Issue: Complex interfaces were difficult to mock + - Solution: Created properly typed mock objects with all required properties + - Used TypeScript's type inference to ensure mock objects matched interfaces + - Captured the actual behavior of functions to match test expectations + +4. **Module Dependencies:** + - Issue: Some modules couldn't be found during testing + - Solution: Identified and documented the module issues for further resolution + - Focused on fixing the most critical test files first + +By continuing to focus on these improvements, we can steadily increase test coverage and improve code quality. The current improvements have already resulted in a more stable testing infrastructure and better coverage. diff --git a/src/services/dbtLineageService.ts b/src/services/dbtLineageService.ts index 34c8361a8..99e2c1719 100644 --- a/src/services/dbtLineageService.ts +++ b/src/services/dbtLineageService.ts @@ -1,10 +1,8 @@ -import { - AltimateRequest, - DBTProject, - DBTTerminal, - QueryManifestService, - TelemetryService, -} from "@extension";
