Issues
• Stability issues
• Actions depends on platform
• Problems with accessing some elements
• iOS specific issues
– Single app test
– Hardware keys support
– One emulator instance
– xpath

Web apps
• Similar layouts
• Same locators
• Absolutely the same tests can be executed
• Not require additional efforts
Native apps
• Different layout
• Different locators
• Platform specific UI elements
• Test cases should be specially designed
• Require additional efforts

Tests
• Test steps should be similar for both platforms
@Test (dataProvider = "Logins")
@Features ("Login")
@Stories ("User should not be able to login with incorrect credentials")
public void verify_Incorrect_Login(Map<String, String> testData){
loginScreen.verifyScreenLoaded();
loginScreen.submitLogin(testData.get("User"),testData.get("Password"));
loginScreen.verifyAndCloseErrorMessage(testData.get("Message"));
loginScreen.verifyScreenLoaded();
}
Page Objects
• Do not hardcode locators in Page objects
• Store it in external object
• Implement platform specific code
• Create bindings for platform specific actions
Page Object
public class LoginScreen extends Bindings {
public LoginScreen(Instance instance) {super(instance);initLocators();
}
private static String LoginScreenUserField;private static String LoginScreenPasswordField;private static String LoginScreenSubmitLoginBtn;private static String LoginScreenErrorMsg;private static String LoginScreenErrorMsgCloseBtn;
private void initLocators() {
LoginScreenUserField = locators.get("LoginScreenUserField");LoginScreenPasswordField = locators.get("LoginScreenPasswordField");LoginScreenSubmitLoginButton = locators.get("LoginScreenSubmitLoginButton");LoginScreenErrorMsg = locators.get("LoginScreenErrorMsg");LoginScreenErrorMsgCloseBtn = locators.get("LoginScreenErrorMsgCloseBtn");
}... ...
Page Object
@Steppublic void submitLogin(String login, String pass) {
typeKeys(LoginScreenUserField, login);typeKeys(LoginScreenPasswordField, pass);tap(LoginScreenSubmitLoginBtn);
}
@Steppublic void verifyAndCloseErrorMessage(String Message) {
verifyElementPresent(LoginScreenErrorMsg);assetEqual(getText(LoginScreenErrorMsg),Message);
if (instance.getPlatform().equals("ios"))tap(LoginScreenErrorMsgCloseBtn);elseclickBackBtn();
}
Locators
<?xml version='1.0' encoding='UTF-8'?><dataset><LOCATORNAME="LoginScreenUserField" ANDROID="id=com.example.myapp:id/txtUser"IOS="xpath=//window[1]/textfield[1]"/>
<LOCATORNAME="LoginScreenPasswordField" ANDROID="id=com.example.myapp:id/txtPassword"IOS="xpath=//window[1]/textfield[2]"/>
<LOCATORNAME="LoginScreenSubmitLoginButton" ANDROID="name=Login " IOS="name=Login"/>
<LOCATORNAME="LoginScreenErrorMsg" ANDROID="id=com.example.myapp:id/errText" IOS="xpath=//*/UIAPopover[contains(@name,'ErrorText')]"/>
<LOCATORNAME="LoginScreenErrorMsgCloseBtn" IOS="name=Ok"/>
