Question

我将karma与karma-typescript一起使用（但这不是Angular项目，因此我没有使用angular-cli）。

大约一半的测试运行在所有测试通过后都会产生错误，我对如何进行感到困惑。这是输出。

$ karma start karma.conf.js --single-run --jenkins

（在我的--jenkins中使用karma.conf.js标志主要是确定是否使用ChromeHeadless而不是Chrome –见下文）。

我相当确定此错误不是由我的代码引起的。

相关软件包：

    "@types/jasmine": "^3.3.8",
    "@types/jasminewd2": "^2.0.6",
    "awesome-typescript-loader": "^5.2.1",
    "jasmine": "^3.3.1",
    "jasmine-core": "^3.3.0",
    "karma": "^4.0.0",
    "karma-chrome-launcher": "^2.2.0",
    "karma-cli": "^2.0.0",
    "karma-jasmine": "^2.0.1",
    "karma-jasmine-html-reporter": "^1.4.0",
    "karma-junit-reporter": "^1.2.0",
    "karma-typescript": "^4.0.0",
    "ts-loader": "^5.3.3",
    "typescript": "^3.2.4"

最后，这是我的karma.conf.js：

module.exports = function(config) {
  const jenkins = config.jenkins;
  config.set({
    basePath: '',
    frameworks: ["jasmine", "karma-typescript"],
    plugins: [
      require('karma-jasmine'),
      require("karma-chrome-launcher"),
      require("karma-typescript"),
      jenkins ? require('karma-junit-reporter') : require('karma-jasmine-html-reporter')
    ],
    client:{
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    files: [
      "src/**/*.ts"
    ],
    preprocessors: {
      "src/**/*.ts": "karma-typescript"
    },
    reporters: [
      'progress', (jenkins ? 'junit' : 'kjhtml'), 'karma-typescript'
    ],
    browsers: [jenkins ? 'ChromeHeadless' : 'Chrome'],
    karmaTypescriptConfig: {
      tsconfig: "./tsconfig.json",
      coverageOptions: {
        exclude: [/mock/, /\.spec\.ts$/, /testing-utils/]
      }
    },
    colors: !jenkins,
    logLevel: config.LOG_INFO,
    autoWatch: !jenkins,
    singleRun: jenkins,
    junitReporter: {
      outputDir: 'karma-results',
      outputFile: 'karma-results.xml'
    }
  });
};

如何调试因果服务器中的错误？
