From f617bb4206cfcb9dc02b852e70deebf79ac38e02 Mon Sep 17 00:00:00 2001 From: James Anderson Date: Fri, 13 Feb 2026 17:29:25 +0000 Subject: [PATCH 1/2] Add comprehensive tests for credential persistence and file discovery This commit adds two new test files to validate credential persistence functionality and expose a critical bug affecting beta customers. New test files: - CredentialPersistence.Tests.ps1: Unit tests for credential file persistence, encryption/decryption, and .dat file extension validation - SessionCredentialDiscovery.Tests.ps1: Integration tests for credential file discovery logic in Test-NctSession, including regression tests for the file extension mismatch bug Key tests added: - Validates credentials are saved with .dat extension - Confirms .dat files are discoverable with correct filter - Demonstrates bug: .txt filter fails to find .dat files - Tests username extraction from filenames - Validates DPAPI encryption security - Tests edge cases and multi-user scenarios These tests expose a critical bug where Test-NctSession searches for *.txt files but New-NctApiCredential saves *.dat files, causing persisted credentials to never be discovered.

Issue: - New-NctApiCredential saves credentials as: username.dat - Test-NctSession searched for: *.txt files - Result: Persisted credentials were never discovered Impact on beta customers: - Users who persisted credentials had to re-enter passwords every session - The main feature (removing need to store passwords in scripts) appeared broken - Created confusion as credential files existed but weren't detected Fix: - Changed filter in Test-NctSession.ps1 line 47 from "*.txt" to "*.dat" - Updated comment to say "credential files" instead of "text files" Testing: - All 11 credential discovery tests pass - Validates .dat files are now found correctly - Confirms .txt files are properly ignored This is the highest priority fix for beta customers as it restores core functionality for credential persistence.
