Question

我正在尝试为应用程序上的按钮点击创建循环。为此，我需要计算存在按钮的表中的行数。所以我创建了这个脚本：

require('..\\waitAbsent.js');
require("../node_modules/jasmine-expect/index.js");
var EC = protractor.ExpectedConditions;

describe('Demo_Test For count', function() {


beforeAll(function () {
    browser.driver.manage().window().maximize();
    browser.get(globalVariables.loginMain);
    globalVariables.Email_Input_box.sendKeys(globalVariables.Demo_User);
    globalVariables.Password_Input_Box.sendKeys(globalVariables.Demo_PWD);
    globalVariables.Submit_Button.click();
    browser.wait(EC.invisibilityOf(globalVariables.Submit_Button), 25000, 'submit button is not disappearing yet');
});


it('Dashboard Title Validation', function () {

    expect(globalVariables.ESY_DB_Label.isDisplayed());
    expect(globalVariables.ESY_DB_Label.getText()).toEqual('HomePage')

});

//count block


 globalVariables.tableData_Dashboard.all(by.tagName("tr")).count().then(function (Count) {

    console.log('\n the count of the rows are ' + Count + '\n');

});
//count block end


it("1+1", function () {

    let i = 1;
    let j = i + i;
    expect(j).toBe(2);

})

});

当我运行此脚本时，所有测试都将失败，即使是我刚刚添加1 + 1的第二个测试也是如此！日志如下：

  Student Enrollment Page Content Validation 1+1
  Message:
    Error: Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined.  This could be either because this is a non-angular page or because your test involves client-side
 navigation, which can interfere with Protractor's bootstrapping.  See https://github.com/angular/protractor/issues/2643 for details"

但是，如果我注释掉该块以进行计数，则测试会顺利进行。此错误的原因是什么？我该如何解决？

it块中未包含的代码将被提升到顶部并在任何it块开始之前运行，这意味着您的测试当时可能未处于预期状态。尝试再次编写代码，但要在其中包含计数块。

require('..\\waitAbsent.js');
require("../node_modules/jasmine-expect/index.js");
var EC = protractor.ExpectedConditions;

describe('Demo_Test For count', function () {  
    beforeAll(function () {
        browser.driver.manage().window().maximize();
        browser.get(globalVariables.loginMain);
        globalVariables.Email_Input_box.sendKeys(globalVariables.Demo_User);
        globalVariables.Password_Input_Box.sendKeys(globalVariables.Demo_PWD);
        globalVariables.Submit_Button.click();
        browser.wait(EC.invisibilityOf(globalVariables.Submit_Button), 25000, 'submit button is not disappearing yet');
    });


    it('Dashboard Title Validation', function () {

        expect(globalVariables.ESY_DB_Label.isDisplayed());
        expect(globalVariables.ESY_DB_Label.getText()).toEqual('HomePage')

    });

    it("1+1", function () {
       //count block
       globalVariables.tableData_Dashboard.all(by.tagName("tr")).count().then(function (Count) {
           console.log('\n the count of the rows are ' + Count + '\n');
       });
       //count block end

        let i = 1;
        let j = i + i;
        expect(j).toBe(2);

    })
});

量角器-添加计数函数将返回““ angularJS可测性和角度可测性均未定义...”错误
