How to clear karma warn web-server 404 error for Service method call?

Question

I am new to TDD. I have configured the karma and gulp for my sources to generate the code coverage. My karma configuration file is given below:

    browsers: ['Chrome', 'IE', 'Firefox', 'MyHeadlessChrome'],
        frameworks: ['jquery-1.10.2', 'jasmine-jquery', 'jasmine'],
        files: [
        '**/**/**/**/**.*',
        
        {
            pattern: 'js/**/**/**.html',
            watched: true,
            served: true,
            included: false
        }
        ],
        port:9878,
        concurrency: Infinity,
        browserDisconnectTolerance: 3,
        browserNoActivityTimeout: 1000000,
        browserDisconnectTimeout: 1000000,
        captureTimeout: 1000000,
        retryLimit: 5,

While execution test cases, I am getting below error, a method was in service. It shows that, method was not found.

My package.json configuration is given below:

    "devDependencies": {
    "eslint-html-reporter": "^0.5.2",
    "ghooks": "^1.2.4",
    "gulp": "^3.9.0",

    "karma-jasmine-jquery-2": "^0.1.1",
    "karma-jquery": "^0.1.0",
    "karma-safari-launcher": "^1.0.0"
     },

The karma-warning is given below:
