AppiumDriver gives null pointer exception

Question

In my appium + testng app, what I have put is:

package com.tribehr.ios.ios_test;
import java.net.URL;
import io.appium.java_client.AppiumDriver;
import org.junit         


        

Answer 1

Surround "driver" with an if statement, to understand whether it == null.

if(driver!=null){
    System.out.println("driver does not == null");
    driver.findElement(By.xpath("YourXpath"));
} else {
    System.out.println("driver == null")
}

Here are my capabilities Working with appium 1.2*

public WebDriver appiumCapabilities() {
    File appDir = new File(System.getProperty("user.dir"), "/app/");
    File app = new File(appDir, "test.app");
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.BROWSER_NAME, "iOS");
    capabilities.setCapability(CapabilityType.PLATFORM, "Mac");
    capabilities.setCapability("platformName", "iOS");
    capabilities.setCapability("deviceName", "iPod");
    capabilities.setCapability("platformVersion", "7.1");
    capabilities.setCapability("device", "iphone");
    capabilities.setCapability("udid", "cd827d3778cfdee2fc7210f8f44184821a083c06");
    capabilities.setCapability("app", app);

    try {
        driver = new RemoteWebDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    return driver;
}
