Appium with C#

In this documentation, you will learn how to trigger a automation script of CSharp for application testing with Appium on LambdaTest, set the desired capabilities for appium testing, and other advanced features of LambdaTest.


  • Your LambdaTest Username and Access key.
  • Install the MS Visual Studio 2013 or later version for C#. We recommend using the latest version.

Try our Sample Repository

Step 1: Get a Sample Project

You can use your own project to configure and test it. For demo purposes, we are using the sample repository.

Sample repo

All the code samples in this documentation can be found on LambdaTest's Github Repository. You can either download or clone the repository to quickly run your tests. Image View on GitHub

Open the Android/iOS project using the file with a .sln extension.

Step 2: Setup the Environment Variables

You need to export your environment variables LT_USERNAME and LT_ACCESS_KEY that are available in your LambdaTest Profile page. Run the below mentioned commands in your terminal to setup the environment variables.

export LT_USERNAME="undefined"
export LT_ACCESS_KEY="undefined"

Step 3: Upload your Application

Upload your iOS application (.ipa file) or android application (.apk or .aab file) to the LambdaTest servers using our REST API. You need to provide your Username and AccessKey in the format Username:AccessKey in the cURL command for authentication.

Make sure to add the path of the appFile in the cURL request. Below is an example cURL request to upload your app using our REST API:

curl -u "undefined:undefined" -X POST "" -F "appFile=@"/Users/macuser/Downloads/proverbial_android.apk"" -F "name="proverbial_app""
  • If you do not have any .apk or .ipa file, you can run your sample tests on LambdaTest by using our sample apps, 🔗 Android app or 🔗 iOS app.

  • Response of above cURL will be a JSON object containing the APP_URL of the format - lt://APP123456789123456789 and will be used in the next step

Step 4: Update your Automation Script

An automation script for the sample application given above has been provided here. Ensure to update the APP_URL, username and accessKey in the code scripts before running the tests.

using System;
using OpenQA.Selenium.Appium;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Appium.iOS;
using System.Threading;

namespace csharp_appium_first

class Program
static void Main(string[] args)
AppiumOptions caps = new AppiumOptions();

// Set your LambdaTest access credentials
caps.AddAdditionalCapability("LT_USERNAME", "username"); //Enter the Username here
caps.AddAdditionalCapability("LT_ACCESSKEY", "accessKey"); //Enter the Access key here

// Set URL of the application under test
caps.AddAdditionalCapability("app", "APP_URL"); //Enter the App URL here.

// Specify device and os_version
caps.AddAdditionalCapability("deviceName", "iPhone 12"); //Change the device name here
caps.AddAdditionalCapability("platformVersion", "15");
caps.AddAdditionalCapability("platformName", "iOS");
caps.AddAdditionalCapability("isRealMobile", true);
caps.AddAdditionalCapability("network", false);

// Specify the platformName
//caps.PlatformName = "iOS";

// Set other LambdaTest capabilities
caps.AddAdditionalCapability("project", "First CSharp project");
caps.AddAdditionalCapability("build", "CSharp iOS");
caps.AddAdditionalCapability("name", "first_test");

// Initialize the remote Webdriver using LambdaTest remote URL
// and desired capabilities defined above
IOSDriver<IOSElement> driver = new IOSDriver<IOSElement>(
new Uri(""), caps);

// Test case for the sample iOS app.
// If you have uploaded your app, update the test case here.
IOSElement color = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(

IOSElement text = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(

IOSElement toast = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(

IOSElement nf = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(

IOSElement gl = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(



IOSElement st = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(



IOSElement browser = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(

IOSElement inputBox = (IOSElement)new WebDriverWait(driver, TimeSpan.FromSeconds(30)).Until(



Step 5: Configure the Test Capabilities

You can update your custom capabilities in test scripts. In this sample project, we are passing platform name, platform version, device name and app url (generated earlier) along with other capabilities like build name and test name via capabilities object.

The capabilities object in the sample code are defined as:

  AppiumOptions caps = new AppiumOptions(); 
caps.AddAdditionalCapability("LT_USERNAME", "username");
caps.AddAdditionalCapability("LT_ACCESSKEY", "accessKey");
caps.setCapability("platformName", "iOS");
caps.setCapability("deviceName", "iPhone 13 Pro");
caps.setCapability("isRealMobile", true);
caps.setCapability("Visual", true);
caps.setCapability("Console", true);
caps.setCapability("Network", false);


Step 6: Execute and Monitor your Tests

  • Click the Play icon to run the test.

    Your test results would be displayed on the test console (or CLI if you are using terminal/cmd) and on the LambdaTest App Automation Dashboard.
