how to test when we have more than one spec.js file

[sirishasriramineni207]

Expected behaviour

I am new to require.js with karma.
my tree s like below

it should pass all the tests.

Actual behaviour

when there is one spec.js for example aSpec.js it is running fine.
when adding an other spec.js, karma is not running properly and giving errors in aSpec.js. This is weird.

Environment Details

frameworks: ['jasmine', 'requirejs'],

• Karma version (output of karma --version):
  

• Relevant part of your karma.config.js file
  module.exports = function (config) {
  config.set({

  // base path, that will be used to resolve files and exclude
  basePath: '',

  // frameworks to use
  frameworks: ['jasmine', 'requirejs'],

  // list of files / patterns to load in the browser
  files: [
  {pattern: 'test//*Spec.js', included: false},
  {pattern: 'src//*.js', included: false},
  'submit_po3_validations.js',
  'ups_lib.js',
  'submit_po3.js',
  'so_entry_checks_client.js',
  'so_entry_checks_ue.js',
  './test/test_so_ue.js',
  'submit_lib.js',
  'library.js',
  'set_dc_on_so_ue.js',
  'set_cust_info_ue.js',
  'send_email_to_customer.js',
  'create_marketplace_cust_dep_ue.js',
  './test/test_library.js',
  './test/test_set_cust_info_ue.js',
  './test/test_send_email_to_customer.js',
  './test/submit_po_tests.js',
  './test/submit_po_validations_tests.js',
  './test/test_so_entry_checks_client.js',
  './test/submit_lib_tests.js',
  './test/TestSetDCSalesOrder.js',
  './test/ups_lib_tests.js',
  './test/test_create_marketplace_cust_dep_ue.js',
  'test/test-main.js',
  ],

  exclude: [
  ],

  reporters: ['dots', 'junit'],

  // web server port
  port: 9876,

  // enable / disable colors in the output (reporters and logs)
  colors: true,

  // level of logging
  // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
  logLevel: config.LOG_INFO,

  // enable / disable watching file and executing tests whenever any file changes
  autoWatch: true,
  browsers: [//'PhantomJS',
  'Chrome'],

  captureTimeout: 60000,

  // Continuous Integration mode
  // if true, it capture browsers, run tests and exit
  singleRun: true
  });
  };

Any ideas what is going on here.
Thanks
