appium 3-31603调试分析方法

1.Appium Log

清晰记录了所有的请求和结果

 @Test
   public void testDebug() throws InterruptedException,IOException{
        MobileElement tiaoguo = (MobileElement) driver.findElementByXPath("//*[@text='跳过']");
        FileUtils.copyFile(new File("tiaoguo.png"),tiaoguo.getScreenshotAs(OutputType.FILE));
        Thread.sleep(15000);
    }

IDE执行结果：提示方法没有实现

appium日志

通过log中可以获取更多的信息，如
在screenshot方法执行时，有URL链接，加上IP和port，访问就可以获取到更多信息。
127.0.0.1：4723/wd/hub/session/92fe82c7-02ac-4fca-a8da-eca08027f985/element/1/screenshot
可以看到/appium/node_modules/appium-base-driver/lib/basedriver/driver.js:249:13中方法未实现

2.getPageSource

界面的完整dom结构.xml文件
封装locate方法，加入异常处理，将获取的节点信息在编辑器中打开，检索控件。

    public WebElement locate(String locate){
        try {
            if (locate.matches("\/\/.*")) {
                return driver.findElementByXPath(locate);
            } else {
                return driver.findElementById(locate);
            }
        }catch (org.openqa.selenium.NoSuchElementException EX){
            System.out.println(locate);
            System.out.println(driver.getPageSource());
            return null;//没有返回值，代码会报错
        }
    }
    @Test
    public void TestDriver() throws InterruptedException{
        Thread.sleep(5000);
        //driver.findElementByXPath("//*[@text="允许"]").click();
        locate("//*[@text="允许"]").click();
        Thread.sleep(2000);
    }

因为locate中返回的null，click找不到会因找不到控件报ava.lang.NullPointerException错误

3.脚本内调试

利用xpath获取所有匹配的元素 driver.findElementByXpath("//*")

    public WebElement locate(String locate) throws InterruptedException{
        try {
            if (locate.matches("\/\/.*")) {
                return driver.findElementByXPath(locate);
            } else {
                return driver.findElementById(locate);
            }
        }catch (org.openqa.selenium.NoSuchElementException EX){
            List<AndroidElement> lists = driver.findElementsByXPath("//*");
            for(AndroidElement e:lists){
                System.out.print("tag: "+e.getTagName()+"	");
                System.out.print("text: "+e.getText()+"	");
                System.out.println("id: "+e.getAttribute("resourceId"));
                //System.out.println(e.getAttribute("contentDesc"));该属性有误，content-desc也不可用
                Thread.sleep(500);
            }
            return null;
        }
    }

FAQ

1.tagName打印null

   @Test
    public void TestDriver() throws InterruptedException{
        Thread.sleep(5000);
        List<AndroidElement> lists66 = driver.findElementsByXPath("//*");
        for(AndroidElement e66:lists66){
            System.out.print("tag: "+e66.getTagName()+"	");
            System.out.print("text: "+e66.getText()+"	");
            System.out.println("id: "+e66.getAttribute("resourceId"));
            Thread.sleep(500);
        }
        Thread.sleep(20000);
    }
