Drops a small helper for the gated live-integration tests that need
HISTORIAN_USER + HISTORIAN_PASSWORD set in the process environment
(currently GetTagMetadataAsync_ExplicitCredentials_AgainstLocalHistorian).
Three modes:
- Default: prompts for username (default <COMPUTERNAME>\<USERNAME>) and
password (silent), saves to %USERPROFILE%\.histsdk\credentials.xml via
Export-Clixml. The SecureString inside the PSCredential is DPAPI-encrypted
and decryptable only by the same Windows user account on the same machine.
- -Load: reads the saved credential and exports HISTORIAN_USER +
HISTORIAN_PASSWORD into the current PowerShell session's environment.
- -Clear: deletes the saved credential file.
Also accepts -Path to override the storage location (e.g. for keeping
multiple credential sets side by side) and -UserName to skip the username
prompt for password-only re-saves.
Stored under the user profile, never inside the repo, so it cannot be
committed accidentally. The file format is plain Export-Clixml — no custom
encoding shenanigans.
Live-verified locally: -Load + dotnet test passes the previously-skipped
GetTagMetadataAsync_ExplicitCredentials_AgainstLocalHistorian test against
the local Historian with IntegratedSecurity=false.
