I am currently using Karma as my test runner with Webpack. I've noticed that simple test files which contain no tests give me 92.86% statement coverage, 50% branch coverage, 100% function coverage, and 92.86% line coverage.
describe('tests.js', function () {
});
When I check where I'm missing coverage I'm seeing this code (line 10), which is injected into my module by Webpack, as not being covered by tests:
if(installedModules[moduleId])
return installedModules[moduleId].exports;
I can't test for this because Webpack is injecting this code into the module. So how do I stop this type of information from being included in the coverage report?
The entire rendered file that the coverage report is giving me is the following:
/******/ (function(modules) { // webpackBootstrap
/******/ // The module cache
/******/ var installedModules = {};
/******/ // The require function
/******/ function __webpack_require__(moduleId) {
/******/ // Check if module is in cache
/******/ Iif(installedModules[moduleId])
/******/ return installedModules[moduleId].exports;
/******/ // Create a new module (and put it into the cache)
/******/ var module = installedModules[moduleId] = {
/******/ exports: {},
/******/ id: moduleId,
/******/ loaded: false
/******/ };
/******/ // Execute the module function
/******/ modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);
/******/ // Flag the module as loaded
/******/ module.loaded = true;
/******/ // Return the exports of the module
/******/ return module.exports;
/******/ }
/******/ // expose the modules object (__webpack_modules__)
/******/ __webpack_require__.m = modules;
/******/ // expose the module cache
/******/ __webpack_require__.c = installedModules;
/******/ // __webpack_public_path__
/******/ __webpack_require__.p = "/_karma_webpack_//";
/******/ // Load entry module and return exports
/******/ return __webpack_require__(0);
/******/ })
/************************************************************************/
/******/ ([
/* 0 */
/***/ function(module, exports) {
'use strict';
describe('tests.js', function () {});
/***/ }
/******/ ]);
I don't want things like jQuery and Webpack items included as part of the code coverage report. How can I exclude things like the above code as being excluded from my tests? Because a test file with no tests and no imports/requires should be 100% coverage.
