Question

根据https://stackoverflow.com/a/45350941/4148175 A部分，我应该能够通过“ karma start --grep my-test-file.js”运行特定的测试文件。我试过了，但是运行了两个测试文件。

根据https://stackoverflow.com/a/29151264/4148175，我应该首先启动业力，然后运行特定的文件，但是在启动业力之后，我也触发了两个文件，当我尝试运行spesific文件时，我得到该端口未应答

据我了解，我必须设置autoWatch：true和singleRun：true，并且在我的karma.conf.js中就是这样

控制台：

Karma.conf.js

module.exports = function(config) {
  config.set({
    basePath: "",
    frameworks: ["jasmine"],
    files: [
      "node_modules/@webcomponents/webcomponentsjs/webcomponents-bundle.js",
      { pattern: "**/*.test.js", type: "module", included: true },
      { pattern: "**/*.js", type: "module", included: false }
    ],
    exclude: [],
    preprocessors: {},
    reporters: ["spec"],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ["Chrome", "Firefox"],
    singleRun: true,
    concurrency: Infinity
  });
};

总结：为了通过业力进行测试，我只是做错了什么或缺少了什么？

业力未运行特定的测试文件。而是运行所有测试文件
