[smolkaj]

What version of gRPC and what language are you using?

v1.49.1, C++

What operating system (Linux, Windows,...) and version?

Linux

What runtime / compiler are you using (e.g. python version or version of gcc)

LLVM / gcc with Bazel

What did you do?

Depend on the target @com_github_grpc_grpc//:grpc++_test in my BUILD.bazel file, see screenshot.

What did you expect to see?

For things to compile.

What did you see instead?

The following error message:

ERROR: /home/runner/work/pins-infra/pins-infra/p4_pdpi/BUILD.bazel:312:11: in cc_library rule //p4_pdpi:p4_runtime_session_mocking: target '@com_github_grpc_grpc//:grpc++_test' is not visible from target '//p4_pdpi:p4_runtime_session_mocking'. Check the visibility declaration of the former target if you think the dependency is legitimate

Anything else we should know about your project / environment?

I am a Google SWE working on a project that is used both internally and in open source.

This issue seems to be similar to #20208 and #20369.

@jonathan-dilorenzo for visibility

There seems to be some discussion around this on #26641

Is there a suggested way to overcome the visibility issue?
