CNTRLPLANE-2272:Refactor tests-ext initialization to improve error handling

[wangke19]

Summary

This PR refactors the cluster-config-operator-tests-ext initialization code to improve error handling and follow Go best practices. The changes align with the pattern established in oauth-apiserver PR #162.

Changes

• Modified newOperatorTestCommand() to return (*cobra.Command, error) instead of *cobra.Command
• Modified prepareOperatorTestsRegistry() to return (*oteextension.Registry, error) instead of *oteextension.Registry
• Added proper error wrapping with context using fmt.Errorf("failed to prepare test registry: %w", err)
• Simplified main() function and removed unused context.Context parameter
• Replaced "context" import with "fmt" for error formatting

Benefits

• Better error handling: Errors are now properly propagated up the call stack with context
• More testable: Functions can now return errors instead of calling klog.Fatal() directly
• Maintainable: Follows established Go idioms and OpenShift patterns
• Consistent: Aligns with similar refactoring done in oauth-apiserver

Testing

• ✅ Build successful: make build
• ✅ Binary runs correctly: ./cluster-config-operator-tests-ext --help
• ✅ All OTE commands available (list, run-suite, run-test, etc.)

Walkthrough

This PR refactors error handling in the operator test command initialization. Two function signatures were updated to return errors: newOperatorTestCommand() and prepareOperatorTestsRegistry(). The main function now properly handles these errors alongside import adjustments.

Changes

Cohort / File(s)	Summary
Error handling improvements cmd/cluster-config-operator-tests-ext/main.go	Updated newOperatorTestCommand() signature to return (*cobra.Command, error) instead of (context.Context) *cobra.Command. Updated prepareOperatorTestsRegistry() signature to return (*oteextension.Registry, error) instead of *oteextension.Registry. Main function now handles errors from both functions with proper error propagation. Replaced context import with fmt.

11-11: LGTM!

The import change correctly adds fmt for error formatting and removes the unused context import.

---

24-32: LGTM!

The error handling in main() is correct and follows Go best practices for CLI applications. The function properly checks for initialization errors and uses klog.Fatal appropriately at the application entry point.

---

34-60: LGTM!

The refactored function signature and error handling are correct:

• Properly propagates errors from prepareOperatorTestsRegistry() with descriptive context wrapping
• Returns errors instead of calling klog.Fatal() internally, improving testability
• The use of klog.Fatal() in the command's Run function (line 46) is acceptable as it's a command handler

---

67-73: LGTM!

The signature change to return an error is correct and aligns with the PR's goal of improving error handling patterns. While the function currently always returns nil for the error, this design:

• Maintains consistency with the error-returning pattern
• Improves testability by allowing error injection in tests
• Prepares for future error conditions without requiring signature changes
