This sub-tree houses bzlmod test-modules for the rules_nixpkgs component modules as recommended by the Bazel Central Registry.

NOTE, the rules_go tests are split into separate workspace mode and bzlmod mode tests. Please keep these two test cases in sync.

The reason is that the Bazel module rules_go refers to itself as @rules_go, while the Bazel workspace for rules_go refers to itself as @io_bazel_rules_go. In principle, Bazel offers to remap workspace names. However, this would turn either the workspace or the bzlmod case into a very unusual use-case of rules_go, and would diminish the value of the test-case, as it would be not cover how users would use rules_go in either workspace or bzlmod mode.
