使用Selenium WebDriver with Java在组中选择单选按钮

Question

<div>
    <input type="radio" name="exampleInputRadio" id="optionRadio1" value="1">
    <input type="radio" name="exampleInputRadio" id="optionRadio2" value="2">
    <input type="radio" name="exampleInputRadio" id="optionRadio3" value="3">
    <input type="radio" name="exampleInputRadio" id="optionRadio4" value="4">
</div>

public void exampleInputRadio(WebDriver driver, int option) {
    List<WebElement> radios = driver.findElements(By.name("exampleInputRadio"));
    if (option > 0 && option <= radios.size()) {
        radios.get(option - 1).click();
    } else {
        throw new NotFoundException("option " + option + " not found");
    }
}

for (int i = 0; i < radios.size(); i++) {
    System.out.println(radios.get(i).getAttribute("id"));
}

我得到这样的输出：

optionRadio1
optionRadio2
optionRadio3
optionRadio4

这段代码在Firefox28上完全可以正常工作。我试过这样的东西：

功能：

public void exampleInputRadio(WebDriver driver, int option) {
        List<WebElement> radios = driver.findElements(By.name("exampleInputRadio"));
        if (option > 0 && option <= radios.size()) {
            radios.get(option - 1).click();
        } else {
            throw new NotFoundException("option " + option + " not found");
        }
    }

调用的函数：

TestClass tc = new TestClass();
tc.exampleInputRadio(driver, 1);
tc.exampleInputRadio(driver, 2);
tc.exampleInputRadio(driver, 3);
tc.exampleInputRadio(driver, 4);
