This is a collection of tests for the libwebp libraries, currently covering fuzzing through the APIs. Additional test vector coverage can be found at: https://chromium.googlesource.com/webm/libwebp-test-data
Building
Fuzzers
Follow the build instructions for libwebp, optionally adding build flags for various sanitizers (e.g., -fsanitize=address).
-DWEBP_BUILD_FUZZTEST=ON can then be used to compile the fuzzer targets:
$ cmake -B ./build -S . -DWEBP_BUILD_FUZZTEST=ON
$ make -C build
