The Ultimate Guide To Testing Uploads and Downloads in Laravel
Laravel provides some helpful documentation for testing that your file uploads and downloads work as expected. But their examples test at a shallow level, in the name of test performance and simplicity. The documented upload tests upload no real content; the download tests only check headers or check for the presence of strings. Thorough testing often requires testing at a deeper level - ensuring the file is parsed properly by your backend, or that you are generating a valid file at all. This guide covers most of those common use cases. Note that Pest is used for the examples here, but the approaches should work just as well for PHPUnit.
