### build and run tests on host

## Usage: fx run-host-tests [-z] [host test names ...] [-- [test runner 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#running_tests\n
##
## Builds and runs the given host tests.
## With "-z" passed, only Zircon tests will be run - and
## without it only tests from Garnet and above.
## Test runner flags can typically be --gtest_filter=TestSuiteName.TestName
## to restrict to a particular test or set of tests.
