Test _removeFile function in multer's custom storage engine #1293
Description
I went through the docs here: https://github.com/expressjs/multer/blob/master/StorageEngine.md
Here the logic of _handleFile is clear, but there's doubt about _removeFile function, like
- How will it get new parameters from file?
- If we save uploaded file name during _handleFile function, would it be possible to retrieve that in _removeFile?
- How to make _removeFile invoked and test all these using a console log there ?
