angularjs - Karma 覆盖率始终显示为 100%

Question

我的 karma.conf.js 文件如下所示:

// Karma configuration
// Generated on Tue Jun 11 2013 14:14:12 GMT+0100 (GMT Daylight Time)


// base path, that will be used to resolve files and exclude
basePath = '';


// list of files / patterns to load in the browser
files = [
    JASMINE,
    JASMINE_ADAPTER,
    '../Scripts/angular/angular.js',
    '../Scripts/angular/restangular/underscore-min.js',
    '../Scripts/angular/restangular/restangular-min.js',
    '../Scripts/angular/angular-*.js',
    '../Scripts/angular/angular-test/angular-*.js',
    '../Scripts/angular/angular-ui/*.js',
    '../Scripts/angular/angular-strap/*.js',
    '../Scripts/angular/angular-http-auth/*.js',
    '../uifw/scripts/ui-framework-angular.js',
    '../app/app.js',
    '../app/**/*.js',
    'unit/**/*.js'
];


// list of files to exclude
exclude = [
  '../Scripts/angular/angular-test/angular-scenario.js'
];

preprocessors = {
  '**/../app/**/*.js': 'coverage'
};



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


// test results reporter to use
// possible values: 'dots', 'progress', 'junit'
reporters = ['progress', 'coverage'];


// web server port
port = 9876;


// cli runner port
runnerPort = 9100;


// enable / disable colors in the output (reporters and logs)
colors = true;


// level of logging
// possible values: LOG_DISABLE || LOG_ERROR || LOG_WARN || LOG_INFO || LOG_DEBUG
logLevel = LOG_DEBUG;


// enable / disable watching file and executing tests whenever any file changes
autoWatch = true;


// Start these browsers, currently available:
// - Chrome
// - ChromeCanary
// - Firefox
// - Opera
// - Safari (only Mac)
// - PhantomJS
// - IE (only Windows)
browsers = ['Chrome'];


// If browser does not capture in given timeout [ms], kill it
captureTimeout = 60000;


// Continuous Integration mode
// if true, it capture browsers, run tests and exit
singleRun = false;

我的文件夹结构如下所示:

Root
 |__ App
 |__ Scripts
 |__ Tests
 |__ .... other folders

Karma.conf.js位于测试文件夹内。 Karma start karma.conf.j从 tests 内部运行文件夹。

我的测试运行并创建了一个覆盖率文件夹，但覆盖率始终显示为 100%。



我究竟做错了什么？

编辑:

事实上，这是一个简单的答案。 preprocessors = {
'**/../app/**/*.js': 'coverage'
};
不再需要以 ** 为前缀

Answer 1

使用 istanbul-instrumenter-loader 设置 webpack 让我走上了正轨。
{
test: /\.ts/,
include: helpers.root('src', 'app'),
loader: 'istanbul-instrumenter-loader',
enforce: 'post'
}
