Javascript 从嵌套json向jasmine数据提供程序赋值？

我有以下sample.json文件。上的示例演示了简单JSON数据。如何将以下json数据的值传递给数据提供程序

     [
  {
        "company_name": "Google",
        "Headquartered_at": "Mountain view",
        "Department": [
          {
            "name": "Engineering",
            "number_of_subDepartment": "3",
            "subDepartments": [
              {
                    "subDepartment_name": "Developers",
                    "no_of_employees": "10"
                },
                {
                    "subDepartment_name": "SRE",
                    "no_of_employees": "10"
                },
                {
                    "subDepartment_name": "QA",
                    "no_of_employees": "10"
                }
            ]
        }, {
            "name": "Human resources",
            "number_of_subDepartment": "0"
        }]
    },
  {
        "company_name": "Microsoft",
        "Headquartered_at": "Redmond",
        "Department": [
          {
            "name": "Engineering",
            "number_of_subDepartment": "2",
            "subDepartments": [
              {
                    "subDepartment_name": "Developers",
                    "no_of_employees": "10"
                },
                {
                    "subDepartment_name": "QA",
                    "no_of_employees": "10"
                }
            ]
        }, 
          {
            "name": "Human resources",
            "number_of_subDepartment": "0"
        }]

    },
  {
        "company_name": "Facebook",
        "Headquartered_at": "Menlo park",
        "Department": [
          {
            "name": "Engineering",
            "number_of_subDepartment": "2",
            "subDepartments": [
              {
                    "subDepartment_name": "Developers",
                    "no_of_employees": "10"
                },
                {
                    "subDepartment_name": "QA",
                    "no_of_employees": "10"
                }
            ]
        }, 
          {
            "name": "Human resources",
            "number_of_subDepartment": "0"
        }]
    }


]

spec文件中的用法示例如下所示

describe('test addition with data provider - provider function', function () {
    function plusProvider() {
        return [
            {a: 2, b: 3, expected: 5},
            {a: '14', b: 15, expected: 29},
            {a: 12, b: '13', expected: 25},
            {a: '22', b: '13', expected: 35},
        ];
    }

    using(plusProvider, function (data) {
        it('should calc with operator +', function () {
            var result = calculator.calc(data.a, data.b, '+');

            expect(result).toEqual(data.expected);
        });
    });
});

由于sample.json文件更复杂，如何读取数据提供程序函数并为其赋值。您能给我指出正确的参考资料吗。

应该可以使用jasmine数据提供程序的标准JSON符号，以您需要的任何方式与传递的JSON进行交互。还是要在数组中的每个JSON块上调用它

datafile.json
