waitForAngular 和 "then" 都没有按预期工作

Question

我尝试了 this Q&A 中提到的所有变体：

第一个

 element(by.css('[ng-click="vm.openNewPage()"]')).click().then(function () {
        expect(element(by.css('[ng-click="vm.submitButtonOfThatPage()"]')).isPresent()).toBe(true);
    });

第二个

element(by.css('[ng-click="vm.openNewPage()"]'));
browser.waitForAngular();        
expect(element(by.css('[ng-click="vm.submitButtonOfThatPage()"]')).isPresent()).toBe(true);

第三个：

element(by.css('[ng-click="vm.openNewPage()"]'));
browser.sleep(1)
browser.waitForAngular();        
expect(element(by.css('[ng-click="vm.submitButtonOfThatPage()"]')).isPresent()).toBe(true);

none 个通过测试：预期假为真。除了这个 browser.sleep(1000)

element(by.css('[ng-click="vm.openNewPage()"]'));
browser.sleep(1000)
expect(element(by.css('[ng-click="vm.submitButtonOfThatPage()"]')).isPresent()).toBe(true);

为睡眠时间设置几秒钟显然不是解决方案。

我错过了什么或者我应该怎么做才能成功评估测试

Protractor 版本为：Jasmine2 框架版本 2.1.0

这是我开始测试的命令：

C:\projects\eucngts\e2e\app>protractor conf.js --baseUrl=http://localhost:56225/euc/

这些是我的相关代码：

// conf.js
exports.config = {
    directConnect: true,
    seleniumAddress: 'http://localhost:4444/wd/hub',
    framework: 'jasmine2',
    specs: [
        './views/account/loginSpec.js'
        ,'./views/inStudents/inStudentsSpec.js'
    ]
}

//Spec File
describe('Testing Students Page', function () {

    var inStudents: InStudents = require('./inStudents.js');
    var defs: Defs = require('../defs.js');
    it('should check cell 2 2 ', function () {
        inStudents.createNewInStudent()
    });
});

//Testing file

class InStudents {

        createNewInStudent() {
            element(by.css('[ng-click="vm.openNewPage()"]'));
            browser.sleep(1000)
            expect(element(by.css('[ng-click="vm.submitButtonOfThatPage()"]')).isPresent()).toBe(true);
        }
    }
module.exports = new InStudents();

Answer 1

而不是 browser.sleep() 延迟，用 browser.wait() and wait for the element to become present 明确表示：

var submitButton = element(by.css('[ng-click="vm.submitButtonOfThatPage()"]'));
var EC = protractor.ExpectedConditions;
browser.wait(EC.presenceOf(submitButton), 5000);

waitForAngular 和 "then" 都没有按预期工作

Neither waitForAngular nor "then" work as expected
