Setting Environment variables for Java

• JAVA_HOME : C:\Program Files\Java\jdk1.8.0_102
• JDK_HOME : %JAVA_HOME%
• JRE_HOME : %JAVA_HOME%\jre
• CLASSPATH :.;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib
• PATH : your-unique-entries;%JAVA_HOME%\bin (make sure that the longish your-unique-entries does not contain any other references to another Java installation folder.

Notice that all these environment variables are derived from the "root" environment variable JAVA_HOME. This makes it easy to update your environment variables when updating the JDK. Just point JAVA_HOME to the fresh installation.

Solution to 'Could not find the main class, program will exit' while executing runnable file

This error usually happens if there is a conflict in the Java installations. It means there may be more than one installation of Java in your system. Mostly presence of Oracle Jinitiator in C:\Program Files (x86)\Oracle creates this problem.

Perhaps your file associations got messed up. At the command prompt, try running

ftype | find "jarfile"

On my 64-bit Windows 7 computer, that shows

jarfile="C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -jar "%1" %*

You can also change it with ftype:

ftype jarfile="C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -jar "%1" %*

and reboot the system. 

You may also uninstall the Jinitiator which is no longer supported by Oracle as per our knowledge.

Creating Runnable Thread in Java for Selenium User Interface for avoiding no response while execution

UI elements in a User Interface will not respond to the user while execution if a thread is not implemented. Here I will explain how to create a thread so that User Interface will keep responding to the user even when the execution is happening.

Create a class outside the Jframe class

class Multi3 implements Runnable{ 

public void run(){ 
    Url url= new Url();
    url.openurl(javaframe.textField.getText());
}
}

Call the Thread from any actionlistener like below

Multi3 m1=new Multi3(); 
                Thread t1 =new Thread(m1);
                t1.start();

Benefits of having a user Interface for a Selenium Automation Suite/Regression Suite

Once you are able to work independently on Selenium scripting, another important task is how to ease your automation test execution. There are various methods for Selenium  execution. In continuous integration, depending on Jenkins integration is a necessity. Automation execution using Jenkins will enable you to perform mass execution, scheduling etc.

                           I have derived another method which will ease your execution to a certain extent. It is by creating a user interface for your automation framework. It will also give a grant appeal to the framework you have created.

For this you need not have much of UI designing skills. With the help of WindowBuilder addon in Eclipse you can create a UI. I have explained this in a previous post. Please follow the link: Click here

How to export the Project to a runnable JAR

1) You can export the whole project to a runnable JAR with UI class as the main class


a) Export the Project




b) Select Runnable JAR under Java



c)

Against the Launch Configuration dropdown-> Select the UI class as main class 
Enter the destination with .jar extension against Export destination





















d)  Click Finish. Your runnable JAR will be created in the given folder


Benefits of having a user Interface for an Selenium Automation Suite/Regression Suite are:

1) You may select dynamic values like Dev/QA Url from the UI and execute, browser: Chrome, Firefox etc
2) This jar can be executed in any system provided JRE is installed. So developers can do unit testing(Eclipse not required)
