What is appium?

As per official website: Appium is an open-source tool for automating native, mobile web, and hybrid applications on iOS mobile, Android mobile, and Windows desktop platforms. ... Importantly, Appium is "cross-platform": it allows you to write tests against multiple platforms (iOS, Android, Windows), using the same API.

How does it work?

Appium test script written in IDE will interact with the Appium Server which is nothing but the node server with the specified IP address and port number. Node server again passes the request to mobile devices or emulators using the uiautomator or XCUITest as a JSON format. All the UI elements associated with the mobile application can be controlled by using the appium client which is nothing but the derived one of selenium.

Note: Remember using Windows only Android can be automated while in iOS both Android and iOS can be automated.

Install Java 8 and setup environment variable.

Download Java 8 from https://www.oracle.com/java/technologies/javase-jdk8-downloads.html and install it.

Next step is to set environment variables. We will set JAVA_HOME and the path variable.

For Mac

For Mac OSX 10.5 or later, Apple recommends to set the $JAVA_HOME variable to /usr/libexec/java_home, just export $JAVA_HOME in file ~/. bash_profile or ~/.profile.

Open terminal and type (You must be familiar with vi editor commands).

$ vim .bash_profile

Add below lines

export JAVA_HOME=$(/usr/libexec/java_home)

export PATH=${JAVA_HOME}/bin:$PATH

Save the file

Then run below command.

$ source .bash_profile

To confirm if it is set correctly type

$ echo $JAVA_HOME

It should return below path

/Library/Java/JavaVirtualMachines/1.8.xx.jdk/Contents/Home

Type “java -version” to confirm it.

For Windows:

From windows search bar type advanced system settings.

It will open System Properties window.

Select advance tab and click environment variable.

From system variable, click to new button and enter variable name as JAVA_HOME and value as path to JDK installed.

Next we have to edit the system path variable.

 click on New button, and add this %JAVA_HOME%\bin. Click OK

From command prompt type java -version. The output show java version example:

7.         For ex: /Users/username/Library/Android/sdk

8.         Click OK to download start, it will take some time to download all the components.

9.         Close SDK manager.

Setup android environment variable

For Mac

Just like we set JAVA_HOME, set the Android environment variable.

Open terminal and run below commands

$ vim .bash_profile

export ANDROID_HOME=/Users/username/Library/Android/sdk

export PATH=$ANDROID_HOME/platform-tools:$PATH

export PATH=$ANDROID_HOME/tools:$PATH

Save the file.

$ source .bash_profile

Open terminal and type adb version to verify the environment is set properly.

For Windows

Steps for adding environment in windows are same as above for JAVA_HOME and MAVEN_HOME.

Add ANDROID_HOME and value to sdk location under system variable.

Variable Name: ANDROID_HOME

Variable Value: C:\Users\xxxxx\AppData\Local\Android\Sdk

Then add %ANDROID_HOME%\platform-tools and %ANDROID_HOME%\tools in path variable.

For Mac only

So if we add all environment variables then the file will look like this. Yes. there are some extra variables  added which will come to know as you start automating.

export JAVA_HOME=$(/usr/libexec/java_home)

export PATH=${JAVA_HOME}/bin:$PATH

export ANDROID_HOME=/Users/$(whoami)/Library/Android/sdk

export ANDROID_SDK_ROOT=$ANDROID_HOME

export ANDROID_AVD_HOME=/Users/$(whoami)/.android/avd

export PATH=$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$ANDROID_SDK_ROOT/emulator:$PATH

export M2_HOME=/Users/$(whoami)/Downloads/Softwares/Maven

export PATH=$PATH:$M2_HOME/bin

Creating an emulator via android studio

  • Open Android studio.
