PR Title and Description Quality

The PR title and description are clear and well-structured. The objective clearly explains what is being added (Sourcery support for BitwardenKit) and why. The PR references the appropriate Jira ticket.

Summary of Changes

This PR adds Sourcery support to BitwardenKit, enabling automatic mock generation for protocols marked with // sourcery: AutoMockable. The implementation follows the same pattern already established in BitwardenShared and AuthenticatorShared.

Key changes:

• Added Sourcery configuration (sourcery.yml) for BitwardenKit
• Added .gitignore for generated mock files
• Integrated Sourcery into the build process via project-bwk.yml
• Removed manual MockActiveAccountStateProvider in favor of auto-generated mock
• Updated ErrorReportBuilderTests.swift to use the auto-generated mock from BitwardenKitMocks
• Minor whitespace fix in FeatureFlag.swift (trailing whitespace removal)

Findings

Finding 1: BitwardenKit Sourcery configuration lacks consistency with sibling projects (🎨)

The sourcery.yml for BitwardenKit specifies different imports than BitwardenShared and AuthenticatorShared:

BitwardenKit (BitwardenKit/Sourcery/sourcery.yml:16-18):

args:
  autoMockableImports: ["Combine"]
  autoMockableTestableImports: ["BitwardenKit"]

BitwardenShared (BitwardenShared/Sourcery/sourcery.yml:16-18):

args:
  autoMockableImports: ["BitwardenKit", "BitwardenSdk", "Combine"]
  autoMockableTestableImports: ["BitwardenShared"]

Analysis: BitwardenKit's configuration is correct for its current needs since it only depends on Combine and doesn't use BitwardenSdk. However, the pattern suggests BitwardenKit is a lower-level framework that other modules depend on. The configuration appropriately reflects this dependency hierarchy.

Recommendation: Consider documenting in the sourcery.yml file why the imports differ from sibling projects (e.g., "BitwardenKit is a foundational framework with minimal dependencies"). This would help future maintainers understand the intentional difference.

Finding 2: Generated mocks directory structure could benefit from documentation (💭)

The PR adds BitwardenKit/Sourcery/Generated/.gitignore to exclude generated Swift files from version control. While this follows the existing pattern, the build configuration in project-bwk.yml:169-170 includes the generated file as optional:

- path: BitwardenKit/Sourcery/Generated/AutoMockable.generated.swift
  optional: true

Question: Is there a reason the generated mock file is marked as optional: true rather than being a required build input? This differs from how the file is treated in the output files specification (project-bwk.yml:155-156), where it's listed as a build output but not marked optional.

Observation: The optional: true marking appears intentional to allow builds to succeed even if Sourcery hasn't run yet (e.g., fresh checkout), but this should be verified.

Good Practices Observed

• ✅ Follows established Sourcery patterns from BitwardenShared and AuthenticatorShared
• ✅ Properly configures build phase with basedOnDependencyAnalysis: false to ensure Sourcery runs every build
• ✅ Correctly specifies output file location for Xcode's dependency tracking
• ✅ Uses .gitignore to exclude generated files from version control
• ✅ Updates test to import from BitwardenKitMocks instead of using manual mock
• ✅ Maintains consistent file structure with sibling projects
• ✅ The manual mock deletion demonstrates proper migration to auto-generated mocks

Action Items

1. [Optional] Add a comment to BitwardenKit/Sourcery/sourcery.yml explaining the minimal import configuration
2. [Optional] Verify CI passes to ensure Sourcery integration works correctly in CI environment
3. [Verification] Confirm that the optional: true marking for the generated mock file is intentional and appropriate for the build workflow

Technical Notes

Architecture Compliance: ✅ This change aligns with the project's testing architecture (see Docs/Testing.md:389-394), which explicitly mentions using Sourcery's AutoMockable annotation for mock generation.

Pattern Consistency: ✅ The implementation exactly mirrors the approach in BitwardenShared and AuthenticatorShared, demonstrating excellent consistency across the codebase.

Security Considerations: ✅ No security implications—this is a testing infrastructure change only.

Overall Assessment: This is a clean, well-executed PR that properly sets up Sourcery for BitwardenKit following established patterns. The findings above are minor improvement suggestions rather than blocking issues. The code is ready for merge pending CI verification.
