ng test --watch = false错误代码,如果测试失败

我有问题,我认为这不正常。

当我启动命令'ng test --watch = false'时,至少有一个测试错误(期望值错误),该命令因该错误而退出

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! ulys-nav@0.0.1 test: `ng test --watch=false`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the ulys-nav@0.0.1 test script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/martels3/.npm/_logs/2019-10-21T11_20_00_883Z-debug.log

但是,当我修正测试(正确的期望)时,每一个都是正常的(没有错误)。

这是我的karma.conf.js

const puppeteer = require('puppeteer');
process.env.CHROME_BIN = puppeteer.executablePath();

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client: {
      clearContext: false, // leave Jasmine Spec Runner output visible in browser
      jasmine: {
        random: false
      }
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, '../coverage'),
      reports: ['html', 'lcovonly'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome', 'ChromeHeadless'],
    customLaunchers: {
      ChromeHeadlessCI: {
        base: 'ChromeHeadless',
        flags: ['--no-sandbox', '--disable-gpu']
      }
    },
    singleRun: false,
    captureTimeout: 210000,
    browserDisconnectTolerance: 3,
    browserDisconnectTimeout: 210000,
    browserNoActivityTimeout: 210000
  });
};

这个可怕的错误是正常现象吗? 因为当我在CI(bitRise)中启动此命令时,该命令因此退出了,我不想这样做!

答案 0 :(得分:0)

也许您仍然有问题。我认为即使不是最佳解决方案,我也为您提供解决方案。出现此类问题的原因是sourceMap属性的配置。如果您在项目中搜索关键字,则会在angular.jsontsconfig.json

中找到它

angular.json中将其设置为false,在tsconfig.json中将其设置为true。设置为true时,浏览器将断开连接,并且测试不起作用。因此解决方案是像这样配置您的命令:

ng test --source-map=false --watch=false

对我来说,这是有帮助的解决方案,因为sourceMap似乎有问题。与此GitHub问题https://github.com/karma-runner/karma/issues/3267相关,并解释了sourceMaps是什么:
