A guide for ignoring dynamic elements in Appium or WebdriverIO test scripts.
You can have elements on your screen such as dates or headlines that change dynamically. Such elements that change frequently, can pose challenges when it comes to consistent visual analysis. To avoid irrelevant differences in App Percy, you can either mock these elements to maintain consistent values or ignore these regions entirely within your App Percy test script.
To ignore specific regions within your script, App Percy offers the below options to ignore elements:
With App Percy, you can modify your script to ignore specific elements using the following options:
XPath
Accessibility ID
Pixel-based coordinates
By directly identifying the elements in your test script
The sample code for each option is shown below:
Sample code
Ignore elements using XPath
```java
import io.percy.appium.AppPercy;
import io.percy.appium.lib.IgnoreRegion;
public class Example {
private static AppPercy percy;
public static void main(String[] args) throws MalformedURLException, InterruptedException {
DesiredCapabilities caps = new DesiredCapabilities();
// Add caps here
AndroidDriver<AndroidElement> driver = new AndroidDriver<AndroidElement>(
new URL("http://hub.browserstack.com/wd/hub"), caps);
percy = new AppPercy(driver);
// Add ignore region options here
ScreenshotOptions options = new ScreenshotOptions();
List<String> ignoreRegionXpaths = new ArrayList<String>();
// add valid xpaths of element that you want to ignore in visual diff
ingoreRegionXpaths.add("some_valid_xpath");
// add those to options
options.setIgnoreRegionXpaths(ignoreRegionXpaths);
// pass options in screenshot call
percy.screenshot("Screeshot name", options);
driver.quit();
}
}
```
```csharp
