Troubleshoot Test Automation Issues

​

Element not found

1. An element exists in the DOM but remains invisible.
2. Dynamic content loads after page initialization.
3. Loading indicators block element access.
4. Multiple open apps cause incorrect captured page source.

1. Add explicit wait for visibility:
   WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
   wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//button")));
   
2. Implement proper wait strategies:
   wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading")));
   
3. Use the correct syntax:
   // Correct syntax using UiSelector (recommended)
   driver.find_element('UiSelector', '{"args": {"text": "Login"}}')
   
   // Correct syntax using XPath
   //Text[@text='Login']
   
4. When dealing with multiple apps:
   • Verify current app context using driver.getContext()
   • Switch to the correct context if needed:
     driver.context("NATIVE_APP")
     // or appropriate context
     
   • Review page source before element location:
     String pageSource = driver.getPageSource();
     // Verify correct app elements are present
     
   • Close unnecessary apps or reset app state before test execution

​

Inconsistent test results

1. Element becomes invalid after page updates.
2. Dynamic IDs and attributes change between test runs.
3. Element state changes during execution.

1. Refresh elements after updates:
   element = driver.findElement(By.xpath("//button"));
   
2. Use stable attributes:
   // Stable
   "//button[contains(@class, 'login')]"
   
   // Unstable
   "//button[@id='login_123']"
   
3. Verify element state:
   wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//button")));
   

​

Performance issues

1. Complex XPath expressions.
2. Unoptimized element location strategies.
3. Repeated element lookups.

1. Use simple locators:
    // Better performance
   "//button[@text='Login']"
   
    // Slower performance
   "//*/button[contains(@text, 'Log')]/parent::*/child::button"
   
2. Cache elements:
   WebElement loginButton = driver.findElement(By.xpath("//button"));
   loginButton.click();
   

​

Framework setup

1. Incorrect Appium configuration.
2. Missing or outdated dependencies.

1. Check if your Appium configuration looks like this:
   DesiredCapabilities capabilities = new DesiredCapabilities();
   capabilities.setCapability("platformName", "Vega");
   
2. Include required dependencies and update the framework version:
   <dependency>
   <groupId>io.appium</groupId>
   <artifactId>java-client</artifactId>
   <version>latest.version</version>
   </dependency>
   

bridge = "vda"
desired_caps = {

"platformName": "Vega",

"appium:automationName": "automation-toolkit/JSON-RPC",

"browserName": "",

"kepler:device": "vda://default"

}

options = AppiumOptions()

for key, value in desired_caps.items():

options.set_capability(key, value)

appium_url = "http://127.0.0.1:4723“

driver = webdriver.Remote(appium_url, options=options)

const capabilities = {
platformName: 'Vega',
automationName: 'automation-toolkit/JSON-RPC'
// Add other capabilities as needed
};

const driver = await new webdriver.Builder()
.usingServer('http://localhost:4723/wd/hub')
.withCapabilities(capabilities)
.build();

caps = {
platformName: 'Vega',
automationName: 'automation-toolkit/JSON-RPC'

# Add other capabilities as needed
}

driver = Appium::Driver.new({
'caps' => caps,
'appium_lib' => {
server_url: 'http://localhost:4723/wd/hub‘
}
}, true)
