Test Framework Layers
  • Decision Tables Layer: Stores decision tables as CSV or Excel files defining conditions and expected actions.
  • Parser Layer: Reads and interprets decision tables into test cases programmatically.
  • Test Executor Layer: Runs tests based on parsed decision table data, driving the application or system under test.
  • Test Scripts Layer: Contains test scripts that call the executor with specific decision tables for different features.
  • Utilities Layer: Helper functions for data handling, logging, and assertion support.
  • Configuration Layer: Holds environment settings, test parameters, and credentials.
  • Reporting Layer: Generates readable test reports showing which decision table rules passed or failed.
Configuration Patterns

Use a config.yaml file to manage:

  • Test environment URLs (dev, staging, production)
  • Browser or platform settings if UI tests are involved
  • Credentials or API keys (stored securely, not in code)
  • Paths to decision table files

Load configuration at test start to keep tests flexible and environment-independent.

Test Reporting and CI/CD Integration
  • Generate HTML or XML reports summarizing which decision table rules passed or failed.
  • Include detailed logs showing input conditions and expected vs actual outcomes for each rule.
  • Integrate with CI/CD pipelines (e.g., Jenkins, GitHub Actions) to run decision table tests automatically on code changes.
  • Fail builds if critical decision table rules fail, ensuring quality gates.
Best Practices for Decision Table Testing Framework
  • Keep decision tables clear and simple: Use concise condition and action descriptions for easy understanding.
  • Automate parsing: Write reusable code to convert decision tables into test cases automatically.
  • Separate data from code: Store decision tables outside test scripts to allow easy updates without code changes.
  • Use descriptive test reports: Show which rules passed or failed with clear input and output details.
  • Maintain traceability: Link decision table rules to requirements or user stories for coverage tracking.
Self Check Question

Where in this framework structure would you add a new decision table for testing the password reset feature?

Key Result
Organize decision tables as external data files parsed by reusable code to drive automated tests with clear reporting.
