DEPRECATED! build a test package and run on target.
usage: fx run-test PKG_TARGET [runtests flags] This command is being deprecated in favor of `fx test`. Read more at: https://fuchsia.dev/fuchsia-src/development/testing/running_tests_as_components#converting_from_run-test_or_run-host-tests Builds the update package group, updates the device as necessary, and then executes the test as specified by [runtests flags] (or all tests in PKG_TARGET if no flags are given). Arguments: PKG_TARGET A package name as appears in `fx list-packages` All later arguments are passed directly to `runtests`, see `fx run-test -h` for all flags. Known Bugs: fxbug.dev/22526: After run-test, performing a pave without executing 'fx build' results in "appmgr not started after 20s", as this command only builds new packages, it avoids creating new paver artifacts, as such, a pave without a fresh build produces a system with inconsistent state.
