generate test main

[GinFungYJF]

When I use bazel to build my go_test, it shows the error:

ERROR: /root/testgo/hsa-service-center/src/servicecenter/controllers/BUILD:35:1: null failed: linux-sandbox failed: error executing command /root/.cache/bazel/_bazel_root/40633db3e907142ca23269a67b71fa41/execroot/src/_bin/linux-sandbox ... (remaining 3 argument(s) skipped). bazel-out/local-fastbuild/bin/servicecenter/controllers/instance_watcher_main_test.go:7: imported and not used: "servicecenter/controllers/instance_watcher" as undertest Target //servicecenter/controllers:instance_watcher failed to build

but when I delete the line https://github.com/bazelbuild/rules_go/blob/master/go/tools/generate_test_main.go#L95 ,
it works. Is it a bug?

Not a bug, but it looks like if !HasTestMain && len(Names) == 0 then the
package undertest is not used.
But that is a useless test -- if there is no TestMain being called, and no
Test* functions, then nothing will happen.
If anything is missing, it is that we don't have something that errros out
if the above condition is true just before the "tmp :=" line you linked.
