angular - 几次测试后出现脚本错误

Question

当我有 190 个测试时，jenkins 可以正常运行，在 191 个之后我得到以下错误:

Chrome 64.0.3282 (Linux 0.0.0) ERROR { "message": "Script error.\nat :0:0", "str": "Script error.\nat :0:0" }

谁能告诉我这是什么意思？

Karma 版本(karma --version 的输出):2.0.0

你的 karma.config.js 文件的相关部分

module.exports = function (config)
{
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular/cli'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular/cli/plugins/karma')
    ],
    client: {
      clearContext: false
    },
    files: [
      { pattern: './src/test.ts', watched: false }
    ],
    preprocessors: {
      './src/test.ts': ['@angular/cli'],
    },
    mime: {
      'text/x-typescript': ['ts', 'tsx']
    },
    coverageIstanbulReporter: {
      reports: ['html', 'lcovonly'],
      fixWebpackSourcePaths: true
    },

    angularCli: {
      environment: 'dev'
    },
```
    reporters: config.angularCli && config.angularCli.codeCoverage
      ? ['progress', 'coverage-istanbul']
      : ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,

    browsers: ['Chrome_no_sandbox', 'Chrome'], customLaunchers: {
      Chrome_no_sandbox: {
        base: 'Chrome',
        flags: ['--no-sandbox'] // for running within Docker
      }
    },
    singleRun: false,
    colors: true
  });
};`

使用 --single-run=false 选项运行 Karma，这是默认选项，例如

karma 开始 --single-run=false --config=test/unit/karma.conf.js

然后，打开 http://localhost:9876/debug.html 并打开控制台。您会在那里看到实际问题。
