Askama Fuzzing

First install cargo-fuzz and rust-nightly (once):

cargo install cargo-fuzz
rustup install nightly

Then execute in this folder:

RUST_BACKTRACE=1 nice cargo +nightly fuzz run <fuzz_target>

fuzz_target is one out of all, filters, html or parser.

The execution won't stop, but continue until you kill it with ctrl+c. Or until it finds a panic. If the execution found a panic, then a file with the input scenario is written, e.g. fuzz/artifacts/parser/crash-b91ab…. To get more information about the failed scenario, run or debug this command with the given path:

cargo run -- <fuzz_target> fuzz/artifacts/parser/crash-b91ab…
