- Add Utilities.Tests.ps1: Format-* and Confirm-IpAddress* unit tests - Add Health.Tests.ps1: provisioning/configuration state, MAC duplicate detection - Expand NetworkController.Tests.ps1: Get-SdnGateway, Get-SdnLoadBalancerMux, Get-SdnResource - Replace all mock data with consistent DVLAB-prefixed randomized names - Update RunTests.ps1: add -Tag and -TestFile parameters, handle wrapped JSON - Add CONTRIBUTING_TESTS.md: instructions for adding new Pester tests - Update README.md: document new runner options, link to CONTRIBUTING_TESTS.md Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
- Add 'Pester Tests' workflow (pester-tests.yml): runs offline tests on every push to main and every PR targeting main - Add 'Run Offline Pester Tests' step to build-pipeline.yml so tests gate the publish step Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
Online tests required a live SDN environment on a self-hosted runner and are no longer maintained. All validation is now covered by the offline mock-based Pester tests. Removed: - .github/workflows/server2019-sdntest.yml - .github/workflows/server2019-sdntest-pr.yml - tests/online/ (RunTests.ps1, config sample, wave1/, waveAll/) Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
- Create .github/instructions/pester-tests.instructions.md with full skill guide (patterns, mock data, naming, CI, running tests) - Add Pester Testing section to .github/copilot-instructions.md - Remove online test references from CONTRIBUTING_TESTS.md (online tests were deleted in prior commit) Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
- .github/prompts/create-pester-test.prompt.md: reusable slash command to generate offline Pester tests for any function - .github/instructions/pester-review.instructions.md: code review rule that flags PRs adding/modifying functions without corresponding tests Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
Single prompt that creates a new function following project conventions AND generates its corresponding offline Pester tests in one invocation. Instructions files remain separate for passive context loading. - Remove: .github/prompts/create-pester-test.prompt.md - Add: .github/prompts/add-sdn-function.prompt.md Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d

- Use InModuleScope SdnDiagnostics for private utility functions - Use InModuleScope SdnDiag.NetworkController with Mock Invoke-RestMethodWithRetry for NC REST functions (nested module session state requires this pattern) - Fix MAC duplicate test @() wrapper for Group-Object single-result - Add outboundNatRules back-reference to LB mock data - Update instruction docs with correct mock patterns Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
- RunTests.ps1: add -PassThru and failure propagation - Workflows: route through RunTests.ps1 for consistent exit codes - Health.Tests.ps1: rewrite as data structure validation tests (direct invocation blocked by [TraceLevel] cross-module limitation) - CONTRIBUTING_TESTS.md: rewrite with accurate patterns and limitation docs - README.md: remove online test references, offline-only layout - add-sdn-function.prompt.md: fix module location table - pester-review.instructions.md: add manifest export check Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d
- pester-tests.instructions.md: add applyTo frontmatter for scope targeting - pester-tests.instructions.md: document singleton fixture exception (no wrapper) - add-sdn-function.prompt.md: note singleton format for config endpoints - copilot-instructions.md: fix Pattern B to correctly reference Invoke-RestMethodWithRetry - Utilities.Tests.ps1: add /0 CIDR edge case (documents known bit-shift limitation) Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d

- Fix Confirm-IpAddressInCidrRange: special-case prefix length 0 to avoid 32-bit shift wrap (modulo 32 made /0 behave like /32) - Update test to assert correct /0 behavior (Should -BeTrue) - Fix 'one assertion per It' rule to 'one behavior per It' in both pester-tests.instructions.md and CONTRIBUTING_TESTS.md - Fix BeforeAll mock guidance: mocks must live inside InModuleScope blocks, not in BeforeAll outside them Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: d38da7cf-014a-4a03-950b-4ba39152b58d

Summary
Overhauls the Pester test infrastructure to use offline (mock-based) tests with randomized data, adds CI pipeline execution, and removes the deprecated online/self-hosted runner workflows.
Changes
New test files
Expanded existing tests
Mock data
CI/CD
Runner improvements
Testing
Tests require the module to be built first (.\build.ps1), then run via .\tests\offline\RunTests.ps1.
