if-else语句不适用于Appium Java代码

Question

我已经用if-else语句编写了Java代码，并且用户将通过4条替代路线中的任何一条从“ Screen1”移到“ Screen2”，并且我为所有附加图像 可能的应用程序流程由开发人员编写的代码随时随地决定。 只是增加使用的工具是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'

发生的情况是在脚本执行期间，首先检查“ If”，然后跳过所有代码。 我无法解决问题。 请帮忙。

Answer 1

在这里听起来好像（实际上不是双关语）您实际上不需要 if else构造。 因此，尝试仅使用单独的if语句：

// 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'

你的描述，即与第一行为if被击中，没有别的执行，恰恰是你的代码应该如何表现。 如果您打算允许每个代码块都可以执行，那么我上面给出的是一个选择。

最后，我能够找到该问题的解决方案，并且工作正常。 我将if语句放在try-catch块中，如下面的代码所示，它对于应用程序对最终用户提出的每个替代方案都非常适用。

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();
        }
    }
