How to Set Up Continuous Integration with Eclipse, Selenium Webdriver, Maven and Hudson

Prerequisites:

1.    Download the latest java jdk from here: http://www.oracle.com/technetwork/java/javase/downloads/index.html
2.    Download the latest build for eclipse(java ee developers) from here: http://www.eclipse.org/downloads/
3.    Download the latest apache maven from here: http://maven.apache.org/download.cgi
4.    Download the latest Hudson from here: http://hudson-ci.org/

Steps:

1.    Install the Java JDK and set the JAVA_HOME environment variable to point to the path where Java JDK was installed (on a windows 7 system the environment variables can be accessed by right clicking your Computer, select Properties, then Advanced system settings, then press the Environment Variables… button)

2.    Unpack the maven archive, then set the MAVEN_HOME env variable to point to the path where maven was installed

3.    Set the Path variable to both: %JAVA_HOME%\bin and %MAVEN_HOME%\bin

4.    To check everything is ok, open a command prompt and type: java –version to see the current version of the java jdk installed and also mvn to see if the command is recognized by the system

5.    Unpack the eclipse archive to a local directory and create a shortcut for it on Desktop and start it
6.    Choose a directory for your workspaces

7.    Go to Help -> Eclipse Marketplace and search for m2eclipse, then choose Maven Integration for Eclipse

8.    Click Next on the following screen

9.    Accept the license and click Finish

10.    Restart eclipse

11.    Go to the workspaces folder and create a new folder for your project
12.    In that folder copy the following pom.xml file:
Just make sure the versions for:

selenium-java
                2.42.0 and 
junit
4.11 are set to the latest available

13.    Open a command prompt and run “mvn clean install” in that directory where the pom.xml file is located:

14.    Wait for the build to be completed, then run “mvn eclipse:eclipse”

15.    You now have an eclipse project generated for you

16.    Go to eclipse, choose File -> Import, then Existing projects into workspace

17.    Click Next then select the path to the previously created project folder

18.    Your project will be imported and it will look something like this:
19.    In eclipse right click the project folder and select New-> Source Folder and give it the name: “src” then click Finish

20.    Select the src folder, right click on it, select New -> Package and give it the name: “test.java”

21.    Right click the test.java package and select New -> Class and name it CI_StarterTest, uncheck the Inherited abstract methods option and click Finish (the class name must have the word Test in it!)

22.    Copy the contents of this file in the java class you’ve just created
23.    Your project should now look like this:
24.    To make sure everything works fine, go to your project folder and start a command prompt in that folder, the run the command: “mvn clean install”, you should have a successful build

Hudson configuration

1.    Copy the war file to a directory of your convenience
2.    Create a bat file to run it, call it runHudson.bat, it will contain: “java –jar hudson.war”, I’ve attached it here for you convenience, just copy it to the hudson folder
3.    Run the file and wait for hudson to start

4.    You can now access hudson on: http://localhost:8080/
5.    Make sure you check the maven plugins(x3)

6.    Click Install on the bottom of the page

7.    It will take a while… you can take a break while it finishes
8.    Click Finish when it is done

9.    Hudson is now ready

10.    Click on New Job link and name it CI

11.    On the configuration page, under Advanced Project options check the Use custom space checkbox and paste in the path to your project folder

13.    Click Save
14.    Run the build and check the status
15.    Congrats, you are all done, now you can move along to add all of sorts of tests in your newly configured CI

Learn Maven

1.  Archetype : Used to create Project with same pattern like Hibernate Project, Web project etc.

command : mvn archetype :generate

Get total number of rows from a HtmlTable – Webdriver

public static int getRowCount(WebElement element) throws Exception {
try {
WebElement table =element;
@SuppressWarnings(“rawtypes”)
List rows = table.findElements(By.tagName(“tr”));
return rows.size();
} catch (Exception e) {
return -1;
}

Most common functions used in WebDriver to make a web-application testing.

1. IsElementPresent/Text Present
   1. Finding elements by using function that take argument of By classprivate boolean isElementPresent(WebDriver driver, By by)
try{
driver.findElement(by);
return true;
}
catch(Exception e)
{
return false;
}
}
   2. Using the size to decide whether element is there or not
      if(driver.findElements(Locator).size()>0
{
return true
}else
{
return false
}
}
   3. Finding the text using the PageSourcedriver.PageSource.Contains("TEXT that you want to see on the page");
2. Finding WebElement  by using various locators
   1. Using ID  WebElement welement = driver.findElement(By.id("Id from webpage"));
   2. Using Name  WebElement welement = driver.findElement(By.name("Name of WebElement"));
   3. Using Tag Name  WebElement welement = driver.findElement(By.tagName("tag name"));
   4. Using Xpath  WebElement welement = driver.findElement(By.xpath("xpath of  webElement"));
   5. Using CSS  WebElement welement = driver.findElement(By.CSS("CSS locator path"));
   6. Using LinkText  WebElement welement = driver.findElement(By.LinkText("LinkText"));
3. Fetching pop-up message
   this is the function that would help you in fetching the message
   
public static String getPopupMessage(final WebDriver driver) {
String message = null;
try {
Alert alert = driver.switchTo().alert();
message = alert.getText();
alert.accept();
} catch (Exception e) {
message = null;
}
System.out.println("message"+message);
return message;
}
4. Canceling pop-up
   public static String cancelPopupMessageBox(final WebDriver driver) {
String message = null;
try {
Alert alert = driver.switchTo().alert();
message = alert.getText();
alert.dismiss();
} catch (Exception e) {
message = null;
}
return message;
}
5. Inserting string in Text Fieldpublic static void insertText(WebDriver driver, By locator, String value) {
WebElement field = driver.findElement(locator);
field.clear();
field.sendKeys(value);
}
6. Reading ToolTip text
   public static String tooltipText(WebDriver driver, By locator){
String tooltip = driver.findElement(locator).getAttribute("title");
return tooltip;
}
7. Selecting Radio Button
   public static void selectRadioButton(WebDriver driver, By locator, String value){ List select = driver.findElements(locator);
for (WebElement element : select)
{
if (element.getAttribute("value").equalsIgnoreCase(value)){
element.click();
}
}
8.  Selecting CheckBox
   
public static void selectCheckboxes(WebDriver driver, By locator,String value)
{
List abc = driver.findElements(locator);
List list = new ArrayListArrays.asList(value.split(",")));
for (String check : list){
for (WebElement chk : abc){
if(chk.getAttribute("value").equalsIgnoreCase(check)){
chk.click();
}}}}
9. Selecting Dropdownpublic static void selectDropdown(WebDriver driver, By locator, String value){
new Select (driver.findElement(locator)).selectByVisibleText(value); }
10. Selecting searched dropdownpublic static void selectSearchDropdown(WebDriver driver, By locator, String value){
driver.findElement(locator).click();
driver.findElement(locator).sendKeys(value);
driver.findElement(locator).sendKeys(Keys.TAB);
}
11. Uploading filepublic static void uploadFile(WebDriver driver, By locator, String path){
driver.findElement(locator).sendKeys(path);
}
12. Downloading fileHere we will click on a link and will download the file with a predefined name at some specified location.
    public static void downloadFile(String href, String fileName) throws Exception{
URL url = null;
URLConnection con = null;
int i;
url = new URL(href);
con = url.openConnection();
// Here we are specifying the location where we really want to save the file.
File file = new File(".//OutputData//" + fileName);
BufferedInputStream bis = new BufferedInputStream(con.getInputStream());
BufferedOutputStream bos = new BufferedOutputStream(
new FileOutputStream(file));
while ((i = bis.read()) != -1) {
bos.write(i);
}
bos.flush();
bis.close();
13. Wait()
    1. Implicit Wait :
       driver.manage.timeouts().implicitlyWait(10,TimeUnit.SECONDS);
    2. Explicit Wait:WebDriverWait wait = new WebDriverWait(driver,10);
wait.until(ExpectedConditons.elementToBeClickable(By.id/xpath/name("locator"));
    3.  Using Sleep method of java
       Thread.sleep(time in milisecond)
14. Navigation method of WebDriver Interface
    
    
    1. to() method (its a alternative of get() method)
       driver.navigate().to(Url);
       This will open the URL that you have inserted as argument
    2. back() – use to navigate one step back from current position in recent history syntax == driver.navigate().back();
    3. forward() – use to navigate one step forward in browser historydriver.navigate().forward();
    4. refresh() – This will refresh you current open urldriver.navigate().refresh();
15. Deleting all Cookies before doing any kind of action  driver.manage().deleteAllCookies();
    This will delete all cookies
16. Pressing any Keyboard key using Action builder class of WebDriverWebDriver has rewarded us with one class Action to handle all keyboard and Mouse action. While creating a action builder its constructor takes WebDriver as argument. Here I am taking example of pressing Control key
    Actions builder = new Actions(driver);
builder.keyDown(Keys.CONTROL).click(someElement).click(someOtherElement).keyUp(Keys.CONTROL).build().perform();When we press multiple keys or action together then we need to bind all in a single command by using build() method and perform() method intend us to perform the action.
    In the same way you can handle other key actions.
17. Drag and Drop action in Webdriver
    In this we need to specify both WebElement means Source and target and for draganddrop Action class has a method with two argument so let see how it normally look like
    WebElement element = driver.findElement(By.name("source"));
WebElement target = driver.findElement(By.name("target"));
(new Actions(driver)).dragAndDrop(element, target).perform();

ADB is Not Recognized as an internal or external command Fix

Some of you are facing problems with Path, because of that you will see the error as below. Even though it is basic lot of people asking this same question. Hence posting this tutorial to fix this error.

In Windows --> Click Start --> Run --> cmd

When you run adb in the command prompt you will see an error as below

Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

C:\Users\raj>adb
'adb' is not recognized as an internal or external command,
operable program or batch file.

To fix this error you need the Android SDK if you don't have it please follow the steps below,

Open the browser and navigate to http://developer.android.com/index.html

Click the Get the SDK as shown in the above image

Click Download the SDK as shown in the above image

Check the checkbox for the license agreement, Select 32 or 64 bit based on your operating systtem.

Click the download SDK link.

Wait patiently until the download is complete.

My machine is a 64 bit Windows, hence the file downloaded is adt-bundle-windows-x86_64-20130219.zip

The zip file contains the following folders eclipse & sdk.

I have extracted to the following location in my machine

Hence i have the following in the path 

C:\Users\rajb\Downloads\adt-bundle-windows-x86_64\sdk\platform-tools

C:\Users\rajb\Downloads\adt-bundle-windows-x86_64\sdk\tools

To Fix it permanently set in the environment variable 

Right Click My Computer --> Click Properties 

Click Advanced System Settings 

Click Environment Variables

Click New  as below, 

Variable name: ANDROID_PLATFORM_TOOLS

Variable Value: C:\Users\rajb\Downloads\adt-bundle-windows-x86_64\sdk\platform-tools

Variable name: ANDROID_TOOLS

Variable Value: C:\Users\rajb\Downloads\adt-bundle-windows-x86_64\sdk\tools

Edit the Path variable if it exist, else create a new variable Path 

Variable name: Path

Variable Value: %Path%;%ANDROID_PLATFORM_TOOLS%;%ANDROID_TOOLS%

adb should be working on command prompt and 'adb' is not recognized as an internal or external command,

operable program or batch file is resolved now.

 

 Connect the device with USB then from the command line
