List of arbitrary text tags. Tags may be any valid string; default is the
empty list.
Tags can be used on any rule; but tags are most useful
on test and test_suite rules. Tags on non-test rules
are only useful to humans and/or external programs.
Tags are generally used to annotate a test's role in your debug
and release process. Typically, tags are most useful for C++ and
Python tests, which
lack any runtime annotation ability. The use of tags and size elements
gives flexibility in assembling suites of tests based around codebase
check-in policy.
A few tags have special meaning to the build tool, such as indicating that a particular test cannot be run remotely, for example. Consult the Bazel documentation for details.
