相关疑难解决方法(0)

我正在使用Selenium WebDriver(Java)和TestNG在我创建的网站上进行一些测试.在这个网站上,我也有JavaScript,在一些函数中,它返回值并通过输出值输出到浏览器控制台console.log().

我想知道Selenium WebDriver是否有一种简单的方法可以访问这些JavaScript信息,因此我可以使用TestNG执行断言.

我对Selenium很新,但我知道你可以这样做:

WebDriver driver = new ChromeDriver();
driver.findElement(By.id("btn")).click();

那么我可以用什么类似的东西WebDriver来阅读网站上的JavaScript？

澄清

看起来人们假设我正试图通过Selenium"执行"JavaScript代码.

不是这样的.相反,我正在尝试使用Selenium存储已定义的JavaScript变量.

基本上,我希望Selenium能够获取JavaScript变量的值,将其存储在本地,然后对其进行断言测试.

尝试1

说我的网站有以下JS代码:

$(document).ready(function() {
    var foo = $(#"input-field-val").val();

    function returnFoo() {
        return foo;
    }
});

根据我的阅读和理解,在我单独的Selenium测试文件(Selenium.java)中,我应该可以做这样的事情吗？:

public class Selenium {
    WebDriver driver = new FirefoxDriver();
    JavascriptExecutor js = (JavascriptExecutor) driver;

    @Test
    public void testSample() {
        driver.get("www.mywebsite.com");
        js.executeScript("alert(returnFoo());");
    }
}

我做了类似于上面的事情,但没有弹出警报框.相反,我收到一条错误消息:

Exception in thread "main" org.openqa.selenium.WebDriverException: ReferenceError: returnFoo is not defined

当我说JS变量时,我很确定我不明白它意味着什么

不应该是闭包或局部变量的一部分

我也尝试在上面定义一个全局变量,$(document).ready(function()...并且设置在function returnFoo()但仍然不起作用.
