption tests (Connect-SqlDscDatabaseEngine and Invoke-SqlDscQuery), and verifying encrypted connections through DMV queries, thereby satisfying all technical requirements.
Description Check ✅ Passed Because the description clearly outlines the new SSL certificate integration test functionality and references the relevant issue and checklist items, it is directly related to the changeset and passes validation.
Docstring Coverage ✅ Passed No functions found in the changes. Docstring coverage check skipped.

1-211: LGTM! All previous issues have been addressed.

The integration test is well-structured and correctly implements SSL certificate configuration for the DSCSQLTEST instance. All previously flagged issues have been resolved:

  • ✓ Uses Get-ComputerName for CI compatibility (lines 37-38)
  • ✓ Uses ::new() instead of New-Object for .NET objects (lines 111-115)
  • ✓ Includes -ErrorAction 'Stop' on all critical operations (lines 71, 81, 88, 97, 110, 117, 120, 138, 141, 149, 156, 171, 177, 186, 199, 207)
  • ✓ Correctly avoids enabling ForceEncryption to support both encrypted and non-encrypted connection testing (per learnings)
  • ✓ Follows required integration test setup pattern (lines 1-30)
  • ✓ Uses Pester v5 syntax throughout with proper naming conventions
  • ✓ Verifies encryption via DMV query (lines 180-211) as specified in issue Add encryption support for SQL Server instance DSCSQLTEST in CI environment #2290

The test comprehensively covers the SSL certificate lifecycle: creation, export, trust chain configuration, service account permissions, SQL Server configuration, service restart, and connection verification with and without encryption.

**/*.[Tt]ests.ps1: # Tests Guidelines

Core Requirements

  • All public commands, private functions and classes must have unit tests
  • All public commands and class-based resources must have integration tests
  • Use Pester v5 syntax only
  • Test code only inside Describe blocks
  • Assertions only in It blocks
  • Never test verbose messages, debug messages or parameter binding behavior
  • Pass all mandatory parameters to avoid prompts

Requirements

  • Inside It blocks, assign unused return objects to $null (unless part of pipeline)
  • Tested entity must be called from within the It blocks
  • Keep results and assertions in same It block
  • Avoid try-catch-finally for cleanup, use AfterAll or AfterEach
  • Avoid unnecessary remove/recreate cycles

Naming

  • One Describe block per file matching the tested entity name
  • Context descriptions start with 'When'
  • It descriptions start with 'Should', must not contain 'when'
  • Mock variables prefix: 'mock'

Structure & Scope

  • Public commands: Never use InModuleScope (unless retrieving localized strings)
  • Private functions/class resources: Always use InModuleScope
  • Each class method = separate Context block
  • Each scenario = separate Context block
  • Use nested Context blocks for complex scenarios
  • Mocking in BeforeAll (BeforeEach only when required)
  • Setup/teardown in BeforeAll,BeforeEach/AfterAll,AfterEach close to usage

Syntax Rules

  • PascalCase: Describe, Context, It, Should, BeforeAll, BeforeEach, AfterAll, AfterEach
  • Use -BeTrue/-BeFalse never -Be $true/-Be $false
  • Never use Assert-MockCalled, use Should -Invoke instead
  • No Should -Not -Throw - invoke commands directly
  • Never add an empty -MockWith block
  • Omit -MockWith when returning $null
  • Set $PSDefaultParameterValues for Mock:ModuleName, Should:ModuleName, InModuleScope:ModuleName
  • Omit -ModuleName parameter on Pester commands

  • Avoid ExpectedMessage for Should -Throw assertions
  • Only run integration tests in CI unless explicitly instructed.
  • Call commands with -Force parameter where applicable (avoids prompting).
  • Use -ErrorAction 'Stop' on commands so failures surface immediately

**: # DSC Community Guidelines

Terminology

  • Command: Public command
  • Function: Private function
  • Resource: DSC class-based resource

Build & Test Workflow Requirements

  • Run PowerShell script files from repository root
  • Setup build and test environment (once per pwsh session): ./build.ps1 -Tasks noop
  • Build project before running tests: ./build.ps1 -Tasks build
  • Always run tests in new pwsh session: Invoke-Pester -Path @({test paths}) -Output Detailed

File Organization

  • Public commands: source/Public/{CommandName}.ps1
  • Private functions: source/Private/{FunctionName}.ps1
  • Unit tests: tests/Unit/{Classes|Public|Private}/{Name}.Tests.ps1
  • Integration tests: tests/Integration/Commands/{CommandName}.Integration.Tests.ps1

Requirements

  • Follow instructions over existing code patterns
  • Follow PowerShell style and test guideline instructions strictly
  • Always update CHANGELOG.md Unreleased section
  • Localize all strings using string keys; remove any orphaned string keys
  • Check DscResource.Common before creating private functions
  • Separate reusable logic into private functions
  • DSC resources should always be created as class-based resources
  • Add unit tests for all commands/functions/resources
  • Add integration tests for all public commands and resources

54-61: Split AfterAll into two blocks and add -ErrorAction 'Stop' to Disconnect.

The single AfterAll block has a reliability concern: if the restoration on line 58 throws, line 61 (Disconnect) won't execute, potentially leaving connections open. Pester executes all AfterAll blocks even if one fails, ensuring complete cleanup. Additionally, line 61 is missing -ErrorAction 'Stop' per integration test guidelines.

Apply this diff:

     AfterAll {
         # Restore the original value of 'Agent XPs' if it was not 1
         if ($script:originalAgentXPsValue -ne 1)
         {
             Set-SqlDscConfigurationOption -ServerObject $script:serverObject -Name 'Agent XPs' -Value $script:originalAgentXPsValue -Force -ErrorAction 'Stop'
         }

-        Disconnect-SqlDscDatabaseEngine -ServerObject $script:serverObject

97-97: Add -ErrorAction 'Stop' to certificate retrieval.

Line 97 retrieves the certificate for further ACL processing without -ErrorAction 'Stop'. Per integration test guidelines, commands should use -ErrorAction 'Stop' so failures surface immediately, especially when the result is used for critical downstream operations.

Apply this diff:

             # Get the certificate from the Personal store
-            $cert = Get-ChildItem -Path "Cert:\LocalMachine\My\$script:certificateThumbprint"
+            $cert = Get-ChildItem -Path "Cert:\LocalMachine\My\$script:certificateThumbprint" -ErrorAction 'Stop'

Based on learnings


212-213: Add AfterAll block to clean up certificate resources.

The test creates a certificate, exports it to a file, imports it to Trusted Root, and leaves these resources behind. Add an AfterAll block to clean up the certificate from both stores and delete the exported file to avoid resource leaks and interference with subsequent test runs.

Add this AfterAll block before the closing brace of the Context block:

        AfterAll {
            # Remove certificate from Trusted Root store
            if ($script:certificateThumbprint)
            {
                $trustedCert = Get-ChildItem -Path 'Cert:\LocalMachine\Root' -ErrorAction 'SilentlyContinue' |
                    Where-Object -FilterScript { $_.Thumbprint -eq $script:certificateThumbprint }

                if ($trustedCert)
                {
                    Remove-Item -Path "Cert:\LocalMachine\Root\$script:certificateThumbprint" -Force -ErrorAction 'Stop'
                }
            }

            # Remove certificate from Personal store
            if ($script:certificateThumbprint)
            {
                $personalCert = Get-ChildItem -Path 'Cert:\LocalMachine\My' -ErrorAction 'SilentlyContinue' |
                    Where-Object -FilterScript { $_.Thumbprint -eq $script:certificateThumbprint }

                if ($personalCert)
                {
                    Remove-Item -Path "Cert:\LocalMachine\My\$script:certificateThumbprint" -Force -ErrorAction 'Stop'
                }
            }
