从嵌套 json 向茉莉数据提供者赋值?
Assigning value to jasmine-data-provider from nested json?
我有以下 sample.json 文件。在 jasmine-data-provider 上找到的示例针对简单的 JSON 数据进行了说明。如何将以下 json 数据的值传递给数据提供者。
[
{
"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"
}]
}
]
规范文件中的用法示例如下
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,我该如何读取数据提供程序函数并为其赋值。你能给我指出正确的资源吗?
应该可以通过 jasmine-data-provider 使用标准 JSON 符号以您需要的任何方式与传递的 JSON 进行交互。或者您想在数组中的每个 JSON 块上调用它?
