if-else语句不适用于Appium Java代码

Question

I have written a Java code with if-else statements and user would move from 'Screen1' to 'Screen2' through any of 4 alternate routes and I have attached an image for all possible application flows which are decided on the go by of course code written by developer. Just to add tool used is Appium.

    driver.findElement(By.id("----")).click(); //this click will take from  'screen1' to next screen.
          if(driver.findElement(By.id("com.abc.rbanking:id/WhatsNew")).isDisplayed())
    { //case if screen A is displayed just after screen 1
        MobileElement cross = driver.findElement(By.xpath("//*[@class = 'android.widget.ImageView']"));
        cross.click();

        Thread.sleep(3000);

    }

    if(driver.findElement(By.xpath("//android.widget.TextView[@resource-id='com.abc.rbanking:id/text_logo'][text()='Security Question']")).isDisplayed())
    { //case when screen B is displayed Just after screen 1

    MobileElement mfaQ = driver.findElement(By.id("com.abc.rbanking:id/MfaQuestionText"));
    String question = mfaQ.getText();

    String lastword = question.replaceAll("^.*?(\\w+)\\W*$", "$1");

    System.out.println(lastword);

    MobileElement answer = driver.findElement(By.id("com.abc.rbanking:id/MfaAnswerTextBox"));

    answer.sendKeys(lastword);

    MobileElement checkbox = driver.findElement(By.id("com.abc.rbanking:id/ShowChallengeAnswerCheckbox"));
    checkbox.click();

    Thread.sleep(3000);

    MobileElement nextb = driver.findElement(By.id("com.abc.rbanking:id/PrimaryButton"));
    nextb.click();

    Thread.sleep(8000);
    }

    if(driver.findElement(By.id("com.abc.rbanking:id/WhatsNew")).isDisplayed())
    { //case when screen A is displayed after screen B
        MobileElement cross = driver.findElement(By.xpath("//*[@class = 'android.widget.ImageView']"));
        cross.click();
        Thread.sleep(3000);
    }


         driver.findElement(By.id("----")); //this is code for 'Screen 2'

What happens is during execution of script, first 'If' is checked and rest all code skipped. I am not able to figure out the issue. Please help.

Answer 1

It sounds here as if (no pun intended) you actually don't want an if else construct. So try just using separate if statements:

// see if element on 'screen A' is displayed
if (driver.findElement(By.id("abc")).isDisplayed()) {
    //execute a few statements

}

// see if element on 'Screen B' is displayed
if (driver.findElement(By.id("xyz")).isDisplayed()) {

   // execute a few statements
}

// see if element on 'screen A' is displayed
if (driver.findElement(By.id("abc")).isDisplayed()) {

}
driver.findElement(By.id("----")); //this is code for 'Screen 2'

The behavior your describe, namely with the first if being hit and nothing else executing, is precisely how your code should behave. If you intend to allow for each block of code to possibly execute, then what I gave above is one option.

Finally I am able to find a solution for the problem and it is working fine. I put if statement in try-catch block like in below code and it works perfectly fine for every alternative posed by application to the end user.

try {
            if (driver.findElement(By.xpath("//android.widget.TextView[@resource-id='com.abc.rbanking:id/text_logo'][text()='Security Question']")).isDisplayed()) { //case when screen B is displayed Just after screen 1
                MobileElement mfaQ = driver.findElement(By.id("com.abc.rbanking:id/MfaQuestionText"));
                String question = mfaQ.getText();
                String lastword = question.replaceAll("^.*?(\\w+)\\W*$", "$1");
                System.out.println(lastword);
                MobileElement answer = driver.findElement(By.id("com.abc.rbanking:id/MfaAnswerTextBox"));
                answer.sendKeys(lastword);
                MobileElement checkbox = driver.findElement(By.id("com.abc.rbanking:id/ShowChallengeAnswerCheckbox"));
                checkbox.click();
                Thread.sleep(3000);
                MobileElement nextb = driver.findElement(By.id("com.abc.rbanking:id/PrimaryButton"));
                nextb.click();
                Thread.sleep(8000);
            }
        } catch (
                Exception e) {
            e.printStackTrace();
        }
        try

        {
            if (driver.findElement(By.id("com.abc.rbanking:id/WhatsNew")).isDisplayed()) { //case when screen A is displayed after screen B
                MobileElement cross = driver.findElement(By.xpath("//*[@class = 'android.widget.ImageView']"));
                cross.click();
                Thread.sleep(3000);
            }
        } catch (
                Exception e)

        {
            e.printStackTrace();
        }
    }
