I'm using simpleTest to write my PHP tests. I'm writing a file upload plugin and was wondering how I may be testing it.
I would like to check that the file is correctly uploaded, in the right folder, that error are correctly returned when needed, etc.
How do I emulate a file upload (through the $_FILES variable) ? Are there any issues I should be aware of ?
I've found an alternate solution. I've spoofed the $_FILES array with test data, created dummy test files in the tmp/ folder (the folder is irrelevant, but I tried to stick with the default).
The problem was that is_uploaded_file and move_uploaded_file could not work with this spoofed items, because they are not really uploaded through POST.
First thing I did was to wrap those functions inside my own moveUploadedFile and isUploadedFile in my plugin so I can mock them and change their return value.
The last thing was to extends the class when testing it and overwriting moveUploadedFile to use rename instead of move_uploaded_file and isUploadedFile to use file_exists instead of is_uploaded_file.
