我们试图让建筑管道对角度进行单元测试，这在第一次尝试中效果很好。第二次尝试失败，并显示以下错误：
✓ should create

}
每次测试均成功，但此后均发生此错误。我想知道为什么，所以我又重新运行了。成功。但是之后的构建又因相同的问题而失败。从那以后，第二个构建都失败了。
在通过Google的途中，我发现了一些似乎很相似的问题。一个人说可能会出现问题，因为测试将以随机顺序进行。因此，我禁用了您可以在下面的karma.conf.js中看到的随机顺序。
另一个人说他能够使用'karma-spec-reporter'查找错误，所以我也将它添加到了conf中。
我的conf现在看起来像这样：
// Karma configuration file, see link for more information
// https://karma-runner.github.io/1.0/config/configuration-file.html
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('karma-spec-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/hts'),
reports: ['html', 'lcovonly', 'text-summary'],
fixWebpackSourcePaths: true
},

port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false,

});
};
以下是测试失败的日志：
