Type of Change

• Bug fix
• Feature
• Other (Code Refactoring)

---

Current Behavior

The previous implementation duplicated logic across two commands:

• saveBlankUnitTest
• createUnitTest

This duplication made the code harder to maintain, with redundant calls to shared utilities like:

• getWorkflowNode
• promptForUnitTestName
• processAndWriteMockableOperations

---

New Behavior

• Consolidated shared logic between saveBlankUnitTest and createUnitTest to improve maintainability.
• Introduced helper methods for:
  • Parsing and transforming unitTestDefinition outputs (parseUnitTestOutputs).
  • Processing mockable operations (processAndWriteMockableOperations).
  • Generating C# class definitions dynamically (generateCSharpClasses).
• Updated the structure to use consistent workflows and error handling via callWithTelemetryAndErrorHandling.

Highlights:

• Improved maintainability and reduced code duplication.
• Added enhanced telemetry logging for better debugging and monitoring.
• Maintained current functionality without introducing breaking changes.

---

Impact of Change

• This is a breaking change.

No breaking changes were introduced. Existing commands and workflows retain their behavior but benefit from shared logic and improved error handling.

• [nitpick] The function name 'generateUnitTestFromRun' is ambiguous. It should be renamed to 'generateUnitTestFromRunId' for clarity.

• The error handling for the API call response is missing. Detailed error handling should be added to handle different error scenarios.

const response = await axios.post(apiUrl, unitTestGenerationInput, {

• [nitpick] The localized message for adding the tests directory to the workspace could be more descriptive.

await ensureDirectoryInWorkspace(paths.testsDirectory);

• The error handling logic in the 'generateUnitTestFromRun' function is not covered by tests. Add test cases to verify the error handling scenarios.

• [nitpick] The regular expression for runId validation might be too restrictive. Consider allowing lowercase letters if applicable.

const runIdFormat = /^[A-Z0-9]+$/;
