Missing coverage object- "No coverage object in the browser."

[garimamathur16]

Hi,

While working on code coverage for protractor e2e cases, using grunt-protractor-coverage, I observed this issue on test execution.

PFB the gruntfile.js

module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
// Before generating any new files, remove any previously-created files.
clean: {
tests: ['coverage', 'coverage_reports'],
},
copy: {
coverageE2E: {
files: [{
expand: true,
dot: true,
cwd: '/path/to/base/directory/',
dest: 'coverage/e2e/instrumented/app',
src: [
'WebContent/resources/css/',
'WebContent/resources/fonts/',
'WebContent/resources/html/',
'WebContent/resources/images/',
]
}]
}

    },
    instrument: {
                files: ['../WebContent/resources/js/**/*.js'],
                options: {
                    lazy: true,
                    coverageVariable: '__coverage__',
                    basePath: 'coverage/e2e/instrumented/test/'
                }
    },
    connect: {
      server: {
        options: {
          port: 3000,
          hostname: 'localhost',
        }
      },
    },
    protractor_coverage: {
        options: {
            configFile: "node_modules/protractor/example/conf.js", // Default config file 
            keepAlive: true, // If false, the grunt process stops when the test fails. 
            noColor: false, // If true, protractor will not use colors in its output. 
            //coverageDir: 'coverage/e2e/instrumented/',
            //debug: true,
            args: {
                // Arguments passed to the command 
            }
        },
        custom: {  
            options: {
                configFile: "src/conf.js", // Target-specific config file 
                 //coverageDir: 'coverage',
                 //debug: true,
                args: {
                     baseUrl: 'http://localhost:3000/',
                     // Arguments passed to the command
                    //'browser': 'firefox'
                    },

                run: {}
            }
        }
    },
    makeReport: {
      src: 'coverage/**/*.json',
      options: {
        type: 'html',
        dir: 'coverage_reports',
        print: 'detail'
      }
    }




});

//loading grunt task
grunt.loadNpmTasks('grunt-protractor-runner');
grunt.loadNpmTasks('grunt-protractor-webdriver');
grunt.loadNpmTasks('grunt-protractor-coverage');
grunt.loadNpmTasks('grunt-istanbul');
grunt.loadNpmTasks('grunt-contrib-clean');
grunt.loadNpmTasks('grunt-contrib-copy');
grunt.loadNpmTasks('grunt-contrib-connect');


//Registering task to be executed

grunt.registerTask('test', ['clean:tests','copy:coverageE2E', 'instrument' ,'connect','protractor_coverage:custom','makeReport']);

};

I suppose while providing the instrumented code to the test case at http://localhost:3000 , there appears to be some problem, as this is acting like base url, to which I have appended application relative paths when doing a browser.get('/testgui'). however, this throws the error-Angular could not be found on the page.

Is there anything I have misunderstood or missed?

Any suggestions?

i'm also getting the same error with a similar kind of Grunt file.
