+Custom nogo analyzers
+=====================
+
+.. _nogo: /go/nogo.rst
+.. _go_library: /docs/go/core/rules.md#_go_library
+
+Tests to ensure that custom `nogo`_ analyzers run and detect errors.
+
+.. contents::
+
+custom_test
+-----------
+Verifies that custom analyzers print errors and fail a `go_library`_ build when
+a configuration file is not provided, and that analyzers with the same package
+name do not conflict. Also checks that custom analyzers can be configured to
+apply only to certain file paths using a custom configuration file.

+Verifies that a simple custom analyzer's behavior can be modified by setting
