// NOTE: Due to the use of dynamic imports this is not included in Special:JavaScript build
// This tests the importable nature of the MobileFrontend code library.
// It also ensures we add test coverage for files without any
// (loosely inspired by https://github.com/istanbuljs/nyc/issues/594)
// If a module cannot be tested with Node.js it needs to be added to .nyrc.json
