  • Include %ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools;%ANDROID_HOME%\platforms; in PATH variable.

SDK Manager:

The Android SDK separates tools, platforms, and other components into packages you can download using the SDK Manager. For example, when the SDK Tools are updated or a new version of the Android platform is released, you can use the SDK Manager to quickly download them to your environment.

You can launch the SDK Manager in one of the following ways:
    • From Eclipse (with ADT), select Window > Android SDK Manager.
    • On Windows, double-click the SDK Manager.exe file at the root of the Android SDK directory.
  • You can select which packages you want to download by toggling the checkboxes on the left, then click Install to install the selected packages.




AVD Manager:

An Android Virtual Device (AVD) is a device configuration that is run with the Android emulator. It works with the emulator to provide a virtual device-specific environment in which to install and run Android apps.
You can launch the AVD Manager in one of the following ways
  • Run SDK Manager and select Manage AVDs from the Tools menu.
  • From eclipse you can click on AVD Manager.




    Creating the AVD:

  • Android Virtual Device Manager lets you create, update, delete, repair, and start AVDs

  • Click the New button to create a new AVD and give the AVD details


  • After creating the AVD , you could see the following screen


3. Appium Installation:

You can install the appium in two ways

Appium: Remote Execution (Grid Execution)












Appium: Remote Execution (Grid Execution)


Source for this post: official github page

Selenium Grid

You are able to register your appium server with a local Selenium grid (setup docs) by using the --nodeconfig server parameter.
> appium --nodeconfig /path/to/nodeconfig.json
# or, if running from source:
> node . --nodeconfig /path/to/nodeconfig.json
In the node config file you have to define the browserNameversion and platform and based on these parameters the grid will re-direct your test to the right device. You will also need to configure your host details and the selenium griddetails. For a full list of all parameters and descriptions look here
Once you start the appium server and it registers with the grid, you will see your device on the grid console page:
"http://<grid-ip-adress>:<grid-port>/grid/console"

Grid Node Configuration Example json file

{
  "capabilities":
      [
        {
          "browserName": "<e.g._iPhone5_or_iPad4>",
          "version":"<version_of_iOS_e.g._7.1>",
          "maxInstances": 1,
          "platform":"<platform_e.g._MAC_or_ANDROID>"
        }
      ],
  "configuration":
  {
    "cleanUpCycle":2000,
    "timeout":30000,
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "url":"http://<host_name_appium_server_or_ip-address_appium_server>:<appium_port>/wd/hub",
    "host": <host_name_appium_server_or_ip-address_appium_server>,
    "port": <appium_port>,
    "maxSession": 1,
    "register": true,
    "registerCycle": 5000,
    "hubPort": <grid_port>,
    "hubHost": "<Grid_host_name_or_grid_ip-address>"
  }
}
Valid platforms are listed here
If urlhost, and port are not given, the config will be auto updated to point to localhost:whatever-port-Appium-started-on.
If your Appium server is running on a different machine to your Selenium Grid server, make sure you use an external name/IP address in your host & url docs; localhost and 127.0.0.1 will prevent Selenium Grid from connecting correctly.

Sample nodeconfig.json

{
"capabilities":
[
{
"browserName": "",
"version":"",
"maxInstances": 1,
"platform":"ANDROID"
}
],
"configuration":
{
"cleanUpCycle":2000,
"timeout":30000,
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"url":"http://172.20.67.130:4723/wd/hub",
"host":"172.20.67.130",
"port": 4723,
"maxSession": 1,
"register": true,
"registerCycle": 5000,
"hubPort": 4444,
"hubHost": "172.20.68.161"
}
}
Note:

copy your config file to the http://www.jsoneditoronline.org/ ,it will show you the location of syntax error

Appium: Connecting Android device through WIFI




We can execute the test cases using either Appium or Calabash by connecting android device to Wi-Fi.

Following are the steps to Connect Android device through WIFI



Prerequisite:


Android SDK is installed.
Connect your device to your PC as usual via usb
Device and Automation Box connected to same WiFI

  • $ adb tcpip 5555 –>This will restart adb and make it work over tcpip.

Disconnect your device now
Ensure that your phone is connected to the same wifi network as your PC.
Get the IP address of your phone (“Settings" -> Wifi -> “Your connected network” -> Your IP address will be shown here)
Run the ‘adb connect’ command

  • $ adb connect <your phones ip address>

You are now connected.
To verify that adb has indeed connected successfully, run -

  • $ adb devices

If it shows your device, then you are good to go with either appium or calabash

Selenium WebDriver : How to TakeScreenshot Of WebElement



Selenium WebDriver : How to TakeScreenshot Of WebElement




Every one know that it is possible to take the screenshot of page using Selenium, but most of the people doesn't that there is a possibility for taking the screen of WebElement also....!, you might have a doubt what is the use of taking the screen shot of the element ?

One of the interesting answer is for comparing the images, Surprised.....! but it is possible compare the images using Selenium WebDriver
Here we go.....:)

                   http://qaautomationworld.blogspot.in/

          Selenium WebDriver : How to TakeScreenshot Of WebElement

1. Taking the screen shot of the page. Every selenium automation engineer know it... :)
WebDriver driver = new FirefoxDriver();
driver.get("http://qaautomationworld.blogspot.in/");
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File("c:\\qaautomationworld\\qaautomationworld.png"));

2. Taking the screen shot of particular WebElement

    
  •  Grab full-page screenshot
  •  Get WebElement position
  •  Get WebElement dimension
  •  Crop WebElement image from page screenshot
  • Save WebElement image to disk

 WebDriver driver = new FirefoxDriver();
 driver.get("http://qaautomationworld.blogspot.in/");
 WebElement element = driver.findElement(By.xpath("//img[@alt='Selenium WebDriver Tips']"));
 WrapsDriver wrapsDriver = (WrapsDriver) element;
 //Get the entire Screenshot from the driver of passed WebElement
 File screen = ((TakesScreenshot) wrapsDriver.getWrappedDriver()).
 getScreenshotAs(OutputType.FILE);
 //Create an instance of Buffered Image from captured screenshot
 BufferedImage img = ImageIO.read(screen);
 // Get the Width and Height of the WebElement using
 int width = element.getSize().getWidth();
 int height = element.getSize().getHeight();
 //Create a rectangle using Width and Height
 Rectangle rect = new Rectangle(width, height);
 //Get the Location of WebElement in a Point.
 //This will provide X & Y co-ordinates of the WebElement
 Point p = element.getLocation();
 //Create image by for element using its location and size.
 //This will give image data specific to the WebElement
 BufferedImage dest = img.getSubimage(p.getX(), p.getY(), rect.width,
 rect.height);
 //Write back the image data for element in File object
 ImageIO.write(dest, "png", screen);
 
 FileUtils.copyFile(screen, new File("E:\\qaautomationworld\\qaautomationworld.png"));
