Extensions (Static Methods)

Due to the way we structure our framework, we can create static methods that we can use as extensions on methods involving different object types, such as tapping or long-pressing on a MobileElement, swiping from one element to another, explicitly waiting for an AppiumDriver, or waiting for a MobileElement to be displayed or clickable etc.

MobileElement Extensions

We will begin each method name with ‘me’ (for MobileElement).

meWaitForSeconds() Static Method

Open up the ‘MobileElementExtensions’ class in the ‘utils.extensions’ package and add the following static method for making the Driver wait for a specified number of seconds…

Java

public static WebDriverWait meWaitForSeconds() { WebDriverWait wait = new WebDriverWait(appDriver(), sec); return wait; }

1
2
3
4

public static WebDriverWait meWaitForSeconds() {
WebDriverWait wait = new WebDriverWait(appDriver(), sec);
return wait;
}
Make sure the import for ‘WebDriverWait’ and the static import for appDriver() method have been added above the class…

Java

import org.openqa.selenium.support.ui.WebDriverWait; import static utils.appium.Driver.appDriver;

1
2
3

import org.openqa.selenium.support.ui.WebDriverWait;

import static utils.appium.Driver.appDriver;
Add a static integer variable set to a value of 10 for ‘sec’, and make it private to the class it is in, just above the weWaitForSeconds() method…

Java

private static int sec = 10;

1

private static int sec = 10;

meElementIsDisplayed() Static Method

Add the following static method in the ‘MobileElementExtensions’ class to check that a given MobileElement is displayed, after waiting the specified amount of time from the weWaitForSeconds() method …

public static boolean meElementIsDisplayed(MobileElement element) {
    meWaitForSeconds().until(ExpectedConditions.visibilityOf(element));
    return element.isDisplayed();
}

public static boolean meElementIsDisplayed(MobileElement element) {

meWaitForSeconds().until(ExpectedConditions.visibilityOf(element));

return element.isDisplayed();

}

Also make sure the import for ‘ExpectedConditions’ is added above the class, as well as an import for ‘WebElement’…

Java

import org.openqa.selenium.support.ui.ExpectedConditions; import io.appium.java_client.MobileElement;

1
2

import org.openqa.selenium.support.ui.ExpectedConditions;
import io.appium.java_client.MobileElement;

meElementToBeClickable() Static Method

Add the following static method in the ‘MobileElementExtensions’ class to check that a given MobileElement is clickable, after waiting the specified amount of time from the meWaitForSeconds() method…

public static boolean meElementToBeClickable(MobileElement element) {
    meWaitForSeconds().until(ExpectedConditions.elementToBeClickable(element));
    return element.isEnabled();
}

public static boolean meElementToBeClickable(MobileElement element) {

meWaitForSeconds().until(ExpectedConditions.elementToBeClickable(element));

return element.isEnabled();

}

meTap() Static Method

Add the following static method in the ‘MobileElementExtensions’ class to wait for a given MobileElement to be clickable/tappable, highlight the clickable/tappable MobileElement, and then tap the MobileElement (this is better than simply clicking as on mobile the more realistic action would actually be tapping)…

public static void meTap(MobileElement mobileElement) {
    meElementToBeClickable(mobileElement);
    touchAction.tap(tapOptions().withElement(element(mobileElement))).perform();
}

public static void meTap(MobileElement mobileElement) {

meElementToBeClickable(mobileElement);

touchAction.tap(tapOptions().withElement(element(mobileElement))).perform();

}

For the above to work, we need to add the following static imports…

import static io.appium.java_client.touch.TapOptions.tapOptions;
import static io.appium.java_client.touch.offset.ElementOption.*;

1 2	import static io.appium.java_client.touch.TapOptions.tapOptions; import static io.appium.java_client.touch.offset.ElementOption.*;

We also need to make sure we import the TouchAction class…

import io.appium.java_client.TouchAction;

1	import io.appium.java_client.TouchAction;

We then need to add a a private static TouchAction object in the top of our class (this way we can reuse the TouchAction class in other similar methods)…

private static TouchAction touchAction = new TouchAction(appDriver());

1	private static TouchAction touchAction = new TouchAction(appDriver());

meLongPress() Static Method

Add the following method for long pressing on a Mobile element for two seconds, and then releasing your finger from it…

public static void meLongPress(MobileElement mobileElement) {
        meElementToBeClickable(mobileElement);
        touchAction.longPress(longPressOptions().withElement(element(mobileElement))
                .withDuration(ofSeconds(2))).release().perform();
    }

public static void meLongPress(MobileElement mobileElement) {

meElementToBeClickable(mobileElement);

touchAction.longPress(longPressOptions().withElement(element(mobileElement))

.withDuration(ofSeconds(2))).release().perform();

}

For the above to work, we need to add two more static imports for all Duration methods (* is wildcard for all) and LongPressOptions longPressOptions method…

import static io.appium.java_client.touch.LongPressOptions.longPressOptions;
import static java.time.Duration.*;

1 2	import static io.appium.java_client.touch.LongPressOptions.longPressOptions; import static java.time.Duration.*;

meSwipeFromElementToElement() Static Method

Add the following static method in the ‘MobileElementExtensions’ class to check that the elements to swipe to and from are clickable and highlighted, and then press down on one element and swipe it to another element and then release the finger / touch…

public static void meSwipeFromElementToElement(MobileElement fromMobileElement, MobileElement toMobileElement) {
    meElementToBeClickable(fromMobileElement);
    meElementToBeClickable(toMobileElement);
    touchAction.longPress(longPressOptions().withElement(element(fromMobileElement))
            .withDuration(ofSeconds(2))).moveTo(element(toMobileElement)).release().perform();
}

public static void meSwipeFromElementToElement(MobileElement fromMobileElement, MobileElement toMobileElement) {

meElementToBeClickable(fromMobileElement);

meElementToBeClickable(toMobileElement);

touchAction.longPress(longPressOptions().withElement(element(fromMobileElement))

.withDuration(ofSeconds(2))).moveTo(element(toMobileElement)).release().perform();

}

meSwipeDirection() Static Methods

Add the following DIRECTION enum to the MobileExtensions class…

Java

public enum DIRECTION { DOWN, UP, LEFT, RIGHT; }

1
2
3

public enum DIRECTION {
DOWN, UP, LEFT, RIGHT;
}

Add the following method which uses a switch case with the enum we made to swipe in any given direction…

public static void meSwipe(DIRECTION direction, long duration) {
    Dimension size = appDriver().manage().window().getSize();
    int startX = 0;
    int endX = 0;
    int startY = 0;
    int endY = 0;

    switch (direction) {
        case RIGHT:
            startY = (int) (size.height / 2);
            startX = (int) (size.width * 0.90);
            endX = (int) (size.width * 0.05);
            new TouchAction(appDriver())
                    .press(PointOption.point(startX, startY))
                    .waitAction(WaitOptions.waitOptions(Duration.ofMillis(duration)))
                    .moveTo(PointOption.point(endX, startY))
                    .release()
                    .perform();
            break;

        case LEFT:
            startY = (int) (size.height / 2);
            startX = (int) (size.width * 0.05);
            endX = (int) (size.width * 0.90);
            new TouchAction(appDriver())
                    .press(PointOption.point(startX, startY))
                    .waitAction(WaitOptions.waitOptions(Duration.ofMillis(duration)))
                    .moveTo(PointOption.point(endX, startY))
                    .release()
                    .perform();
            break;

        case UP:
            endY = (int) (size.height * 0.70);
            startY = (int) (size.height * 0.30);
            startX = (size.width / 2);
            new TouchAction(appDriver())
                    .press(PointOption.point(startX, startY))
                    .waitAction(WaitOptions.waitOptions(Duration.ofMillis(duration)))
                    .moveTo(PointOption.point(endX, startY))
                    .release()
                    .perform();
            break;

        case DOWN:
            startY = (int) (size.height * 0.70);
            endY = (int) (size.height * 0.30);
            startX = (size.width / 2);
            new TouchAction(appDriver())
                    .press(PointOption.point(startX, startY))
                    .waitAction(WaitOptions.waitOptions(Duration.ofMillis(duration)))
                    .moveTo(PointOption.point(startX, endY))
                    .release()
                    .perform();
            break;
    }
}

public static void meSwipe(DIRECTION direction, long duration) {

Dimension size = appDriver().manage().window().getSize();

int startX = 0;

int endX = 0;

int startY = 0;

int endY = 0;

switch (direction) {

.waitAction(WaitOptions.waitOptions(Duration.ofMillis(duration)))

.moveTo(PointOption.point(endX, startY))

.release()

.perform();

break;

case LEFT:

startY = (int) (size.height / 2);

    meElementIsDisplayed(element);
    if (clearFirst) meTap(element);
    element.sendKeys(text);
}

1
2
3

public static String meGetAttribute(MobileElement element, String attribute) {
return element.getAttribute(attribute);
}

Espresso Specific Mobile Commands

Espresso is an Android test automation library maintained by Google. It has a number of advantages, for example built-in view synchronisation that ensures element finding happens during idle periods in your app.

We can use Espresso framework with our Appium driver when running tests. Espresso contains certain mobile commands / gestures which are specific to the framework. The ‘EspressoExtensions’ class will contain static methods for each of these Espresso specific mobile commands.

First things first, let’s make this ‘EspressoExtensions’ class extend ‘MobileElementExtensions’ class and also add a private static AndroidDriver variable and set it to what’s returned from our ‘appDriver()’ method (making sure we add the correct static import), like below…

package utils.extensions;

import io.appium.java_client.android.AndroidDriver;

import static utils.appium.Driver.appDriver;

public class EspressoExtensions extends MobileElementExtensions {

    private static AndroidDriver driver = appDriver();
}

package utils.extensions;

import io.appium.java_client.android.AndroidDriver;

import static utils.appium.Driver.appDriver;

public class EspressoExtensions extends MobileElementExtensions {

private static AndroidDriver driver = appDriver();

}

We will being each method name with ‘es’ (as it is specific to Espresso mobile gestures).

    driver.executeScript("mobile: swipe", params);
}

public static void esSwipe(String direction) {

Map<String, Object> params = new HashMap<>();

params.put("direction", direction);

driver.executeScript("mobile: swipe", params);

}

Also make sure the following imports are added…

Java

WebDriver Extensions

We will begin each method name with ‘wd’ (for WebDriver).

wdHighlight() Static Method

Open up the ‘WebDriverExtensions’ class in the ‘utils.extensions’ package and add the following static method for highlighting a given locator using JavaScript…

public static Object wdHighlight(By locator) {
    WebDriver driver = appDriver();
    WebElement myLocator = driver.findElement(locator);
    JavascriptExecutor js = (JavascriptExecutor) appDriver();
    return js.executeScript(wdHighlightedColour, myLocator);
}

public static Object wdHighlight(By locator) {

WebDriver driver = appDriver();

WebElement myLocator = driver.findElement(locator);

JavascriptExecutor js = (JavascriptExecutor) appDriver();

return js.executeScript(wdHighlightedColour, myLocator);

}

You will notice that an error is thrown due to not knowing what ‘wdHighlightedColour’ is, so let’s add that in the ‘Settings’ class of the ‘utils.selenium’ package (of course you can also customise this to change the colour and size of the border etc.)…

public static String wdHighlightedColour = "arguments[0].style.border='5px solid blue";

1

public static String wdHighlightedColour = "arguments[0].style.border='5px solid blue";
Next, go back to the ‘WebDriverExtensions’ class and add a static import for ‘wdHighlightedColour’ in the ‘Settings’ class…

Java

import static utils.appium.Settings.wdHighlightedColour;

1

import static utils.appium.Settings.wdHighlightedColour;

Of course, also check that the imports for ‘WebDriver’, ‘WebElement’, ‘JavaScriptExecutor’ and ‘By’ have been added above the class, as well as a static import again for the browser() method in the ‘Drivers’ class of the ‘utils.selenium’ package…

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import static utils.appium.Driver.appDriver;

import org.openqa.selenium.By;

import org.openqa.selenium.JavascriptExecutor;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import static utils.appium.Driver.appDriver;

wdElementIsDisplayed() Static Method

Open up the ‘WebDriverExtensions’ class in the ‘utils.extensions’ package and add the following static method for checking that a highlighted locator is displayed…

public static Object wdElementIsDisplayed(By locator) {
    wdHighlight(locator);
    WebDriverWait wait = new WebDriverWait(appDriver(), sec);
    return wait.until(ExpectedConditions.visibilityOf((WebElement) locator));
}

public static Object wdElementIsDisplayed(By locator) {

wdHighlight(locator);

WebDriverWait wait = new WebDriverWait(appDriver(), sec);

return wait.until(ExpectedConditions.visibilityOf((WebElement) locator));

}

Make sure the import for ‘WebDriverWait’ and ‘ExpectedConditions’ have been added above the class…

Java

import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait;

1
2

import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
Add a static integer variable set to a value of 10 for ‘sec’, and make it private to the class it is in, just above the weWaitForSeconds() method…

Java

private static int sec = 10;

1

private static int sec = 10;

wdElementIsInvisible() Static Method

Add the following static method in the ‘WebDriverExtensions’ class to wait for a given locator to not be visible…

public static void wdElementToDisappear(By locator) {
    WebDriverWait wait = new WebDriverWait(appDriver(), 5);
    wait.until(ExpectedConditions.invisibilityOfElementLocated(locator));
}

public static void wdElementToDisappear(By locator) {

WebDriverWait wait = new WebDriverWait(appDriver(), 5);

wait.until(ExpectedConditions.invisibilityOfElementLocated(locator));

}

wdFindElement() Static Method

Add the following static method in the ‘WebDriverExtensions’ class to find a displayed element by its locator…

Java

public static WebElement wdFindElement(By locator) { wdElementIsDisplayed(locator); return appDriver().findElement(locator); }

1
2
3
4

public static WebElement wdFindElement(By locator) {
wdElementIsDisplayed(locator);
return appDriver().findElement(locator);
}

wdClick() Static Method

Add the following static method in the ‘WebDriverExtensions’ class to click on an element which has been found by its locator…

Java

public static void wdClick(By locator) { wdFindElement(locator).click(); }

1
2
3

public static void wdClick(By locator) {
wdFindElement(locator).click();
}

wdSendKeys() Static Method

Add the following static method in the ‘WebDriverExtensions’ class to wait for a given textfield element (which has been found by its locator) to be displayed, clear the textfield if necessary (if ‘clearFirst’ is true), and then input a given String into the textfield…

public static void wdSendKeys(By locator, String text, boolean clearFirst) {
    if (clearFirst) wdClick(locator);
    wdFindElement(locator).sendKeys(text);
}

Refactoring our Test Scenario to use the Extensions

We can now use our extensions (static methods) to replace previous lines of code in our test methods. Over time, this helps us follow DRY principles (Don’t Repeat Yourself) as well as make our code easier to read 🙂

‘skipWelcomeScreen()’ method

Open up the ‘NavigationScenarios.feature’ file, right-click on the ‘And the welcome screen is skipped without logging in’ step, and select ‘Go To’ –> ‘Declaration’
Right-click on the ‘.skipWelcomeScreen()’ method call and select ‘Go To’ –> ‘Declaration’ again

Edit the ‘skipWelcomeScreen()’ method so it uses the meTap() static method from the ‘MobileElementExtensions’ class (you will have to add a static import to access all the static methods in the MobileElementExtensions class)…

import static utils.extensions.MobileElementExtensions.*;

1	import static utils.extensions.MobileElementExtensions.*;

public PopularTabPage skipWelcomeScreen() {
    meTap(btnSkipForNow);
    log.info(":: We click the 'Skip For Now' button on the Welcome screen");
    return instanceOf(PopularTabPage.class);
}

public PopularTabPage skipWelcomeScreen() {

meTap(btnSkipForNow);

log.info(":: We click the 'Skip For Now' button on the Welcome screen");

return instanceOf(PopularTabPage.class);

}

‘navToHomeTab()’ method

Open up the ‘NavigationScenarios.feature’ file again, right-click on the ‘When I view the Home tab’ step, and select ‘Go To’ –> ‘Declaration’
Right-click on the ‘.navToHomeTab()’ method call and select ‘Go To’ –> ‘Declaration’ again

Edit the ‘navToHomeTab()’ method so it uses the meTap() static method from the ‘MobileElementExtensions’ class again (you will have to add a static import to access all the static methods in the MobileElementExtensions class)…

import static utils.extensions.MobileElementExtensions.*;

1	import static utils.extensions.MobileElementExtensions.*;

public HomeTabPage navToHomeTab() {
    meTap(homeTab);
    log.info(":: We navigate to the 'Home' tab");
    return instanceOf(HomeTabPage.class);
}

public HomeTabPage navToHomeTab() {

meTap(homeTab);

log.info(":: We navigate to the 'Home' tab");

return instanceOf(HomeTabPage.class);

}

Running the Test Scenario

Running the Test

Open up ‘NavigationScenarios.feature’ file and make sure you have the ‘@Nexus5xOreo’ tag at the top of the feature file or above each test scenario you want to run
Right-click on the test scenario and run it

It should pass 😀
