Benefits of Robotium

Prerequisites

1) Download and Install JAVA

– Download Java from this page.

– Add java libraries to the PATH and set JAVA_HOME to the root of java installation directory in your environment.

2) Download ADT Bundle

Creating a Robotium Project

Only a few steps required to create a project,

Step #1: Open eclipse contains your android application to be tested.

(Click on image to enlarge)

Step #2: Right-click on the android project -> Android Tools and click on the new Test project.

Step #3: Give a name for the Test project and click Next button.

Step #4: Select The Application under test as the target and click finish button.

Step #5: Test project will be created in the eclipse workspace.

Step #6: Download Robotium solo jar from here.

Step #7: Right click on the Test project in the workspace Go to the Build path and click Configure build path.

Step #8: Switch to libraries tab, click on “Add external jars” option and browse the downloaded Robotium jar file and add it to the libraries and click “OK”.

Step #9: Robotium Test project is created successfully. Now we can create classes under the project and start writing the test cases.

Creating Robotium Class

#1: Right click on the package under src directory in the Test project, and create a new class.

#2: Import the Main Activity class the Robotium test project.

Syntax:

 import com.sasi.attendanceproject.Home; 

#3: New class will inherit properties from ActivityInstrumentationTestCase2 class

 
public class AttendanceTest extends
ActivityInstrumentationTestCase2 <home> 

(Note: Here, Home is the activity to be tested in the Android application)

#4: Create Instance for Solo class as below

 private Solo solo; 

#5: Create a Constructor for the Test class, as below

public AttendanceTest() {
    super(Home.class);
    // TODO Auto-generated constructor stub

#6: Create setUp and tearDown methods, as below

Setup method is used to Initiate the Instrumentation

public void setUp()throws Exception
{
   solo=new Solo(getInstrumentation(), getActivity());
} 

Teardown method is used to close the activity after the test has been completed.

 public void tearDown() throws Exception
 { solo.finishOpenedActivities();
 } 

Some Robotium Methods

#1. assertCurrentActivity (text,Activity)

This method verifies whether the current activity is the activity which is passed as the send parameter.

Syntax

solo.assertCurrentActivity("Current Activity", Home.class);

#2. clickOnButton(text)

This method will click on the button with the specified Text.

Syntax:

solo.clickOnButton("ADMIN");

#3. clickOnButton(int)

This method will click on the button with the specified index.

Syntax:

solo.clickOnButton(2);

#4. waitForText(text)

This method will wait until the text appearing on the activity.

Syntax:

solo.waitForText("Creating New Password");

#5. enterText(int, text)

This method will type the text passed as the second parameter to the specified index edit box.

Syntax:

solo.enterText(0,"test");

#6. clickOnCheckbox(int)

This Method will click on the checkbox with given index.

Syntax:

solo.clickOnCheckBox(0);

#7. clickOnRadioButton(int)

This Method will click on the Radio button with the given index.

Syntax:

solo.clickOnRadioButton(1);

#8. clickOnImage(int)

This Method will click on the image with the given index.

Syntax:

solo.clickOnImage(1);

#9. clearEditText(int)

This Method will clear the text in the edit box with the given index.

Syntax:



solo.clearEditText(0);

#10. waitForText(text)

This Method will wait until the given text is appearing on the activity.

Syntax:

solo.waitForText(“Robotium”); 

Example Program

Locating Elements in Android Application

Step – 1

Open Eclipse containing Android Application to be Tested.

Step – 2

Expand the project, Go to res? Layout folder and double click on the activity XML file, you want to automate. It will open the designed activity in the eclipse editor.

Step – 3

Locating Button Element

Locating Element By ID

Click on the Element, you want to locate. On the right side properties panel, you can find the ID of that element. (ignore @+id/)

(Click on image to enlarge)

In the Above figure ID of the element is, btnadmin.

Corresponding Robotium code to locate this button is,

solo.clickOnButton(R.id.btnadmin);

Locating Element By Position

In case, if ID is not available then you can locate the element using the order. If the button is in the second position, Then you can locate the button by,

solo.clickOnButton(1);

Locating Element By Text

Even you can click on the button using the text displayed on the button.

Solo.clickOnButton(“ADMIN”);

Locating Text box Element

Using Similar way click on the text box you want to enter data and find the position of the text box from the right side.

Solo.enterText(0,”Anitha”);
//Username textbox is in 1st position
Solo.enterText(1,”test”);  
//Password textbox is in 2nd position 

Locating a Radio Button Element

Click on the Radio Button Element, you want to click and find out the position of the radio button.

 Solo.clickOnRadioButton(1);
//It will location radio button in the second position. 

Sample Code


package com.sasi.attendanceproject.test;
import android.test.ActivityInstrumentationTestCase2;
import android.widget.EditText;

import com.robotium.solo.By;
import com.robotium.solo.Solo;
import com.robotium.solo.WebElement;
import com.sasi.attendanceproject.Home;

public class AttendanceTest extends ActivityInstrumentationTestCase2<Home>{
    private Solo solo;
    public AttendanceTest() {
        super("com.sasi.attendanceproject.Home",Home.class);
        // TODO Auto-generated constructor stub
    }

    public void setUp()throws Exception{
        solo=new Solo(getInstrumentation(),getActivity());
    }
    public void testAttendance()throws Exception{
        //solo.assertCurrentActivity("Current Activity", Home.class);
        solo.waitForWebElement(By.id("btnadmin"));
        solo.clickOnButton("ADMIN");
        solo.clickOnButton(0);
        solo.waitForText("Creating New Password");
        solo.enterText(0, "test");
        solo.enterText(1, "test");
        solo.clickOnButton("Okay");
        solo.waitForText("Attendance Login");
        solo.enterText(0, "Anitha");
        solo.enterText(1, "test");
        solo.clickOnButton("Login");
        solo.waitForWebElement(By.id("btnaddnew"));
        solo.clickOnButton("Add New Details");
        solo.waitForText("Enter the Employee Details");
        solo.enterText(0, "Anitha");
        solo.enterText(1, "6");
        solo.enterText(2, "Testing Engineer");
        solo.clickOnRadioButton(1);
        solo.clickOnButton("Okay");
        solo.waitForWebElement(By.id("tvempID"));
        System.out.println(solo.getText(0));

    }
    public void tearDown()throws Exception{
        solo.finishOpenedActivities();}}

Executing Robotium Project

From Eclipse:

Right-click on the project and select Run As -> Android JUnit Test

From Command Prompt:

Step 1:

Cd to your Android Test Project Directory

Step 2:

Run the following command,

 adb shell am instrument -w <<package name of your test
class>>/android.test.InstrumentationTestRunner
