Javascript 如何在Jasmine JS的selenium webdriver中存储一个随机值并通过单击函数调用它？

我想保存一个介于1到31之间的随机数，并通过“单击”功能使用它，以便通过“链接文本”定位器单击保存的随机数

可能吗

我需要像这样的东西：

 var randomDay = Math.floor(31*Math.random() + 1);
 element(by.linkText(randomDay)).click();

完整测试如下：

describe('Selenium Test Case', function() {

beforeEach(function(){
    browser.ignoreSynchronization = true;
});

afterEach(function(){
    browser.ignoreSynchronization = false;
});

  it('should execute test case without errors', function() {
    var text, value, bool, source, url, title;
    var TestVars = {};
    var randomDay = Math.floor(31*Math.random() + 1);

browser.get("https://www.mywebsite.com/");
    captureScreen();
browser.driver.sleep(3000);
element(by.xpath("//div[@class='actions-row']//a[.='Schedule Now']")).click();
    captureScreen();
browser.driver.sleep(3000);
element(by.css("div.service-info")).click();
    captureScreen();
browser.driver.sleep(3000);
element(by.css("span.gray-button-style")).click();
browser.driver.sleep(3000);
element(by.linkText("Next")).click();
browser.driver.sleep(3000);
    element(by.linkText(randomDay)).click();
browser.driver.sleep(3000);
element(by.id("class=icon")).click();
browser.driver.sleep(3000);
element(by.linkText("Continue")).click();
element(by.name("email")).sendKeys("idanvcita@gmail.com");
element(by.xpath("(//textarea[@id='agenda'])[2]")).sendKeys("hello again");
element(by.linkText("Submit")).click();
element(by.linkText("Done")).click();
    captureScreen();
browser.driver.sleep(3000);
  });
});

错误如下：

describe('Selenium Test Case', function() {

beforeEach(function(){
    browser.ignoreSynchronization = true;
});

afterEach(function(){
    browser.ignoreSynchronization = false;
});

  it('should execute test case without errors', function() {
    var text, value, bool, source, url, title;
    var TestVars = {};
    var randomDay = Math.floor(31*Math.random() + 1);

browser.get("https://www.mywebsite.com/");
    captureScreen();
browser.driver.sleep(3000);
element(by.xpath("//div[@class='actions-row']//a[.='Schedule Now']")).click();
    captureScreen();
browser.driver.sleep(3000);
element(by.css("div.service-info")).click();
    captureScreen();
browser.driver.sleep(3000);
element(by.css("span.gray-button-style")).click();
browser.driver.sleep(3000);
element(by.linkText("Next")).click();
browser.driver.sleep(3000);
    element(by.linkText(randomDay)).click();
browser.driver.sleep(3000);
element(by.id("class=icon")).click();
browser.driver.sleep(3000);
element(by.linkText("Continue")).click();
element(by.name("email")).sendKeys("idanvcita@gmail.com");
element(by.xpath("(//textarea[@id='agenda'])[2]")).sendKeys("hello again");
element(by.linkText("Submit")).click();
element(by.linkText("Done")).click();
    captureScreen();
browser.driver.sleep(3000);
  });
});

失败：

您似乎有铸造错误。尝试将数字作为字符串传递。

应该是这样的：

var randomDay = Math.floor(31*Math.random() + 1);
var randomDayLink = randomDay.toString(); 
element(by.linkText(randomDayLink)).click();

你贴的例子有什么问题？看起来您首先使用所需的随机数初始化变量，然后单击带有链接文本（如随机数）的元素。正是你所期望的。我知道，但它不起作用：/你得到了什么错误或异常？我已经在文章底部添加了错误，谢谢！Outlook -考虑停止使用浏览器。驱动程序。睡眠（3000），尝试更聪明的等待。示例如下：
