Question

我为使用karma＆amp; amp;设置的应用设置进行单元测试摩卡＆amp;通过伊斯坦布尔报道。

npm脚本：

"test": "cross-env BABEL_ENV=test karma start tests/karma.conf.js --single-run",

我想要做的是在开发过程中运行一个脚本来观察测试＆amp;应用程序文件进行更改并根据需要重新运行测试。

我尝试将--single-run替换为--auto-watch：

"test:watch": "cross-env BABEL_ENV=test karma start tests/karma.conf.js --auto-watch",

但这会不断重复 - 一旦完成一轮测试，它就会重新开始。

karma.conf.js：

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

module.exports = function (config) {
  config.set({
    browsers: ['PhantomJS'],
    frameworks: ['mocha', 'sinon-chai', 'phantomjs-shim'],
    reporters: ['spec', 'coverage'],
    files: ['./index.js'],
    preprocessors: {
      './index.js': ['webpack', 'sourcemap'],
    },
    webpack: webpackConfig,
    webpackMiddleware: {
      noInfo: true
    },
    coverageReporter: {
      dir: './coverage',
      reporters: [
        { type: 'lcov', subdir: '.' },
        { type: 'text' }
      ]
    }
  });
};

webpack.conf.test.js

var path = require('path');
var webpack = require('webpack');
var vueLoaderConfig = require('./vue-loader.conf.js');
var eslintFormatter = require('eslint-friendly-formatter');
var HtmlWebpackPlugin = require('html-webpack-plugin');

function resolve(dir) {
  return path.join(__dirname, '..', dir);
}

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

    path: path.resolve(__dirname, '../dist/js'),
    filename: 'build.js',
    publicPath: '/ntx/js/'

        include: [resolve('src'), resolve('test')]

          limit: 10000,
          name: path.posix.join('./dist/img', 'img/[name].[hash:7].[ext]')
        }
      }
    ]
  }
};

有没有办法做我正在寻找的事情？

结帐Karma configuration options。

您可以使用--no-single-run代替--single-run在观看模式中运行测试。您也应该可以使用--auto-watch运行此功能。

从命令行/ npm脚本运行文件更改时的karma
