In order to run hive tests on edited code (so not the latest remote master branch), see how to install hive. Now, in order to run EthereumJS, in the newly cloned hive folder, go to clients/ethereumjs and git clone git@github.com:ethereumjs/ethereumjs-monorepo.git there. It is not possible (due to how Docker works) to use a symlink to the monorepo. To use the local code in the just cloned directory, ensure that inside the ethereumjs client folder, you have moved the original Dockerfile (using this, always the remote master branch is used) and moved Dockerfile.local to Dockerfile.
One can now run hive tests. Example commands:
./hive --client ethereumjs --sim ethereum/engine --sim.parallelism 16 --sim.limit="engine-cancun"
Above command runs the ethereum/engine simulator, and only runs simulators which match engine-cancun. These are the engine-api tests for the cancun update. --sim.parallelism 16 signals that 16 parallel processes should be used.
After running the test suite, it is handy to use hiveview in order to visualize the results. The terminal output will note in the end how much tests have passed/failed, but it is obviously handy to inspect the failing tests to see what is wrong and debug those. To use hiveview, go to the root folder of the hive monorepo and follow these instructions.
./hive --client ethereumjs --sim ethereum/engine --sim.limit="engine-cancun/Invalid Missing Ancestor Syncing ReOrg, StateRoot, EmptyTxs=True, CanonicalReOrg=True, Invalid P9" --docker.output
This command runs a specific test, namely Invalid Missing Ancestor Syncing ReOrg, StateRoot, EmptyTxs=True, CanonicalReOrg=True, Invalid P9. The --docker.output command will log all output from both the simulator and the EthereumJS client to the terminal.
When changing code in the cloned monorepo, it is noted that re-running hive is rather slow. In order to make this faster, see this PR. The state of the PR should be leading, but in order for it to work, ensure that .dockerignore, Dockerfile and ethereumjs.sh are copied into the clients/ethereumjs folder of the hive repo.
This runner will use tsx (better debug output!) and is taking advantage of Docker's caching mechanism in order to ensure that any changes of code will get imported on a fresh start of a hive run fast.
