There are a few potential solutions to the "TypeError: window.URL.createObjectURL is not a function" issue in Vitest mocking:
Check if the browser supports the createObjectURL() function: If the browser does not support the createObjectURL() function, there won't be any function called window.URL.createObjectURL. In such cases, you can try using other alternatives like the FileReader API or Blob URL.
Use a polyfill: You can use a polyfill like Blob.js or Blob-polyfill to add the missing functionality to the browser. The polyfill will make the createObjectURL() function available in all browsers regardless of whether they support the function natively or not.
Use a mock for the createObjectURL() function: You can create a mock for the createObjectURL() function and use it in your tests. This will simulate the functionality of the createObjectURL() function and help to resolve the error.
Update the code to use a different method: In the event that none of the above solutions work, you can update the code to use a different method that accomplishes the same task as createObjectURL(). This would require some modifications to the code, but it should help to resolve the error.
