It's recommended to install cargo-odra first.

Install wasm-opt tool (it is needed for building contracts)

$ cargo install wasm-opt --locked

if you run casper node localy (nctl), you need to copy files to have access to the accounts keys from the host

$ docker run --rm -it --name mynctl -d -p 11101:11101 -p 14101:14101 -p 18101:18101 makesoftware/casper-nctl

$ docker cp mynctl:/home/casper/casper-node/utils/nctl/assets/net-1 .

Copy example env file and make appropriate adjustments (default values work with nctl)

$ cp .env.example .env

$ cargo odra build

To build a wasm file, you need to pass the -b parameter. The result files will be placed in ${project-root}/wasm directory.

$ cargo odra build -b casper

$ cargo run -p casper-name-cli deploy

To run test on your local machine, you can basically execute the command:

$ cargo odra test

To test actual wasm files against a backend, you need to specify the backend passing -b argument to cargo-odra.

$ cargo odra test -b casper
