Within the tests/ folder, run.sh builds a docker image and runs the tests. Solutions are expected to be in a tests/student folder. For each available solution file, the appropriate test will be launched individually. The docker daemon or docker desktop needs to be running.
cd tests
./run.shThe final output should be similar to:
artists-do-work ✅ 4, basic-swap ✅ 4, basic-wallet ✅ 0, buy-tickets ✅ 2, check-document ✅ 6, connect-to-metamask ✅ 5, donation ✅ 6, eventful-token ✅ 3, fun-and-profit ✅ 3,
tests ran:9 in avg 4261 msIt is also possible to run tests individually (with debug mode on):
./run.sh retrieve-block-date The following underlying commands can be launched individually from tests/ folder:
# build the docker image
docker build . -t blockchain
# Run a BTC test
docker run --read-only --network none --memory 500M --user 1000:1000 -e DEBUG=true -e EXERCISE=retrieve-block-date --env HOME=/jail --env TMPDIR=/jail --workdir /jail --tmpfs /jail:size=100M,noatime,exec,nodev,nosuid,uid=1000,gid=1000,nr_inodes=5k,mode=1700 --volume $PWD/student.all:/jail/student:ro blockchain:latest
