+module StubMemberAccessLevel
+  # Stubs access level of a member of +object+.

+  # The following types are supported:
+  # * `Project` - stubs `project.team.max_member_access(user.id)`
+  # * `Group` - stubs `group.max_member_access_for_user(user)`
+  #
+  # @example
+  #
+  #   stub_member_access_level(project, maintainer: user)
+  #   project.team.max_member_access(user.id) # => Gitlab::Access::MAINTAINER
+  #
+  #   stub_member_access_level(group, developer: user)
+  #   group.max_member_access_for_user(user) # => Gitlab::Access::DEVELOPER
+  #
+  #   stub_member_access_level(project, reporter: user, guest: [guest1, guest2])
+  #   project.team.max_member_access(user.id) # => Gitlab::Access::REPORTER
+  #   project.team.max_member_access(guests.first.id) # => Gitlab::Access::GUEST
+  #   project.team.max_member_access(guests.last.id) # => Gitlab::Access::GUEST
+  #
+  # @param object [Project, Group] Object to be stubbed.
+  # @param access_levels [Hash<Symbol, User>, Hash<Symbol, [User]>] Map of access level to users
