HOW-TO-TEST-BENCHMARK-PALLETS.md

Some useful info to debug and code a pallet

Run debug or a test of a pallet:

SKIP_WASM_BUILD=1 RUST_LOG=runtime=debug cargo test --package <INSERT_PALLET_NAME> -- --nocapture
//example:
SKIP_WASM_BUILD=1 RUST_LOG=runtime=debug cargo test --package pallet-sim-renault -- --nocapture

Run benchmark of a pallet:

cargo build --release --features runtime-benchmarks

./target/release/parachain-collator benchmark pallet --chain dev --pallet "pallet_sim_renault" --extrinsic "*" --repeat 1000 --output benchmark_sim_renault.rs
#or
cargo build --release --features runtime-benchmarks && ./target/release/parachain-collator benchmark pallet --chain=dev --pallet="pallet_sim_insurance" --extrinsic="*" --wasm-execution=compiled --execution=wasm --repeat=20 --steps=50 --template=./frame-weight-template.hbs --output=./pallets/sim_insurance/src/weights.rs
