How to “wait to activity” using Appium, on begin and during test itself?

Question

I\'m starting an already installed app using appium.

After my driver is initialized. How do I make it poll-wait till certain activity is displayed?

I saw onl

Answer 1

Specific activity means some specific element is being displayed. I use the following code to wait until some certain element on the screen:

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.elementToBeClickable(By
        .xpath("//android.widget.Button[contains(@text, 'Log In')]")));

or:

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.presenceOfElementLocated(By
            .xpath("//android.widget.TextView[contains(@resource-id, 'action_bar_title')]")));

Answer 2

It can be done by different ways using element. Webdriver provide “WebDriverWait”, “ExpectedCondition” classes to implement this. ExpectedConditions class provide some set of predefine conditions to wait elements as:

1. elementSelectionStateToBe: an element state is selection.
2. elementToBeClickable: an element is present and clickable.
3. elementToBeSelected: element is selected
4. frameToBeAvailableAndSwitchToIt: frame is available and frame
5. selected. invisibilityOfElementLocated: an element is invisible
6. presenceOfAllElementsLocatedBy: present element located by.
7. refreshed: wait for a particular condition when page refresh.
8. textToBePresentInElement: text present on particular an element
9. textToBePresentInElementValue: and element value present for a
   particular element. and many more You can learn more ways to implement implicit and explicit wait by going through this url: http://roadtoautomation.blogspot.in/2013/10/webdriver-implicit-and-explicit-wait.html

Hope it helps...

Answer 3

I would suggest you to use WebDriverWait. Thread.sleep() is not a good way to use in your test scripts

Answer 4

long startTime = System.currentTimeMillis();
while(System.currentTimeMillis() - startTime < Time_Out)
    if (getDriver().currentActivity().equals(activity))
        break;

Answer 5

You can use the following code to poll the current activity every second. If you want to reduce polling time you can reduce sleep time to 500 and wait*2 :

public void waitForActivity(String desiredActivity, int wait) throws InterruptedException
{
    int counter = 0;
    do {
        Thread.sleep(1000);
        counter++;
    } while(driver.currentActivity().contains(desiredActivity) && (counter<=wait));

    log("Activity appeared :" + driver.currentActivity(), true);
}

Answer 6

WebDriverWait wait = new WebDriverWait(driver,20);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("about_me")));
