     8  # GO_TEST_SHARDS: number of "dist test" test shards that the
     9  # $GOROOT/test directory will be sliced up into for parallel
    10  # execution. Defaults to 1, unless GO_BUILDER_NAME is also specified,
    11  # in which case it defaults to 10.
    12  #
    13  # GO_BUILDER_NAME: the name of the Go builder that's running the tests.
    14  # Some tests are conditionally enabled or disabled based on the builder
    15  # name or the builder name being non-empty.
    16  #
    17  # GO_TEST_SHORT: if set to a non-empty, false-ish string, run tests in "-short=false" mode.
    18  # This environment variable is an internal implementation detail between the
    19  # Go build system (x/build) and cmd/dist for the purpose of longtest builders,
    20  # and will be removed if it stops being needed. See go.dev/issue/12508.
    21  #
    22  # GO_TEST_TIMEOUT_SCALE: a non-negative integer factor to scale test timeout by.
    23  # Defaults to 1.
