Reviewer of Bundle C (#23 M1) flagged two blockers in the
AddAuditLogTableMigration integration tests:
1. Tests used 'if (!await EnsureMigrationApplied()) return;' which made
the xunit runner report them as Passed when the dev MSSQL container
was absent — a CI false-positive risk. xunit 2.9.x does NOT ship the
v3 Assert.Skip/SkipUnless/SkipWhen API surface (verified empirically
against xunit.assert 2.9.3 — only v3.x exposes those static methods),
so the canonical xunit-v2 equivalent is the Xunit.SkippableFact
package. Replaced [Fact] with [SkippableFact] and the early-return
pattern with 'Skip.IfNot(_fixture.Available, _fixture.SkipReason)' as
the first statement of each of the 8 audit-log test methods. The
runner now reports them as Skipped (not Passed) when MSSQL is down.
2. MsSqlMigrationFixture relied on SqlClient's 30s default connect
timeout, so a no-container fixture construction hung ~30s. Added
'Connect Timeout=3' to DefaultAdminConnectionString. Verified
fail-fast under ~4s end-to-end with a bad host via env-var override.
Additional fixture cleanups:
- Migration is now applied once in the fixture constructor (was per-test
via EnsureMigrationApplied for idempotency). Tests reach a fully-
migrated database with no extra setup. Removed the now-unused
EnsureMigrationApplied helper from the test class.
- Constructor narrowed its catch to SqlException + InvalidOperationException
for the OpenAsync step (the only legitimate connect-failure surfaces);
everything else (CREATE DATABASE, MigrateAsync) is treated as a hard
fixture failure and bubbles up. Added a best-effort
TryDropOrphanDatabase() pre-throw cleanup so partial construction
cannot leak guid-suffixed databases.
- Stale doc comments referencing the (non-existent) xunit 2.9.x Skip
shim removed; replaced with accurate notes about Xunit.SkippableFact.
Verified:
- dotnet build ScadaLink.slnx: clean (0 warnings, 0 errors).
- dotnet test ScadaLink.ConfigurationDatabase.Tests with MSSQL up:
Passed 150 / Skipped 0 / Failed 0.
- Same suite with SCADALINK_MSSQL_TEST_CONN pointed at a closed port:
the 8 AddAuditLogTableMigration tests report as Skipped (visible
'[SKIP]' lines in runner output), total elapsed ~3s.
Files touched:
- Directory.Packages.props: added Xunit.SkippableFact 1.5.61.
- tests/ScadaLink.ConfigurationDatabase.Tests/ScadaLink.ConfigurationDatabase.Tests.csproj:
added the SkippableFact PackageReference.
- tests/ScadaLink.ConfigurationDatabase.Tests/Migrations/MsSqlMigrationFixture.cs:
Connect Timeout=3, constructor refactor, doc-comment fixes.
- tests/ScadaLink.ConfigurationDatabase.Tests/Migrations/AddAuditLogTableMigrationTests.cs:
[SkippableFact] + Skip.IfNot pattern across all 8 tests.
Untouched (per reviewer guidance):
- Migration file (Bundle C main artifact unchanged).
- Bundle B reconciliation (composite PK + UX_AuditLog_EventId).
- SqlClient VersionOverride 6.1.1 in the test csproj.
- infra/* (separate uncommitted local edits remain in working tree).
