Switch between Windows using switch to in Selenium

String MainWinHandle = driver.getWindowHandle();
for(String NewWinHandle : driver.getWindowHandles()){
// Ignore the parent window open and work with the new window frame
 if(!NewWinHandle.equals(MainWindowHandle))
  {
    driver.switchTo().window(NewWinHandle);
 //Perform the required tasks to be performed in the new window opened
 driver.close();
 }
}
//Perform action on the main window once the task is completed with the old window.
driver.switchTo().window(MainWinHandle);

How to execute only failed TestNG tests in Eclipse

While running testNG suite, once we are done with one round of execution of tests in the test suite, It can be helpful to execute only the failed tests during the first round of execution to reduce test failures due to flakiness/synchronization issues.

Below steps shows how to achieve this in eclipse.

• Run the required test suite through eclipse as shown below.

• Once the execution is completed and there are failures in the execution, we may require to rerun the tests.

• Refresh the project. folder test-output should be displayed in the project explorer.

• File testng-failed.xml should be available in the folder.

• Run the test suite in similar manner as shown above, i.e Run As TestNG suite.

Jenkins - Adding a conditional build step.

In Jenkins, at times we may require Jenkins to execute some build step on one condition and another in case of other condition. For e.g: It may be required to run a particular test/batch command on Weekdays and some other batch condition on weekends. We can create a job to perform different tasks based on the condition satisfied. 

To add a conditional build step, follow below steps in Jenkins.

• Navigate to Jenkins>Manage Jenkins>Manage Plugins and go to available tab.
• Search for Conditional buildstep as shown below and click on install without restart.

• It will install the plugin and will show success once installation completes.

• Now the plugin can be used in the Jenkins job as shown below.In the job, add build step as Conditional step (single)

• Provide the conditional step from the list as shown below and execute the build command.

Reload configuration from disk - Jenkins

In case of migration of existing jobs from one Jenkins setup to another setup or removing old build information from the disk, we can use the option to reload configuration from disk in Jenkins. Below are the steps to be be followed to reload configuration from disk:

• When we set up jenkins in a machine, there is a folder with name .jenkins in location c:/users/<UserName> folder.

• When we open the .jenkins>jobs folder, we see the folders for the jenkins jobs we have created in jenkins. 

• We can copy folders from another jenkins instance and paste in this folder. Similarly we can make changes in the logs information or builds information.

• Once we have made the required changes in the jenkins set up. Open Jenkins using localhost:8080 (assuming you are on the jenkins server itself and 8080 is the port used for jenkins and is installed as a window service on the server. Else if accessing from a remote client machine, use the address <machine name>:<port number>

• The jenkins home Page will open as shown below.

• Click on Manage Jenkins and in the Manage Jenkins Page, click on Reload configuration from disk as shown below. This will reload the changes made in jenkins set up.
  

Switching between multiple frames in selenium

There can be multiple iframes in a webPage. To perform action on webelements in a frame, we need to first identify the frame and then perform action on the element.We can switch to a particular frame based on the below identifiers:

By Index: The index depends on the order of frame in the Page. A numeric value is assigned to the frame based on the order in which it appears in the page.

driver.SwitchTo().Frame(0);

By Name: We can switch to a frame based on the name of the frame.

driver.SwitchTo().Frame("FrameName");

By Id: We can switch to a frame based on the id defined for the frame

driver.SwitchTo().Frame("FrameId");

Switch to a frame by locator for WebElement. In the below example frameElement is the locator for the frame

driver.switchTo().frame(frameElement);

e.g: 

driver.SwitchTo().Frame(driver.FindElement(By.CssSelector(cssfortheelement)));

Frame inside frames: There can be scenario in which there are frame inside of the parent frame.Please note in case of frame inside frame, we need to first switch to the outer frame, and then switch to the inner frame to perform action on the webelement.

To acess the main webPage and come out of the frame, below code is used

driver.SwitchTo().DefaultContent()

Importing jobs from one jenkins installation to another

Using Job import plugin, we can import Jenkins job from another machine to our machines. This is useful in migrating jobs from one setup to another or a new Jenkins setup. 

Below are the steps to copy jobs from one Jenkins set up to another.

• We require Job Import plugin to be installed to import job from one machine to another. In case plugin is not installed, Go to Manage Jenkins > Manage Plugins. 

• Click on Available tab and search for Job import plugin.

• Select the checkbox and click on Install without restart.

• Once Jenkins is installed, Job Import plugin will be displayed in the menu.

• Next to import the jobs from another Jenkins URL, click on Job Import plugin

• Provide the Remote Jenkins URL and credential to connect to Jenkins and click on Query!

• Once we click on Query!, Jenkins job will be displayed from the remote Jenkins.

• Select jobs to be imported and click on import.

• Jobs will be imported once user clicks on Import.

How to run Jenkins on port other than 8080

By default Jenkins start at port 8080, but at times port 8080 is already used by some other application. We can run Jenkins on port other than 8080 by following below steps:

• In case jenkins is running through command prompt, we can start jenkins to run at port 9090 or any other port using below command:

java -jar jenkins.war --httpPort=9090

• To change the port permanently, follow below steps:

• Go to jenkins home folder. The jenkins home folder is usually at C:\Program Files (x86)\Jenkins in case jenkins is installed from microsoft installer (MSI) file or it can be c:\Users\<UserName>\.jenkins folder.

• Open the jenkins.xml file.

• Change the port number in the file to the required port number.

• Save the file.

• Restart the window service for jenkins.
