# https://go.dev/issue/51723: 'go test' should not stamp VCS metadata
# in the build settings. (It isn't worth the latency hit, given that
# test binaries are almost never distributed to users.)

exec git init
# The test binaries should not have VCS settings stamped.
# (The test itself verifies that.)
go test . ./testonly
# Remove 'git' from $PATH. The test should still build.
# This ensures that we aren't loading VCS metadata that
# we subsequently throw away.

# Compiling the test should not require the VCS tool.

# When listing a main package, in general we need its VCS metadata to determine
# the .Stale and .StaleReason fields.

# Adding the -test flag should be strictly additive — it should not suppress the error.
