6# Environment variables that control run.bash:
7#
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.
