Question

我正在开发一个项目，我必须使用Jasmine测试我的js代码。我写了这样的测试。

describe("Function: foo() --- File: foo.js", function() {
    it("if input is integer", function () {
        var result = foo(123);
        expect(result).toBe(123);
    });

    it("If input is string", function () {
        var result = foo('String');
        expect(result).toBe('String');
    });

    it("If input is empty string", function () {
        var result = foo('');
        expect(result).toBe('');
    });

});

正如代码所示，我正在重复同样的事情＆＃39;它＆＃39;一次又一次阻止。只有正在改变的是描述，输入功能和输出＆＃34; toBe＆＃34;。我想询问是否有一种方法可以在list / dictionary中添加我的方案，并在我的测试中使用它们而不使用任何for循环

describe("Function: foo() --- File: foo.js", function() {
    scenarios = [
        {description: "if input is integer", input: 123, output: 123},
        {description: "if input is String", input: "String", output: "String"},
        {description: "if input is empty string", input: '', output: ''},
    ]; 

    //This will run for each scenario in above list
    it(this.description, function () {
        var result = foo(this.input);
        expect(result).toBe(this.output);
    });

});

在这种情况下，任何人都可以帮助我吗？

您可以使用using：

实现您想要的效果

describe("Function: foo() --- File: foo.js", function() {
var scenarios = [
        {description: "if input is integer", input: 123, output: 123},
        {description: "if input is String", input: "String", output: "String"},
        {description: "if input is empty string", input: '', output: ''},
    ];

scenarios.map(function(value) {
    it(value.description, function() {
        var result = foo(value.input);
        expect(result).toBe(value.output);
    });
});
}
