我们可以在 Appium (Android) 中使用 PageFactory.initElements

Question

尝试使用 Appium 在移动自动化中使用时遇到异常。虽然它非常适合 Web 测试自动化。

*Given The app is opened                                                      # CommonSteps.OpenApp()
    Then I should see "Skip button" on welcome screen                            # WelcomeScreenSteps.CheckElementPresent(String)

我们可以在 Appium Mobile 自动化中使用 PageFactory.initElements 吗？

功能文件：

Feature: As a user, I want to open the app when not logged in and check the welcome screens
@TestTag
Scenario: Open app when not logged in and check 3 welcome screens using swipes
Given The app is opened
Then I should see "Skip button" on welcome screen

步骤文件：

public class WelcomeScreenSteps extends DriverStore {

    // WebDriver driver = new FirefoxDriver();
    Pages pages = PageFactory.initElements(driver, Pages.class);
    //WelcomeSreenPage welcomeScreen = new WelcomeSreenPage(driver);

    public WelcomeScreenSteps() {
        // System.out.println("I am in Welcome Constructor");
    }
@Given("^the app is open$")
    public void the_app_is_open() throws Throwable {
        // Code to open the app
        System.out.println("in the step");
    }
@Then("^I should see \"(.*?)\" on welcome screen$")
    public void CheckElementPresent(String identifire) {
        Assert.assertTrue(pages.welcomeScreen.checkElementPresent(identifire));
    }

Pages.java

public class Pages {
    /*AppiumDriver driver;*/
    static AppiumDriver driver;

    public WelcomeSreenPage welcomeScreen = PageFactory.initElements(driver, WelcomeSreenPage.class);

    /*public Pages(AppiumDriver driver) {
        this.driver = driver;
    }*/
    public Pages(AppiumDriver driver) {
        Pages.driver = driver;
    }

    public WelcomeSreenPage welcomeScreen() {
        welcomeScreen = new WelcomeSreenPage(driver);
        return welcomeScreen;
    }
}

WelcomeScreenPage.java

public class WelcomeSreenPage {
// all mobile element identifier here
    // WebDriver driver;
    AppiumDriver driver;
public boolean checkElementPresent(String identifire) {
        MobileElement element = actions.getElement(mapElement(identifire),
                driver);
        if (element != null)
            return true;
        else
            return false;
    }

This Working with Me、My Project Selenium、TestNG 和 Appium 使用 PageFactory.initElements

public class Login extends Setup {

    @Test
    public void loginAlert() throws InterruptedException {
        

    Button button = new Button(driver);
            PageFactory.initElements(driver, button);
            Input input = new Input(driver);
            PageFactory.initElements(driver, input);
        
        
        Input input1 = new Input(driver);
        System.out.println("Test Alert Login");
        button.ById("navigation_more");
        button.ById("btnLogin");
        input.ById("et_email_or_phone_number", "dikakoko.com");
        input1.ById("tet_password", "dikakoko");
        
    }
}

下面是我上面调用的函数。

public class Input {
    AppiumDriver<MobileElement> driver;
    Root root = new Root();

    public Input(AppiumDriver<MobileElement> driver) {
        this.driver = driver;
    }

    public void ById(String selector, String textValue) {
        MobileElement element = driver.findElement(By.id(root.element() + ":id/" + selector));
        waitForVisible(driver, element);
        Actions actions = new Actions(driver);
        actions.moveToElement(element);
        actions.click();
        actions.sendKeys(textValue);
        actions.build().perform();
        System.out.println("Input: " + textValue);
    }
    
    private void waitForVisible(AppiumDriver<MobileElement> driver, MobileElement element) {
        try {
            Thread.sleep(5000);
            System.out.println("Waiting for element visibility");
            WebDriverWait wait = new WebDriverWait(driver, 20);
            wait.until(ExpectedConditions.visibilityOf(element));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

还有这个

public class Button {

    AppiumDriver<MobileElement> driver;
    Root root = new Root();

    public Button(AppiumDriver<MobileElement> driver) {
        this.driver = driver;
    }

    public void ById(String selector) {
        MobileElement element = driver.findElement(By.id(root.element() + ":id/" + selector));
        Actions actions = new Actions(driver);
        actions.moveToElement(element);
        actions.click();
        actions.build().perform();
        System.out.println("Button is Clicked!");
    }
}

我用这个

Button button = new Button(driver);
PageFactory.initElements(driver, button);
Input input = new Input(driver);
PageFactory.initElements(driver, input);
