嵌套在量角器/茉莉花中 [英] Nested it in Protractor/Jasmine

问题描述

我可以在量角器/茉莉花中创建嵌套吗.

Can I create a nested it in Protractor/Jasmine.

it("outer it", function () {
    it("inner it", function () {
        expect(1).toBe(1);
    });
});

我试图在一个循环内执行它的测试用例，并且在每个迭代中我都想运行一个测试，例如:

I am trying to execute it test cases inside a loop, and in every iteration I want to run a test, for example:

it("outer it", function () {
    for(var i=0;i<10;i++){
        it("inner it", function () {
            expect(1).toBe(1);
        });
    }
});

我要这样做的原因是，我想初始化一个数组，然后以一种动态的方式循环遍历所有元素并运行多个"it"，例如:

The reason I want to do it is that I want to initialize an array and then in a dynamically way to loop trough all the element and run a number of "it", for example:

describe ("[Components]", function() {
   var grid = new Grid();

   it("Initialize the grid for the history window", function () {
       grid.init();
   });

   for(var i=0;i<grid.length;i++){
       it("test 1", function () {
           expect(1).toBe(1);
       });
   }

});

当for循环执行时，grid.length等于0，我希望for循环在初始化"it"之后执行.

The grid.length is equal to 0 when the for loop execute, I want the for loop execute after the initialize "it".

推荐答案

回答您的问题，否，您不能将它的一个嵌套在另一个内部.尽管Jasmine框架不会引发任何错误，但嵌套的 中的代码不会执行.另外，我看不到嵌套 it 的任何用途，因为它们是自行运行以完成特定测试步骤的规范或功能.它还概述了当前正在执行的功能.如果您试图在循环中运行某些内容，则可以创建另一个函数，然后在for循环中调用它，就像这样-

Answering to your question, no you cannot nest it's one inside other. Though Jasmine framework doesn't throw any error, the code inside a nested it doesn't execute. Also, I don't see any use of nesting it's as they are specs or functions that run on their own to complete a particular test step. It also gives an overview of the function that is being executed currently. If you are trying to run something in a loop, you can create another function and then call it inside the for loop, something like this -

it("outer it", function () {
    var newFunction = function(){
        expect(1).toBe(1);
    };
    for(var i=0;i<10;i++){
        newFunction();
    };
});
