How to convert a String Array to a Collection? Before we get to know how to convert a String Array into a Collection. We might want to know more details about the two… What’s the difference between a String Array and a Collection? Collection: It’s a group of data manipulated as a single object. Technically, its an interface in java which is implemented by various other classes. Many of which you uses regularly. One of its implementations can be seen in an array. An array best defined by the Sun is “An array is a container object that holds a fixed number of values of a single type.” So by implementing Collection interface, an Array skips the code required for its implementation – that is now taken care by the Collection interface! Why would I want to  convert a String Array into a Collection A Collection contains “Objects” if you understand the language…An Object is more generic implementation of the data types. So in a Collection, you can have any type of Object…So while w...

Many a times we would want to write up a script to start the selenium server using a shell script… So here is the script     #!/bin/sh # # @Author – Sirisha # @Date   - May 29 2012 # Script to start the Selenium Server on a given host #   # Defined the hostname hostname=somehostname # Defined the path to the selenium server serverPath=~/seleniumServer/ # Define the Selenium Server version jar server=selenium-server-standalone-2.12.0.jar # Define the Search String for the server SERVICE_STRING="'java -jar $server'"   # Clear the terminal clear   echo "service string is: $SERVICE_STRING" echo "Starting Selenium Server on $hostname"   # Run the command to get the process list ps -ef | grep -v grep | grep selenium   # Check if the Selenium Server is already running if [ $? -eq 0 ] then     echo "$server is running, everything is fine" else     echo "$server is not running"  ...

This is nothing new but yet I thought why not document it so that its etched into my memory (Ya I know I am selfish ) When you run a command or try executing a shell script, the shell first tries to look if your script is found in the Current Directory. To execute a shell script you should be in the same directory where it was created/written. Now this isn’t possible always – so what to do? There are two ways:   Method 1 - When you are executing the script, give the full path to the script! Now if you go by the usual file/folder structure in most of the software engineers – you can go crazy with the paths – the depth at which the script is found can drive you insane   So thankfully we have another way   Method 2 - Add the folder of your script to the PATH variable. What I suggest is create a folder for all your scripts – say myScripts and then add this to your PATH variable. If you are new to using the PATH variable, I suggest you go through this link on PATH ...

It took me some time to get a hang of what the TestNG DataProvider could do…Once I got to know about how it functions believe me I created wonders with it   What is a TestNG DataProvider? There are loads of definitions on the web for it but if you are an average-but-wanting-to-learn software engineer then in simple words, a TestNG DataProvider is a Test Data Provider class…Simple! It is powerful enough to provide data according to the method which is initiating or rather calling it…   When/Why do I need a TestNG DataProvider? Of course, most of us would agree that we provide the test data through various forms like an xml, excel, csv etc…The reason I found this feature useful when I knew the input before hand and it varied based on the test case…For example, if I am testing buying of a product on a retail website…I want to test buying of a new product, buying of a used product, buying of multiple products…I have the test data in all the three cases but then the test data...

who : gets all the connections made to your account netstat –antp : to know all the process running on ports sudo /etc/init.d/network restart : restart networking on your linux box Understanding the init.d Directory – This directory has the control scripts for most of the services on our linux box. The start/stop/restart/reload/force-reload options can be used with any command found under this directory Most common Services controllable from this directory are: apache2, sshd, networking, ftpd, samba, mysql You can run any command using the following format: sudo /etc/init.d/<command> <option> where command can be apache2, sshd, networking etc and option can be start, stop, restart etc For ex: sudo /etc/init.d/networking restart Simple!
