Task should fail if the status checks don't pass

[alexec]

Consider this synthetic task:

  download-ui-dependencies:
    cmds:
      - yarn
    status:
      - test -d node_modules

This task should only be successful if the status checks pass. I end up doing this:

  download-ui-dependencies:
    cmds:
      - yarn
      - test -d node_modules
    status:
      - test -d node_modules

Would it be good to run the status checks after the task runs so we fail fast?

@alexec don't you want preconditions?

Status is something slightly different, in-so-much that status means run or skip (so that a task only runs if status conditions are (not) satisfied.

@alexec , @trulede is right

status won't run the task if status conditions are not satified and it won't exit in error.

  download-ui-dependencies:
    cmds:
      - yarn
    status:
      - test -d node_modules

It'll run yarn if node_modules folder does not exist. If the folder exists, the task won't be ran

If you want to fail (IE: exit in error), you need to use preconditions :

  download-ui-dependencies:
    cmds:
      - yarn
    preconditions:
      - test -d node_modules
