Aquality Appium Mobile for Java

Build Status Quality Gate Maven Central


This package is a library designed to simplify automation of Android and iOS mobile applications using Appium.

You've got to use this set of methods, related to most common actions performed with web elements.

Most of performed methods are logged using LOG4J, so you can easily see a history of performed actions in your log.

We use interfaces where is possible, so you can implement your own version of target interface with no need to rewrite other classes.

Breaking news!

Starting from v5.0.0 onwards, this package requires Java 11 or higher, as Selenium and Appium have stopped support of Java 8. The last version available for Java 8 is v4.1.1

Quick start

To start the project using framework, you can download our template BDD project by this link.

Alternatively, you can follow the steps below:

  1. Add the dependency to your pom.xml:
  1. Configure the path to your application at settings.json:
  • Copy settings.json into the resources directory of your project.
  • Open settings.json and find applicationPath option under the driverSettings section of desired platform. Replace the value with full or relative path to your app, e.g. ./src/test/resources/apps/ApiDemos-debug.apk.
  1. Ensure that Appium server is set up at your machine where the code would be executed, and the address/port match to set in your settings.json in remoteConnectionUrl parameter. If the parameter isRemote in your settings.json is set to false, this means that AppiumDriverLocalService would be used to set up Appium server using Node.js. This option requires specific version of node.js to be preinstalled on your machine (Please read more here )

Note: After migration to Appium v.8, we started using Appium server v.2 in our azure-pipelines. It has some breaking changes, described here. In particular:

  1. Please install required driver manually:
npm install -g appium@next
appium driver install uiautomator2
  1. As soon as we continue to use "remoteConnectionUrl": "" in our settings.json, we need to specify the --base-path when starting Appium server:
appium --allow-insecure chromedriver_autodownload --base-path /wd/hub &
  1. We also recommend disabling element caching and w3c in chromeOptions when you run Android Chrome session. Take a look at example here: settings.androidwebsession.json.
  1. (optional) Launch an application directly by calling AqualityServices.getApplication();.

Note: If you don't start an Application directly, it would be started with the first call of any Aquality service or class requiring interacting with the Application.

  1. That's it! Now you are able to work with Application via AqualityServices or via element services. Please take a look at our example tests here.

  2. To interact with Application's forms and elements, we recommend following the Page/Screen Objects pattern. This approach is fully integrated into our package. To start with that, you will need to create a separate class for each window/form of your application, and inherit this class from the Screen.

We recommend to use separate Screen class for each form of your application. You can take advantage of inheritance and composition pattern. We also suggest not to mix app different platforms in single class: take advantage of interfaces instead, adding the default implementation to them if it is needed.

  1. From the Screen Object perspective, each Screen consists of elements on it (e.g. Buttons, TextBox, Labels and so on). To interact with elements, on your form class create fields of type IButton, ITextBox, ILabel, and initialize them using the getElementFactory(). Created elements have a various methods to interact with them. We recommend combining actions into a business-level methods:

import org.openqa.selenium.By;

public class InvokeSearchScreen extends Screen {

    private final ITextBox txbSearch = getElementFactory().getTextBox("txt_query_prefill"), "Search");
    private final IButton btnStartSearch = getElementFactory().getButton("btn_start_search"), "Start search");
    private final ILabel lblSearchResult = getElementFactory().getLabel("android:id/search_src_text"), "Search results");

    public InvokeSearchScreen() {
        super(By.xpath("//android.widget.TextView[@text='App/Search/Invoke Search']"), "Invoke Search");

    public void submitSearch(String query) {

    public String getSearchResult() {
        return lblSearchResult.getText();
  1. We use DI Guice to inject dependencies, so you can simply implement your MobileModule extended from MobileModule and inject it to AqualityServices.initInjector(yourModule).


When you automate tests for both iOS and Android platforms it is good to have only one set of tests and different implementations of screens. ScreenFactory allows to do this. You can define abstract classes for your screens and have different implementations for iOS and Android platforms. After that you can use ScreenFactory to resolve a necessary screen depending on the chosen platform.

  1. Set screensLocation property in settings.json. It is a name of package where you define screens.

  2. Define abstract classes for the screens:


import org.openqa.selenium.By;

public abstract class LoginScreen extends Screen {

    private final ITextBox usernameTxb;
    private final ITextBox passwordTxb;
    private final IButton loginBtn;

    protected LoginScreen(By locator) {
        super(locator, "Login");
        usernameTxb = getElementFactory().getTextBox(getUsernameTxbLoc(), "Username");
        passwordTxb = getElementFactory().getTextBox(getPasswordTxbLoc(), "Password");
        loginBtn = getElementFactory().getButton(getLoginBtnLoc(), "Login");

    protected abstract By getUsernameTxbLoc();

    protected abstract By getPasswordTxbLoc();

    protected abstract By getLoginBtnLoc();

    public LoginScreen setUsername(final String username) {
        return this;

    public LoginScreen setPassword(final String password) {
        return this;

    public void tapLogin() {;
  1. Implement interface (Android example):

import org.openqa.selenium.By;

import static io.appium.java_client.AppiumBy.AccessibilityId;
import static org.openqa.selenium.By.xpath;

@ScreenType(platform = PlatformName.ANDROID)
public class AndroidLoginScreen extends LoginScreen {

    public AndroidLoginScreen() {

    protected By getUsernameTxbLoc() {
        return AccessibilityId("username");

    protected By getPasswordTxbLoc() {
        return AccessibilityId("password");

    protected By getLoginBtnLoc() {
        return AccessibilityId("loginBtn");
  1. Resolve screen in test:
public class DemoTest {
    public void testScreenFactory() {
        LoginScreen loginScreen = AqualityServices.getScreenFactory().getScreen(LoginScreen.class);
        Assert.assertNotNull(loginScreen, "Screen must be resolved from factory");


Our library allows you to run tests on different devices and store their settings (like udid, name, etc.) in JSON files.

You have to add devices.json file to resources where you can define a set of devices which you use for the test run.

It is possible to set default device for each platform in settings.json by defining deviceKey property which is a key of device settings from devices.json file.

You can also create several profiles with devices by adding files with suffixes devices.<devicesProfile>.json (like devices.set1.json) and then specify profile using maven args -DdevicesProfile=set1.
