Kotlin With Appium

Tutorial To Run Your First Test On LambdaTest​

In this topic, you will learn how to configure and run your Kotlin automation testing scripts with Appium on LambdaTest Real Device Cloud platform.

Objective​

By the end of this topic, you will be able to:

  1. Run a sample automation script of Kotlin for application testing with Appium on LambdaTest.
  2. Learn more about Desired Capabilities for Appium testing.
  3. Explore advanced features of LambdaTest.
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

Pre-requisites​

Before you start performing App automation testing with Appium, you would need to follow these steps::

  • You need to install the latest version of IntelliJ IDEA because it provides Kotlin support. It is recommended by us but you can use any other IDE also.
  • Make sure that Kotlin plugins are enabled/installed in the IntelliJ IDEA if you are using a previous version.
  • Download and install Maven following the steps from the official website. Maven can also be installed easily on Linux/MacOS using Homebrew package manager.
  • Make sure that you have access to LambdaTest username and accessKey. If you have not registered yet, you can do the same by visiting our website. You will be able to access the credentials in the LambdaTest Profile

Run your first test​

1. Upload your application​

Upload your iOS application (.ipa file) or android application (.apk 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. Here is an example cURL request to upload your app using our REST API:

Using App File from System:

curl -u "undefined:undefined" -X POST "https://manual-api.lambdatest.com/app/upload/realDevice" -F "appFile=@"/Users/macuser/Downloads/proverbial_android.apk"" -F "name="proverbial_app""

Using App URL:

curl -u "undefined:undefined" -X POST "https://manual-api.lambdatest.com/app/upload/realDevice" -F "url=:https://prod-mobile-artefacts.lambdatest.com/assets/docs/proverbial_android.apk" -F "name=Proverbial_App"
tip

  • If you do not have any .apk or .ipa file, you can run your sample tests on LambdaTest by using our sample 🔗 Android app or sample 🔗 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.

2. Clone the sample project​

  1. Clone the LambdaTest’s 🔗 LT-appium-java repository:
git clone https://github.com/LambdaTest/LT-appium-java
  1. After you have cloned the project file open it in InjelliJ IDEA as a Maven project.
  2. Now right click on the LT-appium-kolin in the side bar under Projects, go to Mark directory as and choose it as Source root.

3. Set up your authentication​

Make sure you have your LambdaTest credentials with you to run test automation scripts on LambdaTest. To obtain your access credentials, purchase a plan or access the Automation Dashboard. Then, set LambdaTest Username and Access Key in environment variables with following commands.

export LT_USERNAME=undefined \
export LT_ACCESS_KEY=undefined

4. Write your automation script​

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

android.kt
import io.appium.java_client.MobileBy
import io.appium.java_client.MobileElement
import io.appium.java_client.android.AndroidDriver
import io.appium.java_client.android.AndroidElement
import org.junit.jupiter.api.Test
import org.openqa.selenium.remote.DesiredCapabilities
import java.net.URL

class android {

    @Test
    fun `sample test`() {
        val username = "LT_USERNAME"   //Add your LambdaTest username here
        val accessKey = "LT_ACCESS_KEY"    //Add your LambdaTest accessKey here

        var driver: AndroidDriver<MobileElement>? = null

        val hub = URL("https://${username}:${accessKey}@mobile-hub.lambdatest.com/wd/hub")

        val caps = DesiredCapabilities()
        caps.setCapability("autoAcceptAlerts", true)
        caps.setCapability("platformName", "Android")
        caps.setCapability("deviceName", "Galaxy S20")
        caps.setCapability("platformVersion", "11")
        caps.setCapability("platformName", "Android")
        caps.setCapability("isRealMobile", true)
        caps.setCapability("app", "APP_URL") //Add the app (.apk) url here
        caps.setCapability("deviceOrientation", "PORTRAIT")
        caps.setCapability("build", "Kotlin Vanilla - Android")
        caps.setCapability("name", "Sample Test Kotlin")
        caps.setCapability("console", true)
        caps.setCapability("network", false)
        caps.setCapability("visual", true)
        caps.setCapability("device log", true)


        val app = AndroidDriver<AndroidElement>(hub, caps)

        Thread.sleep(4000)

        val color: MobileElement =
            app.findElement(MobileBy.id("com.lambdatest.proverbial:id/color")) as MobileElement
            color.click()

        val text: MobileElement =
            app.findElement(MobileBy.id("com.lambdatest.proverbial:id/Text")) as MobileElement
            text.click()

        val toast: MobileElement =
            app.findElement(MobileBy.id("com.lambdatest.proverbial:id/toast")) as MobileElement
            toast.click()

        val notification: MobileElement =
            app.findElement(MobileBy.id("com.lambdatest.proverbial:id/notification")) as MobileElement
            notification.click()

        val geo: MobileElement =
            app.findElement(MobileBy.id("com.lambdatest.proverbial:id/geoLocation")) as MobileElement
            geo.click()
        Thread.sleep(5000)

        val el3: MobileElement =
            app.findElementByAccessibilityId("Home") as MobileElement

        app.navigate().back()
        Thread.sleep(2000)

        val speedtest: MobileElement =
            app.findElement(MobileBy.id("com.lambdatest.proverbial:id/speedTest")) as MobileElement
            speedtest.click()
        Thread.sleep(5000)

        app.navigate().back()


        if (app != null) {
            app.quit()
        };

    }
}

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:

        val caps = DesiredCapabilities()
        caps.setCapability("platformName", "ios")
        caps.setCapability("deviceName", "iPhone 12")
        caps.setCapability("platformVersion", "14")
        caps.setCapability("isRealMobile", true)
        caps.setCapability("app", "APP_URL") //Add the app (.ipa) url here
        caps.setCapability("deviceOrientation", "PORTRAIT")
        caps.setCapability("build", "Kotlin Vanilla - iOS")
        caps.setCapability("name", "Sample Test Kotlin")
        caps.setCapability("console", true)
        caps.setCapability("network", false)
        caps.setCapability("visual", true)
        caps.setCapability("device log", true)
Note

5. Execute your test case​

  1. Run the following commands to install the required dependencies:
mvn clean install
  1. Firstly build the test in IntelliJ IDEA and make sure that it is build successfully.
  2. Then, try running the current file by using Run button in the IDE.
info

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