Can we add a test that enters this if clause?

🛠️ Refactor suggestion

Ensure the test invocation covers the function call.

Your test awaits writeToFile but doesn't explicitly invoke it with parameters. Clarify whether this is intentional. If your intention is to test calling writeToFile() without arguments, adjust the test as follows to ensure it actually attempts a call:

- await expect(writeToFile).rejects.toThrow();
+ await expect(writeToFile()).rejects.toThrow();

Also, remove extra blank lines for compliance with the style guide.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

await expect(writeToFile).rejects.toThrow();
