Question

使用android驱动程序未初始化Object映射。每当尝试使用任何sendkeys或点击时，该对象都会抛出null pointer exception。

请在下面找到代码段： -

OR中使用的代码：

@FindAll({ @FindBy(xpath = "//*[@id='tsbb']") })
    public WebElement Google_homepage__ssearchBTN;

WebDriver driver;
public tesitng_android_om(WebDriver driver){
    this.driver=driver;
}

内部测试用例：

        Android driver = new AndroidDriver(sURL, oCap); 

        tesitng_android_om tesitng_android_om = new tesitng_android_om((WebDriver)driver);

        PageFactory.initElements((WebDriver)driver,tesitng_android_om);

        tesitng_android_om.Google_homepage__ssearchBTN.click();

相同的代码适用于 Selenium 3.4.0 ，但无法在 3.8.1中运行

Answer 1

而不是以下代码块：

tesitng_android_om tesitng_android_om = new tesitng_android_om((WebDriver)driver);
PageFactory.initElements((WebDriver)driver,tesitng_android_om);

替换为：

tesitng_android_om tesitng_android_om_page = PageFactory.initElements(driver, tesitng_android_om.class);

使用Selenium 3.8.1运行android驱动程序时抛出空指针异常的对象
