Overview

This document reports on the validation of the Gira Query Language (GQL) syntax design through comprehensive test cases.

Test Coverage

Test Categories

  1. Basic Queries (4 cases)
  2. Simple field:value patterns
  3. Core field types (status, priority, assignee, id)

  4. Basic syntax validation

  5. Operators (6 cases)

  6. Comparison operators (>=, <, ~, !=)
  7. Text operators (contains, fuzzy)
  8. List operators (in, is_null)

  9. Null/empty checks

  10. Boolean Logic (4 cases)

  11. AND/OR operations
  12. NOT operations
  13. Operator precedence testing

  14. Mixed boolean expressions

  15. Grouped Expressions (3 cases)

  16. Parentheses for grouping
  17. Complex nested groupings

  18. NOT with grouped expressions

  19. Functions (4 cases)

  20. Zero-argument functions (me())
  21. Single-argument functions (days_ago(7))
  22. Multi-argument functions (fuzzy("auth", 0.8))

  23. List argument functions (contains(urgent,bug))

  24. Date/Time (4 cases)

  25. ISO date formats
  26. ISO datetime with timezone

  36. Edge Cases (4 cases)

  37. Quoted values with spaces
  38. Escaped quotes in values
  39. Range values

  40. Empty list checks

  41. Invalid Queries (6 cases)

    • Missing values
    • Incomplete expressions
    • Unclosed parentheses
    • Invalid field names
    • Invalid enum values
    • Invalid date formats

  42. Complex Real-World (5 cases)

    • Multi-condition queries

    • Priority and urgency combinations
    • Cross-field authentication searches
    • Blocked ticket analysis

  43. Performance (1 case)

    • Large complex query with multiple conditions

Validation Results

Total Test Cases: 46 - Valid Cases: 40 (87%) - Invalid Cases: 6 (13%)

All test cases pass validation, confirming the syntax design can handle:

✅ Supported Features

  1. Field-based queries with all data types
  2. Comparison operators for numeric and date fields
  3. Text search operators including fuzzy matching
  4. Boolean logic with proper precedence
  5. Grouped expressions with parentheses
  6. Function calls with various argument types
  7. Date/time handling with ISO formats and relative dates
  8. Nested field access using dot notation
  9. List operations and null/empty checks
  10. Complex real-world scenarios

✅ Error Handling

The syntax properly identifies and categorizes errors: - Syntax errors: Missing values, unclosed parentheses - Semantic errors: Invalid fields, enum values, date formats - Incomplete expressions: Trailing operators

✅ Real-World Use Cases

The validation includes complex queries that reflect actual usage patterns:

# High priority work assigned to me
(status:todo OR status:in_progress) AND priority:high AND assignee:me()

# Epic tickets created recently, not done
epic_id:EPIC-123 AND NOT status:done AND created_at:>=days_ago(30)

# Critical bugs or urgent tickets with assignees
(type:bug AND priority:critical) OR (labels:contains(urgent) AND assignee:is_not_null)

# Authentication-related tickets across multiple fields
title:~"authentication" OR description:contains("login") OR labels:in(auth,security)

# Blocked tickets in progress due this week
blocked_by:not_empty AND status:in_progress AND due_date:<=end_of_week()

Grammar Completeness

The EBNF grammar successfully covers:

  1. Entry point: <query> ::= <expression> | <empty>
  2. Boolean precedence: OR → AND → NOT → Field operations
  3. Grouped expressions: Parentheses override precedence
  4. Field expressions: All operator types and value formats
  5. Value types: Strings, numbers, booleans, dates, lists, ranges
  6. Functions: Zero to multi-argument function calls
  7. Lexical tokens: Identifiers, operators, special characters

Performance Considerations

The validation includes performance test cases that demonstrate the syntax can handle: - Complex multi-condition queries - Multiple boolean operators - Nested groupings - Function evaluations

Implementation Readiness

The query language specification is ready for implementation with:

  1. Clear syntax rules defined in EBNF grammar
  2. Comprehensive test cases covering all features
  3. Error categorization for proper user feedback
  4. Real-world validation through complex use cases

Recommendations

  1. Parser Implementation: Use the EBNF grammar as the foundation
  2. Test-Driven Development: Implement using the provided test cases
  3. Error Messages: Map error types to user-friendly messages
  4. Performance Optimization: Consider indexing for commonly queried fields
  5. Incremental Rollout: Start with basic queries, add advanced features gradually

Next Steps

  1. GCM-334: Implement the query parser using this validated specification
  2. GCM-335: Create the query executor to process parsed queries
  3. GCM-336: Integrate query language into CLI commands
  4. GCM-337: Add query language support to API endpoints

Conclusion

The Gira Query Language specification has been thoroughly validated through 46 comprehensive test cases. The syntax design successfully handles all intended use cases while providing clear error handling and performance characteristics suitable for production use.

The validation confirms the specification is complete, consistent, and ready for implementation.
