因果报导HTML报导为空

问题描述 投票:1回答:1

我对Angular 8是不熟悉Karma的。我有很少的疑问,但没有得到正确的结果。

我的查询是:

1)我有karma conf文件,已在其中配置了代码覆盖率以在HTML coverage目录中查看,但是我没有在HTML页面中看到语句百分比等。

这是我的业力配置代码

 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
  },
  coverageIstanbulReporter: {
    dir: require('path').join(__dirname, '../coverage/my-app'),
    reports: ['html', 'lcovonly', 'text-summary'],
    fixWebpackSourcePaths: true
  },
  reporters: ['progress', 'kjhtml'],
  port: 9876,
  colors: true,
  logLevel: config.LOG_INFO,
  autoWatch: true,
  browsers: ['Chrome'],
  singleRun: false
});

2)由于我是单元测试的新手,我想了解如何为以下方法进行单元测试

navigateToStudy(row){
 this.favoriteUserId = row.id;
 this.router.navigate(['studydetails', row.id]);
}

这是我要尝试的代码。

我的规格

describe('navigatetoStudy', () => {
   it('should navigate', () =>{
    const navigate  = navigateToStudy();
    expect(navigate).toBe
   });
});

我在navigationtoStudy中出错。
