Karma not running a specific test file. Instead, it run all test files

Question

According to https://stackoverflow.com/a/45350941/4148175 part A I should be able to run a specific test file by "karma start --grep my-test-file.js". I tried but it run two test files I have.

According to https://stackoverflow.com/a/29151264/4148175 I should firstly start karma and then run the specific file but after I started karma I also have my two files triggered and when I try run the spesific file I get that the port isn't answering.

As far as I understood, I must setup autoWatch: true and singleRun: true and it is that way in my karma.conf.js

Console:

# karma start

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
  });
};

To summarize: what I am doing wrong or missing in order to test via karma just the tests found in a specific file?

did you try `fdescribe` or `fit` instead of `describe` and `it` blocks ? — Shashank Vivek, Jul 04 '19 at 04:06
I am currently fighting with similar symptoms. Maybe the origin is different, but for sure debugging is not easy. logLevel: config.LOG_DEBUG, gives a lot of informations. — Olivvv, Oct 16 '19 at 16:04
