Question

我可以在Protractor / Jasmine中创建一个嵌套它。

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

我正在尝试在循环中执行测试用例，并且在每次迭代中我都想运行测试，例如：

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

我想要这样做的原因是我想要初始化一个数组，然后以动态的方式循环遍历所有元素并运行一些“它”，例如：

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，我希望在初始化“it”之后执行for循环。

回答你的问题，没有你不能在其他地方嵌入它。虽然Jasmine框架不会抛出任何错误，但嵌套它中的代码并不会执行。另外，我没有看到嵌套它的任何使用，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。如果你试图在循环中运行某些东西，你可以创建另一个函数，然后在for循环中调用它，就像这样 -

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

希望这会有所帮助。有关它的更多信息，请访问此处 - Jasmine Framework - it's

如前所述 - 不，您不能将it放在另一个it块中，但是您可以将整个describe块放在另一个块中
这样做可以让您在it循环内运行for块，或，例如make it阻止条件。

你可以在下面找到一个真实的代码示例（我为了演示目的添加了for循环）

describe("E2E: Environment configuration test", function () {

    beforeAll(function () {
        logIn();
    });

    afterAll(function () {
        logOut();
    });

    describe("Members page configuration test", function() {

    for (let i=0; i<3; i++) {
        it("Members page - columns", function () {
            //code that verifies that all columns of the page are presented
        });
    }

        it( "Members page - filters", function() {            
            //code that verifies that all filters of the UI are presented as expected
        });

        it( "Members page - eligibility feature", function() {            
            //code that verifies that if the feature is set to true then additional column must be displayed
        });

    });

    describe("Providers page configuration test", function() {

    // use of conditional it blocks
    // if feature is turned on run one set it blocks
    // otherwise execute another set of it blocks
        if (envConfig.providerFeature) {

            it( "Organizations tab configuration test", function() {            
                //code that verifies that all elements of the current tab are displayed according to configurations of all features of the application 
            });

            it( "Practitioners tab configuration test", function() {});
                //code that verifies that all elements of the current tab are displayed according to configurations of all features of the application 

        } else {

            it( "Providers page - verification of the page being disabled", function() {
                //code that verifies that both tabs are not present in the UI
                console.log('Providers feature is set to FALSE for the environment by default configuration, the test case will be skipped');
            });
        }

    });

    it( "Users page configuration test", function() {
         //code that verifies that all elements of the current page are displayed according to configurations of all features of the application 
    });

    it( "Reports page configuration test", function() {

        if (!envConfig.disabledReportsFeature) {
         //code that verifies that all elements of the current page are displayed according to configurations of all features of the application 
        } else {
            console.log('Reports DISABLED_REPORTS_FEATURE is set to TRUE for the environment by default configuration, the test case will be skipped');

        }
    });
});

在这种情况下，控制台输出看起来很有条理
