Frequently Asked Questions
What files should every test suite include?
At minimum: small and large files in each accepted format, an empty file, a file slightly above your size limit, a file with wrong MIME type, and a corrupt file for each format you accept.
How many file sizes should I test?
Test at least 3 sizes: well under the limit, near the limit, and over the limit. For UI testing, also include very small files (< 1KB) to test edge cases.
