Test Implementation Summary

Overview

Started implementing comprehensive test coverage for the Bloomreach CMS Document Export Plugin. This document tracks the test implementation progress, test cases created, and the testing roadmap.

Test Results (Phase 1)

Tests Implemented: 28 ✅

1. Utility Tests (21 tests)

ExportJsonUtilsTest (7 tests)

  • ✅ testExtractHandleWithNullNode - Null input handling
  • ✅ testExtractHandleWithHandleNode - Returns same node if already handle
  • ✅ testExtractHandleWithDocumentNodeWhoseParentIsHandle - Returns parent handle
  • ✅ testExtractHandleWithNodeWhoseParentIsNotHandle - Returns null for non-handle parent
  • ✅ testExtractHandleWithNodeHavingNullParent - Handles null parent gracefully
  • ✅ testExtractHandleHandlesRepositoryException - Propagates RepositoryException
  • ✅ testExtractHandleHandlesRepositoryExceptionOnParentCheck - Exception propagation on parent access

ExportTabularUtilsTest (14 tests)

  • ✅ testPropertyValueToStringSingleValue - Single-valued property conversion
  • ✅ testPropertyValueToStringMultipleValues - Multi-valued property with pipe delimiter
  • ✅ testPropertyValueToStringMultipleValuesWithEmptyStrings - Preserves empty strings
  • ✅ testPropertyValueToStringMultipleValuesWithSpecialCharacters - Preserves special chars
  • ✅ testPropertyValueToStringMultipleValuesWithExceptionInValue - Graceful error handling in arrays
  • ✅ testPropertyValueToStringEmptyMultipleValues - Empty arrays
  • ✅ testGetPropertyTypeNameString - Returns 'String' for PropertyType.STRING
  • ✅ testGetPropertyTypeNameLong - Returns 'Long'
  • ✅ testGetPropertyTypeNameDouble - Returns 'Double'
  • ✅ testGetPropertyTypeNameBoolean - Returns 'Boolean'
  • ✅ testGetPropertyTypeNameDate - Returns 'Date'
  • ✅ testGetPropertyTypeNameBinary - Returns 'Binary'
  • ✅ testGetPropertyTypeNameReference - Returns 'Reference'
  • ✅ testGetPropertyTypeNameUndefined - Returns 'undefined' (lowercase)

2. Workflow Tests (7 tests)

ExportJsonWorkflowImplTest (7 tests)

  • ✅ testExportJsonDocumentBasicInfo - Document path, name, primary type
  • ✅ testExportJsonDocumentWithSingleValuedProperty - Single-valued property serialization
  • ✅ testExportJsonDocumentWithMultiValuedProperty - Array property serialization
  • ✅ testExportJsonDocumentWithMetadata - Metadata extraction (created, modified, author)
  • ✅ testExportJsonDocumentHandlesUnserializableProperty - Error resilience for unparseable properties
  • ✅ testExportJsonDocumentThrowsForInvalidNodeId - RepositoryException propagation for missing nodes
  • ✅ testInvokeWorkflowIsNoOp - invokeWorkflow() no-op validation

Test Coverage by Component

Repository Layer (Backend Workflows)

Class Status Tests Coverage
ExportJsonUtils ✅ Covered 7 Handle extraction logic
ExportTabularUtils ✅ Covered 14 Property conversion, type names
ExportJsonWorkflowImpl ✅ Covered 7 Basic JSON export scenarios
ExportTabularWorkflowImpl ⏳ Pending - CSV/TSV export logic
ExportPdfWorkflowImpl ⏳ Pending - PDF/XSL-FO generation (complex)
ExportHtmlWorkflowImpl ⏳ Pending - HTML semantic generation
ExportXmlWorkflowImpl ⏳ Pending - XML serialization

CMS Frontend Layer (Dialogs & Pages)

Component Status Tests Coverage
ExportJsonPlugin ⏳ Pending - Plugin registration, workflow orchestration
Dialog Classes (5) ⏳ Pending - Form validation, parameter handling
Download Pages (5) ⏳ Pending - HTTP response generation

Test Architecture

Testing Framework

  • Unit Testing: JUnit 4
  • Mocking: EasyMock 4.x
  • JSON Validation: Jackson ObjectMapper
  • Build System: Maven Surefire

Testing Patterns Used

  1. Mock-based Testing: All JCR objects (Node, Session, Property, Value) mocked
  2. Reflection-based Context Injection: WorkflowContext injected via reflection for workflow testing
  3. Expected Exception Testing: assertThrows for error path validation
  4. Data Validation: JSON parsing to validate output structure

Roadmap

Phase 2: Workflow Tests (Estimated 20-25 tests)

  • ExportTabularWorkflowImpl - CSV/TSV generation
  • ExportPdfWorkflowImpl - XSL-FO to PDF conversion
  • ExportHtmlWorkflowImpl - Semantic HTML with CSS
  • ExportXmlWorkflowImpl - XML serialization with namespaces

Phase 3: Frontend Tests (Estimated 15-20 tests)

  • Dialog form validation and parameter extraction
  • HTTP response header generation
  • File download functionality
  • Session attribute storage/cleanup
  • Wicket component behavior

Phase 4: Integration Tests (Estimated 10-15 tests)

  • End-to-end export workflows
  • Multi-valued property handling across formats
  • Error recovery and user feedback
  • Large document handling

Phase 5: Error Handling & Edge Cases (Estimated 10-15 tests)

  • Missing/null properties
  • Binary and reference properties
  • Complex nested structures
  • Permission errors
  • Repository connection failures

Key Testing Insights

Coverage Priorities

  1. High Priority (Error-prone, high impact):

    • PDF export (FOP integration, complex XSL-FO generation)
    • Multi-valued property handling (across all formats)
    • HTTP response generation
    • Error recovery

  2. Medium Priority (Standard functionality):

    • Single export workflows
    • Metadata extraction
    • Form parameter validation
    • Basic file download

  3. Low Priority (Straightforward, low risk):

    • Utility methods (already tested)
    • Constants validation
    • Plugin initialization

Test Configuration

tests/pom.xml               - Maven dependencies and Surefire config
tests/src/test/resources/   - HCM test configuration and fixtures

Next Steps

  1. Implement Phase 2 (Workflow Tests for remaining export formats)
  2. Add code coverage reporting (JaCoCo integration)
  3. Create integration tests for end-to-end workflows
  4. Document test execution in CI/CD pipeline
  5. Add pre-commit hooks to run tests automatically

Notes

  • All utility tests passing with mocked dependencies
  • Workflow tests using reflection injection of WorkflowContext
  • Error handling tests validate exception propagation
  • JSON validation tests parse output and check structure
  • Special characters and edge cases covered in property value tests
