如何捏-放大和缩小在Appium中的android应用中打开的图像

Question

Here's the test scenario i'm trying to automate on the app but got stuck,

• Open the app & go to photos section (Working)
• Tap on photo view it (Working)
• To confirm the photo is loaded, I want zoom in and zoom it out (Not Working)

Appium version: 1.4.16.1 API Level 19

Below is the code snippet:

@Test
 public void openph() throws InterruptedException {
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); 
        driver.findElement(By.xpath("//android.widget.ImageButton[@content-desc='Navigate up']")).click();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); 
        driver.findElement(By.xpath("//android.widget.RelativeLayout[@index='3']")).click();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); 
        driver.findElement(By.xpath("//android.widget.ImageView[@index='1']")).click();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.findElement(By.xpath("//android.widget.LinearLayout[@index='2']")).click();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.findElement(By.xpath("//android.widget.CheckedTextView[@text='Photos only']")).click();
        List<WebElement> ops = driver.findElements(By.xpath("//android.widget.ImageView"));
        ops.get(2).click();
        driver1.zoom(25, 45);
        driver1.pinch(25, 45);
        driver.manage().timeouts().implicitlyWait(120, TimeUnit.SECONDS);

 }

Can anyone please help me to get fix this.

Currently it's throwing nullpointer exception

Answer 1

Is it possibly because you have two different drivers ( driver and driver1 )? Appium is currently able to run one driver on one session at a time.

Also I don't know what you are doing with these lines: driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

You only need to start that once per driver (it also isn't very good as it will slow down your tests a lot, it would be better to use a WebDriverWait(Driver, <defined wait time>
