CentralDbTestEnvironment sets five process-wide environment variables, and
Program's AddEnvironmentVariables() reads them at an unpredictable point during
host boot. With xUnit collection parallelization on, one fixture's teardown
could clear a var mid-boot for a sibling. Since the secrets adoption (G-4)
three of those keys are ${secret:...} references that fail closed, turning a
previously benign empty value into a SecretNotFoundException that aborts the
boot — an intermittent CI failure.
Adds a HostBootCollection that serializes every fixture booting a real host
while depending on that shared state, folding in the narrower "ActorSystem"
collection so its members stay serialized with each other as before. Site-role
fixtures stay parallel: they call Configuration.Sources.Clear(), dropping the
env-var provider, so they cannot participate in the race.
CentralDbTestEnvironment now also fails fast if two instances are ever live at
once, making a regression (a fixture added outside the collection) deterministic
rather than intermittent — this is what surfaced the disposed-CTS defect fixed
in the previous commit. Fixture teardown is try/finally so a throwing host
teardown can no longer strand the vars for the rest of the run.
Cost: Host.Tests runs ~2m30s -> ~4m10s; the serialized Central-boot classes are
most of the assembly's parallelism.
Fixes: Gitea #15
Switch the three literal ${SCADABRIDGE_*} placeholders in appsettings.Central.json
to ${secret:} references resolved by the pre-host secrets expander, and update the
_secrets doc note. Fix Host.Tests fixtures that boot the real Program pipeline against
Central config: CentralDbTestEnvironment now also supplies the LDAP service-account
password and JWT signing key as whole-key env overrides (rollback path) so the expander
skips the tokens without a seeded store; the three fixtures that managed env vars
inline now use CentralDbTestEnvironment.
REQ-HOST-3/REQ-HOST-4 require a MachineDataDb connection string for Central nodes.
The shipped docker appsettings (docker/central-node-a/appsettings.Central.json and
central-node-b) already carry the key. Host-008 had removed the fail-fast Require
because MachineDataDb had no consumer yet; this commit reverses that decision so a
misconfigured or missing connection string is caught at startup with a clear error.
Changes:
- DatabaseOptions: add MachineDataDb property with XML doc comment
- StartupValidator: add .Require for ScadaBridge:Database:MachineDataDb inside the
existing Central .When block, immediately after the ConfigurationDb Require
- StartupValidatorTests: rename Central_MissingMachineDataDb_PassesValidation ->
FailsValidation and flip to Assert.Throws; update comment to cite REQ-HOST-3/4,
shipped docker appsettings, and the Host-008 reversal; add MachineDataDb to
ValidCentralConfig() so all other Central tests remain green
- CentralDbTestEnvironment: supply ScadaBridge__Database__MachineDataDb env var
(mirrors ConfigurationDb pattern) so HostStartupTests, HealthCheckTests, and
MetricsEndpointTests pass through the new Require
- CompositionRootTests, AkkaHostedServiceAuditWiringTests, ActorPathTests: set
ScadaBridge__Database__MachineDataDb env var alongside the pepper env var and
clear it in Dispose, matching the existing pepper handling pattern
Build: 0 warnings, 0 errors. dotnet test Host.Tests: 233/233 passed.
Replace dc=scadabridge,dc=local with dc=zb,dc=local in all dev/test LDAP
references — app config, docker test-cluster node configs (docker/ and
docker-env2/), GLAuth fixture, dev tooling, Host.Tests fixtures,
IntegrationTests factory, and operational test_infra docs. OU structure
(ou=SCADA-Admins,ou=users,etc.) preserved throughout. Email domains
(@scadabridge.local), hostnames, and container names are untouched.
Historical plan docs (2026-05-24-second-environment.md,
2026-05-31-folder-repo-rename-scadabridge-design.md) excluded as
point-in-time records. No synthetic dc=example,dc=com placeholders touched.
Commit 1fcc4f5 added a Central-only Require for ScadaBridge:InboundApi:ApiKeyPepper
(>=16 chars) to StartupValidator. That Require fires in Program.cs before WebApplicationFactory
can apply any WithWebHostBuilder config overlays, so it must be satisfied via environment
variables (which ARE in the pre-host AddEnvironmentVariables() pass).
Fix (test-only, no src/ changes):
- CentralDbTestEnvironment: add ScadaBridge__InboundApi__ApiKeyPepper env var (TestPepper
constant, 23 chars) alongside the existing db connection string; restore on Dispose.
Fixes HealthCheckTests, MetricsEndpointTests, and HostStartupTests.CentralRole_StartsWithoutError
which all use CentralDbTestEnvironment.
- CentralActorPathTests.InitializeAsync: set the pepper env var before WebApplicationFactory
is constructed (the class uses IAsyncLifetime directly, not CentralDbTestEnvironment).
- CentralCompositionRootTests ctor + Dispose: same env-var pattern; those tests already had
the pepper in AddInMemoryCollection (DI-layer only, too late for pre-host validation).
- CentralAuditWiringTests ctor + Dispose: same env-var pattern for the same reason.
- StartupValidatorTests.ValidCentralConfig(): add pepper so the unit tests that call
StartupValidator.Validate() directly with a Central config stop failing.
- Add guard tests: Central_MissingApiKeyPepper_FailsValidation,
Central_ShortApiKeyPepper_FailsValidation, Site_ApiKeyPepper_NotRequired — these lock
the production behavior introduced by 1fcc4f5.
