如何在Selenium测试中注入JS函数? [英] How do I inject a JS function in my Selenium tests?

问题描述

我正在将Selenium客户端驱动程序2.5.0与WebBackedSeleniumDriver一起使用.我想注入一个Javascript函数供我的测试使用，但是遇到了一些麻烦.这是我初始化驱动程序的方式……

I'm using Selenium client driver 2.5.0 with the WebBackedSeleniumDriver. I want to inject a Javascript function for use across my tests, but am having some trouble. Here's how I initialize my driver …

    final FirefoxDriver driver = new FirefoxDriver();
    selenium = new WebDriverBackedSelenium(driver, baseUrl); 

但是下面的第二行会抛出'inc'未定义错误".

but the second line below throw an "'inc' undefined error."

    selenium.getEval("function inc(x) { return x + 1; }); ");
    String incResult = selenium.getEval("inc(5);");

有什么想法可以成功注入Javascript函数以用于其他测试吗?

Any ideas how I can successfully inject a Javascript function for use in other tests?

谢谢-戴夫
