skonfiguruj pokrowiec na karmę Web Pack z kanciastą 2

Question

Jak ustawić karmę-pokrycie przy użyciu pakietu webowego kątowego2 +?

Śledziłem przewodnik po pakiecie dla początkujących z kanciastą. Ale narzędzie do pokrycia jest puste i nie wyświetla moich testów. Dzięki!

moja struktura folderów jest

project 
|--src (project files) 
|--tests (all my testfiles) 

moi webpack.test.js wygląda to

var helpers = require('./helpers'); 

module.exports = { 
    devtool: 'inline-source-map', 

    resolve: { 
     extensions: ['', '.ts', '.js'] 
    }, 

    module: { 
     loaders: [ 
      { 
       test: /\.ts$/, 
       loaders: ['ts'] 
      }, 
      { 
       test: /\.html$/, 
       loader: 'null' 

      }, 
      { 
       test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/, 
       loader: 'null' 
      }, 
      { 
       test: /\.css$/, 
       exclude: helpers.root('src', 'app'), 
       loader: 'null' 
      }, 
      { 
       test: /\.css$/, 
       include: helpers.root('src', 'app'), 
       loader: 'null' 
      } 
     ] 
    } 
} 

mój Karma.conf.js

var webpackConfig = require('./webpack.test'); 

module.exports = function (config) { 
    var _config = { 
     basePath: '', 

     frameworks: ['jasmine', 'sinon'], 

     files: [ 
      {pattern: './config/karma-test-shim.js', watched: false} 
     ], 
     preprocessors: { 
      './config/karma-test-shim.js': ['webpack', 'sourcemap'] 
     }, 
     plugins:[ 
      require('karma-jasmine'), 
      require('karma-coverage'), 
      require('karma-webpack'), 
      require('karma-phantomjs-launcher'), 
      require('karma-sourcemap-loader'), 
      require('karma-mocha-reporter'), 
      require('karma-sinon') 
     ], 

     coverageReporter: { 
      type : 'html', 
      dir : 'coverage/' 
     }, 

     webpack: webpackConfig, 

     webpackMiddleware: { 
      stats: 'errors-only' 
     }, 

     webpackServer: { 
      noInfo: true 
     }, 

     reporters: ['mocha','coverage'], 
     port: 9876, 
     colors: true, 
     logLevel: config.LOG_INFO, 
     autoWatch: true, 
     browsers: ['PhantomJS'], 
     singleRun: false 
    }; 

    config.set(_config); 
}; 

i karma-test- shim.js

Error.stackTraceLimit = Infinity; 

require('core-js/es6'); 
require('reflect-metadata'); 

require('zone.js/dist/zone'); 
require('zone.js/dist/long-stack-trace-zone'); 
require('zone.js/dist/proxy'); 
require('zone.js/dist/sync-test'); 
require('zone.js/dist/jasmine-patch'); 
require('zone.js/dist/async-test'); 
require('zone.js/dist/fake-async-test'); 

var testContext = require.context('../tests', true, /\.spec\.ts/); 

testContext.keys().forEach(testContext); 

var testing = require('@angular/core/testing'); 
var browser = require('@angular/platform-browser-dynamic/testing'); 

testing.TestBed.initTestEnvironment(browser.BrowserDynamicTestingModule, browser.platformBrowserDynamicTesting());

Yuu trzeba importować poniżej wtyczki pokrycie kodu do wtyczek

require('karma-coverage-istanbul-reporter'), 

również skorzystać z poniższego kodu, aby dodać istanbul własność reportera jak poniżej

coverageIstanbulReporter: { 
     reports: ['html', 'lcovonly'], 
     fixWebpackSourcePaths: true, 
     // enforce percentage thresholds 
     // anything under these percentages will cause karma to fail with an exit code of 1 if not running in watch mode 
     thresholds: { 
      emitWarning: false, // set to `true` to not fail the test command when thresholds are not met 
      global: { // thresholds for all files 
       statements: 80, 
       lines: 80, 
       branches: 80, 
       functions: 80 
      }, 
      each: { // thresholds per file 
       statements: 80, 
       lines: 80, 
       branches: 80, 
       functions: 80, 
       overrides: {} 
      } 
     } 
    }, 

Kompletny config dla karma.config.js powinny być poniżej:

// Karma configuration file, see link for more information 
// https://karma-runner.github.io/0.13/config/configuration-file.html 

module.exports = function(config) { 
    config.set({ 
     basePath: '', 
     frameworks: ['jasmine', '@angular/cli'], 
     plugins: [ 
      require('karma-jasmine'), 
      require('karma-chrome-launcher'), 
      require('karma-jasmine-html-reporter'), 
      require('karma-coverage-istanbul-reporter'), 
      require('@angular/cli/plugins/karma'), 
      require('karma-htmlfile-reporter'), 
     ], 
     client: { 
      clearContext: false // leave Jasmine Spec Runner output visible in browser 
     }, 
     coverageIstanbulReporter: { 
      reports: ['html', 'lcovonly'], 
      fixWebpackSourcePaths: true, 
      // enforce percentage thresholds 
      // anything under these percentages will cause karma to fail with an exit code of 1 if not running in watch mode 
      thresholds: { 
       emitWarning: false, // set to `true` to not fail the test command when thresholds are not met 
       global: { // thresholds for all files 
        statements: 80, 
        lines: 80, 
        branches: 80, 
        functions: 80 
       }, 
       each: { // thresholds per file 
        statements: 80, 
        lines: 80, 
        branches: 80, 
        functions: 80, 
        overrides: {} 
       } 
      } 
     }, 
     angularCli: { 
      environment: 'dev' 
     }, 
     // reporters: config.angularCli && config.angularCli.codeCoverage ? ['spec', 'karma-remap-istanbul'] : ['spec'], 
     // reporters: ['mocha'], 
     reporters: ['progress', 'html', 'kjhtml'], 
     htmlReporter: { 
      outputFile: 'testreports/report.html', 
      // Optional 
      pageTitle: 'Rest Reports', 
      subPageTitle: 'Suite-wise report ', 
      groupSuites: true, 
      useCompactStyle: true, 
      useLegacyStyle: false 
     }, 
     port: 9876, 
     colors: true, 
     logLevel: config.LOG_INFO, 
     autoWatch: true, 
     browsers: ['Chrome'], 
     singleRun: false 
    }); 
};
