I don't know if they integrate with

system_tools

etc. yet... So, another option might be an

adhoc_tool

that runs

npm test

and then a

experimental_test_shell_command

"test" that depends on the "output" of that

adhoc_tool

. I think the test can do nothing, it just needs to exist as a hack to ensure there's dependencies that trigger the

npm test

"codegen" in the

pants test

goal

experimental_test_shell_command does work though
