Why running jasmine from cli works but through a grunt task it fails?

Question

When I run jasmine without grunt the test runs perfectly but when run with the grunt jasmine task it fails.

I think the reason for this may be because grunt is running the specs with a headless phantom js browser. While the command line jasmine just runs the tests locally.

Running from CLI: jasmine

1 spec, 0 failures

Running with Grunt-cli: grunt jasmine

Running "jasmine:test" (jasmine) task
Testing jasmine specs via PhantomJS

Gruntfile.js:

jasmine: {
          test: {
            options: {
              specs: 'spec/**/*.spec.js',
              vendor: [
                'src/js/libs/require.js',
              ]
            }
          }
        },

jasmine.json:

    "**/*.[sS]pec.js"
  ],

    "helpers/**/*.js"
