16-23: Ensure tests run independently for parallel execution.
ThebeforeAllandafterAllhooks manage database connections at a suite level. If future parallelization is desired, consider setting up connections at the test level or providing separate environments. For this current design, it's acceptable as is.
25-33: Catch and log specific errors for easier debugging.
The try/catch block is helpful for handling import errors. For more detailed error diagnostics, you could log the error’sstdoutorstderr(if available) afterexecSync. This would assist in troubleshooting test failures.src/utilities/loadSampleData.ts (1)

31-46: Robust sample data listing function.
ThelistSampleDatafunction enumerates.jsonfiles in thesample_datadirectory and prints counts. This is a neat approach to ensure content is correct before insertion. For consistency, consider adding basic validation to detect empty or malformed JSON files.

1-2: Good practice using Vitest and DB utilities.
Great job initializing Vitest and importing database connect/disconnect utilities. This approach provides clear testing boundaries, ensuring each test suite starts with a fresh connection and properly tears down afterward.
34-42: Validation of model existence and document counts looks correct.
You correctly query each model to confirm that the expected documents were imported. This is a good approach for detecting incomplete or misconfigured sample data scenarios early.
44-53: Keep test data in sync with sample data changes.
When sample data changes, the expected document counts (like 15 users, 17280 events, etc.) must be updated. Consider dynamically reading the JSON files to derive counts, or keep an always-updated reference.
tsconfig.json (1)
12-14: Recognize Vitest types in TypeScript.
Adding "vitest" to the types array ensures type definitions are recognized during compilation, preventing type errors in new test files. This is beneficial for maintaining strict type-safety in tests.

3-3: Importing fileURLToPath is essential for ES module path manipulations.
Modernizing the codebase to use fileURLToPath helps with cross-platform compatibility and SSR use cases. This is a best practice for ES module–based projects.
20-20: Confirm the directory resolution logic.
Defining dirname with path.dirname(fileURLToPath(import.meta.url)) aligns the directory reference properly for ES modules. Verify that all references to dirname reflect the correct folder structure, especially if this script is called from different directories.
115-118: Path resolution updated for inserting collections.
Using path.resolve is safer than path.join, especially when dealing with ESM. Good job ensuring the correct file path in a cross-platform manner.

tests/utilities/loadSampleData.spec.ts (1)
44-53: Performance consideration for large sample data
Testing with very large data sets (e.g., 17,280 events) can affect test performance. If test runtimes become prolonged, consider creating a smaller sample for test purposes while preserving coverage.src/utilities/loadSampleData.ts (1)
115-115: Potential asynchronous race withprocess.exit(0)
Becauseprocess.exit(0)immediately terminates the Node.js process, there is a risk that outstanding asynchronous operations (like database writes) might not finish. If safe shutdown is required, consider an alternative approach (e.g., gracefully closing resources before exit).

1-2: Use consistent test naming convention
The test suite and test blocks follow a clear naming pattern. Ensure that all team members adhere to the same style in future tests (e.g., “Sample Data Import Tests” and “should …”).
25-29: Consider verifying command execution environment
Executing execSync("npm run import:sample-data -- --format") within the test may have side effects, depending on the test environment. Consider checking whether the environment is suitable (e.g., not production) or mocking this command in a purely unit-test scenario.
30-32: Ensure that errors are properly handled
The catch block logs the error and rethrows it. This is good, as it ensures the test fails appropriately. Make sure there are no circumstances in which partial data insertion could leave the database in an unexpected state.

3-3: Exporting fileURLToPath
The introduction of fileURLToPath is a robust way to handle ESM module paths across various platforms, including Windows. Good approach.
Line range hint 31-46: Improved resolution of sample data paths
Using path.resolve ensures that file paths are absolute and platform-agnostic, reducing path-related issues.
