$> cargo build --release -p data-avail
In development mode the node will run as a collator on a network which requires just one
collator to finalize blocks.
We also add --tmp, therefore the state will be deleted at the end of the process.
$> cargo run --release -p data-avail -- --dev --tmp
Finished release [optimized] target(s) in 0.41s
Running `target/release/data-avail --dev --tmp`

You can run any benchmark and generate the proper weight.rs file. In the following command, we are
running the benchmarks from da-control pallet, and the generated file is
$> cargo run --release -p data-avail --features runtime-benchmarks -- \
benchmark \
--chain=dev \
--steps=20 \
--repeat=30 \
--log=warn \
--execution=wasm \
--wasm-execution=compiled \

Here is the table of custom IDs for invalid transaction errors:
| Custom ID | Name | Description |

| 138 | ForbiddenAppId | The extrinsic is not available for the given AppId |
We are using grcov to aggregate code coverage information and generate reports.
To install grcov run
$> cargo install grcov
Source code coverage data is generated when running tests with
$> env RUSTFLAGS="-Zinstrument-coverage" \
SKIP_WASM_BUILD=true \
LLVM_PROFILE_FILE="tests-coverage-%p-%m.profraw" \
cargo test
To generate report, run
$> grcov . -s . \
--binary-path ./target/debug/ \
-t html \
--branch \
--ignore-not-existing -o \
./target/debug/coverage/
To clean up generate coverage information files, run
$> find . -name \*.profraw -type f -exec rm -f {} +
Open index.html from ./target/debug/coverage/ folder to review coverage data. Since WASM build is not possible yet, SKIP_WASM_BUILD is required when running tests.
