### build and run tests on host

##
## Usage: fx run-host-tests [-z] [host test names ...] [-- [test runner flags]]
## 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.
## If no host test names are provided, then all available
## host tests will be run.
## Test runner flags can typically be --gtest_filter=TestSuiteName.TestName
## to restrict to a particular test or set of tests.
