# Tests that the generated test main file has a generated code comment.
# This is needed by analyzers that access source files through 'go list'.
# Verifies golang.org/issue/31971.
# TODO(jayconrod): This test is brittle. We should write _testmain.go as
# a build action instead of with an ad-hoc WriteFile call
# in internal/test/test.go. Then we could just grep 'go get -n'.
