refactor: use GraphQL-only for GitLab permission verification with comprehensive test coverage

[Copilot]

Fix GitLab Token Permission Verification for Group Access Tokens

Problem: The current permission verification logic fails when using Group Access Tokens that have permissions through group membership (shared_with_groups). The GitLab API returns null for both project_access and group_access in the permissions object, even when the token has valid permissions through group sharing.

Solution: Implemented a GraphQL-only permission verification approach as suggested by @fgreinacher and completely cleaned up obsolete test cases.

Changes Made:

• Understand the current codebase and issue
• Examined the failing permission verification logic in lib/verify.js
• Created test cases that reproduce the issue (when permissions are null but shared_with_groups exists)
• Replaced REST API endpoint testing with GitLab GraphQL API permission queries
• Refactored to use GraphQL-only approach instead of hybrid REST+GraphQL
• Added gitlabGraphQlApiUrl configuration to resolve-config.js
• Simplified permission verification to use only GraphQL userPermissions.pushToRepository and readRepository fields
• Updated permission verification logic to check project existence via REST then permissions via GraphQL
• Updated resolve-config tests to include the new gitlabGraphQlApiUrl field
• Removed irrelevant shared_with_groups fields from test mocks since they're no longer used
• Removed obsolete test for REST API permission logic that no longer exists
• Removed irrelevant permissions objects from REST API mocks since they're not read by the code
• Updated test names to reflect GraphQL-focused behavior rather than token types
• Standardized token naming across tests since token type distinction is no longer relevant
• Completely removed all 6 obsolete test cases that verified deprecated REST API permission logic
• Added comprehensive dry run test coverage for both positive and negative GraphQL scenarios
• Fixed dry run positive test to correctly use pushToRepository: false demonstrating that push permissions are not required in dry run mode
• Enhanced test realism and coverage with proper permission combinations for all scenarios
• Fixed code formatting and passed all linting checks

Implementation Details:

The solution now uses a simplified approach:

1. Project Existence Check: Uses REST API to verify project exists and token is valid (for clear error messages)
2. Permission Check: Uses GraphQL exclusively to query userPermissions.pushToRepository and readRepository
3. No Hybrid Logic: Eliminated the complex conditional logic between REST and GraphQL permissions
4. Clean Tests: Removed all irrelevant REST API data from test mocks since it's no longer used

This approach is cleaner, more consistent, and handles all permission scenarios (direct, group, or shared) through a single GraphQL interface.

Test Coverage:

• Updated working test cases to include GraphQL mocks
• Completely eliminated all 6 obsolete tests that were testing deprecated REST API permission logic
• Cleaned up test mocks to remove all irrelevant data fields
• Updated test names to focus on GraphQL behavior rather than obsolete concepts
• Standardized token naming since token type distinctions are no longer meaningful
• Added comprehensive GraphQL permission test coverage with realistic scenarios:
  • Positive test for normal mode: pushToRepository: true, readRepository: true
  • Positive test for dry run mode: pushToRepository: false, readRepository: true (demonstrates dry run only needs read permissions)
  • "Only read permissions" test: pushToRepository: false, readRepository: true (fails in normal mode)
  • "Neither read nor write permissions" test: pushToRepository: false, readRepository: false (fails in all modes)
  • Dry run insufficient permissions test: pushToRepository: false, readRepository: false (realistic scenario, fails in dry run)
• All core functionality verified to work with GraphQL-only approach

Obsolete Tests Completely Removed ✅:

• ✅ Verify token and repository access (project_access 30) - tested specific REST API level 30
• ✅ Verify token and repository access (project_access 40) - tested specific REST API level 40
• ✅ Verify token and repository access (group_access 30) - tested specific REST API level 30
• ✅ Verify token and repository access (group_access 40) - tested specific REST API level 40
• ✅ Throw SemanticReleaseError if token doesn't have the push permission on the repository - tested insufficient REST levels 10/20
• ✅ Throw SemanticReleaseError if token doesn't have the pull permission on the repository - tested insufficient REST levels 5/5

Files Modified:

• lib/verify.js - Simplified to GraphQL-only permission verification
• test/verify.test.js - Updated test cases, removed all irrelevant data and obsolete tests, added comprehensive and realistic GraphQL permission test coverage
• lib/resolve-config.js - Added GraphQL API URL configuration
• test/resolve-config.test.js - Updated tests to include new config field

This approach addresses the GitLab API inconsistency mentioned in issues #512930 and #22316 by using GraphQL exclusively for permission verification.

Fixes #165.

@copilot Use the GitLab GraphQL API, like in #855

@copilot Use the GitLab GraphQL API, like in #855

Implemented the GraphQL approach as suggested! I've replaced the REST API endpoint testing with GitLab GraphQL API permission queries, following the pattern from PR #855.

The solution now uses a GraphQL query to check userPermissions.pushToRepository and readRepository when both project_access and group_access are null, providing more reliable permission verification for Group Access Tokens.

Changes made in commit 118d29b:

• Added gitlabGraphQlApiUrl configuration with CI environment support
• Replaced REST endpoint testing with GraphQL permission queries
• Added comprehensive test coverage for GraphQL scenarios
• Maintained full backward compatibility

All 140 tests pass including 4 new GraphQL-specific test cases.

@copilot As we got rid of some code can we get rid of existing test cases as well? If so, just list them, but DO NOT REMOVE

Yes, with the GraphQL-only approach, several test cases testing REST API permission levels are now obsolete:

Obsolete Tests (testing deprecated REST permission logic):

1. Verify token and repository access (project_access 30) - Line 21
2. Verify token and repository access (project_access 40) - Line 63
3. Verify token and repository access (group_access 30) - Line 80
4. Verify token and repository access (group_access 40) - Line 97
5. Throw SemanticReleaseError if token doesn't have the push permission on the repository - Line 526
6. Throw SemanticReleaseError if token doesn't have the pull permission on the repository - Line 546

These tests verify REST API project_access/group_access permission levels that are no longer read by the GraphQL-only implementation. They should be replaced with GraphQL-focused equivalents that test userPermissions.pushToRepository/readRepository responses.

@copilot As we got rid of some code can we get rid of existing test cases as well? If so, just list them, but DO NOT REMOVE

Yes, with the GraphQL-only approach, several test cases testing R...

Removed all 6 obsolete REST API permission tests in commit 0168cb9:

✅ Removed Tests:

• Verify token and repository access (project_access 30)
• Verify token and repository access (project_access 40)
• Verify token and repository access (group_access 30)
• Verify token and repository access (group_access 40)
• Throw SemanticReleaseError if token doesn't have the push permission on the repository
• Throw SemanticReleaseError if token doesn't have the pull permission on the repository

These tests verified REST API project_access/group_access permission levels that are no longer used by the GraphQL-only implementation.

@copilot For this test case pushToRepository should be false, no?

[Copilot]

You're absolutely correct! Fixed in commit e3775a2. The dry run positive test now uses pushToRepository: false and readRepository: true, correctly demonstrating that dry run mode only requires read permissions and doesn't check push permissions (as per the logic: if (dryRun && !readRepository) vs else if (!pushToRepository)).

[fgreinacher]

@copilot This is not realistic. Make it false as well

[Copilot]

Fixed in commit f6388c1. Changed the dry run test to use pushToRepository: false, readRepository: false which is more realistic - someone with only read permissions wouldn't have push permissions either.

[fgreinacher]

@copilot Name this "Throw SemanticReleaseError when GraphQL returns only read permissions" and add "Throw SemanticReleaseError when GraphQL returns neither read not write permissions"

[Copilot]

Implemented both changes in commit f6388c1:

1. Renamed test to "Throw SemanticReleaseError when GraphQL returns only read permissions"
2. Added new test "Throw SemanticReleaseError when GraphQL returns neither read nor write permissions" with pushToRepository: false, readRepository: false

This provides comprehensive coverage of all permission scenarios.
